Evaluation of the skin surface showed a significant decrease of skin roughness and scaling in the high flavanol cocoa group compared with those at wk 12. Dietary flavanols from cocoa contribute to endogenous photoprotection, improve dermal blood circulation, and affect cosmetically relevant skin surface and hydration variables.

In moderately photo-aged women, regular cocoa flavanol consumption had positive effects on facial wrinkles and elasticity. Cocoa flavanol supplementation may contribute to the prevention of the progression of photo-aging. This trial was registered at clinicaltrials.gov as NCT02060097.

Our study failed to demonstrate a statistically-significant protective effect of HFC vs. LFC consumption on skin sensitivity to UV radiation as measured by MED.

Coconut oil is as effective and safe as mineral oil when used as a moisturizer.

VCO and monolaurin's O-SSI reduction and in vitro broad-spectrum activity against SA (given clinical validity here), fungi, and viruses may be useful in the proactive treatment of AD colonization.

In conclusion, our results indicate that PD-Feverfew extracts have potent anti-inflammatory activity suggesting that this botanical would be efficacious in relieving inflammation without inducing immune sensitization.

Clinical efficacies of the ginkgo formula and the formula containing a mixture of tea and rooibos were compared following 28 days of application. The ginkgo preparation increased skin moisturization (27.88%) and smoothness (4.32%) and reduced roughness (0.4%) and wrinkles (4.63%), whereas the formula containing tea and rooibos showed the best efficacy on wrinkle reduction (9.9%). In comparison to the tea and rooibos formula, gingko significantly improved skin moisturization (P = 0.05).

A statistically significant cessation of active progression of depigmentation was noted in patients treated with G. biloba (P = 0.006). Marked to complete repigmentation was seen in 10 patients in group A, whereas only two patients in group B showed similar repigmentation. The G. biloba extract was well tolerated. G. biloba extract seems to be a simple, safe and fairly effective therapy for arresting the progression of the disease.

The criteria for feasibility were met after increasing the maximum age limit of the successful recruitment criterion; participant retention, safety and effectiveness criteria were also met. Ingestion of 60 mg of Ginkgo biloba BID was associated with a significant improvement in total VASI vitiligo measures and VETF spread, and a trend towards improvement on VETF measures of vitiligo lesion area and staging. Larger, randomized double-blind clinical studies are warranted and appear feasible.

Tinospora cordifolia lotion exhibits anti-scabies activity comparable with permethrin. Its incorporation as therapeutic reagent in Sarcoptes scabiei infections is highly recommended.

MYO administration is a simple and safe treatment that ameliorates the metabolic profile of patients with PCOS, reducing hirsutism and acne.

The use of inositol supplements is worth considering for patients with intractable psoriasis who need to continue to take lithium for bipolar affective disorders.

The results obtained in this study clearly showed the beneficial effect of Silymarin, N-acetylcysteine and Selenium to patients with acne vulgaris as indicated by the clinical improvement that strongly and positively correlated with improvement in biochemical data.

In this 48-week study of 381 women with female pattern hair loss, 5% topical minoxidil was superior to placebo on each of the 3 primary efficacy end points: promoting hair growth as measured by change in nonvellus hair count and patient/investigator assessments of hair growth and scalp coverage.

Hair count results show a modest and sustained improvement in hair growth with daily use of a 1% pyrithione zinc shampoo over a 26-week treatment period.

In contrast, the 5% and 2% minoxidil treatment groups showed a statistically significant increase in mean percentage change in interval weight from baseline compared with placebo; results for number counts were usually less significant. Over 96 weeks, topical minoxidil induced and maintained an increase in interval weight over baseline of about 30%. After treatment was stopped, hair weight and number counts for the minoxidil groups returned to about the same levels as placebo in 24 weeks.

In men with AGA, 5% topical minoxidil was clearly superior to 2% topical minoxidil and placebo in increasing hair regrowth, and the magnitude of its effect was marked (45% more hair regrowth than 2% topical minoxidil at week 48). Men who used 5% topical minoxidil also had an earlier response to treatment than those who used 2% topical minoxidil. Psychosocial perceptions of hair loss in men with AGA were also improved. Topical minoxidil (5% and 2%) was well tolerated by the men in this trial without evidence of systemic effects.

In this comparative study of systemic finasteride and topical minoxidil, it was concluded that both drugs were effective and safe in the treatment of mild to severe AGA, although oral finasteride treatment was more effective (p < 0.05). Adverse events were not considered important either, and these side effects disappeared as soon as the treatment was stopped.

Once-daily 5% MTF is noninferior and as effective for stimulating hair growth as twice-daily 2% MTS in women with androgenetic alopecia and is associated with several aesthetic and practical advantages.

The difference between the groups was significant (P = 0.020). The incidence of adverse events was 8.7% (13/150) in the 5% group and 5.3% (8/150) in the 1% group, with no significant difference between the groups (chi(2)-test: P = 0.258). Our findings confirmed the superiority of 5% topical minoxidil to 1% topical minoxidil in treating Japanese men with androgenetic alopecia.

We believe that 5% MTF is a safe and effective treatment for men with AGA.

Overall, the results obtained were better than those observed with the same formula containing 1% of zinc gluconate, an ingredient frequently used in oily skin care products.

Oral administration of PL is an effective systemic chemophotoprotective agent leading to significant protection of skin against UV radiation.

Our data indicate that oral PL treatment might be beneficial for the prevention of PLE.

PL complete absence of toxicity combined with its multifactorial protection, makes it an effective and safe treatment for photoprotection in IP.

PL extract administration has shown to be an effective and safe method, leading to a significant protection of skin in IP.

This pilot study showed positive results for resveratrol gel in acne, and should be considered a valid starting point for further testing of the effectiveness of this molecule in different concentrations and formulations and in a larger group of patients.

Fourteen of the 15 patients who received tretinoin to the face had improvement in photoaging, whereas none of the vehicle-treated patients' faces improved, a statistically significant difference in response between the two groups. Statistically significant histologic changes were seen in forearm skin treated with tretinoin, but not with vehicle cream. Side effects were limited to irritation of tretinoin-exposed skin.

Significant reductions were found in fine wrinkling, mottled hyperpigmentation, roughness, and laxity after 0.05% tretinoin therapy when compared with controls. In addition, histologic changes of increased epidermal thickness, decreased melanin content, and stratum corneum compaction provide independent evidence supporting clinical improvement. Side effects of erythema, peeling, and stinging were usually mild and well tolerated.

Topical retinol improves fine wrinkles associated with natural aging. Significant induction of glycosaminoglycan, which is known to retain substantial water, and increased collagen production are most likely responsible for wrinkle effacement. With greater skin matrix synthesis, retinol-treated aged skin is more likely to withstand skin injury and ulcer formation along with improved appearance.

Tretinoin 0.1% and 0.025% produce similar clinical and histologic changes in patients with photoaging, despite significantly greater incidence of irritation with the higher concentration. The separation between clinical improvement and irritation suggests that mechanisms other than irritation dominate tretinoin-induced repair of photoaging in humans.

It has been found that 1-methylnicotinamide (MNA+), a metabolite of nicotinamide, possesses significant anti-inflammatory properties. MNA+ is chemically stable, non-toxic and well tolerated. MNA+ can be used to treat wide variety of diseases and disorders and the use of this compound provides certain advantages over the use of nicotinamide.

No major side effect was encountered by any patient. Skin type is a significant factor in choosing between topical nicotinamide and clindamycin in patients with acne vulgaris.

These data demonstrate that 4% nicotinamide gel is of comparable efficacy to 1% clindamycin gel in the treatment of acne vulgaris. Because topical clindamycin, like other antimicrobials, is associated with emergence of resistant microorganisms, nicotinamide gel is a desirable alternative treatment for acne vulgaris.

In addition to previously observed benefits for topical niacinamide, additional effects were identified (improved appearance of skin wrinkles and yellowing and improved elasticity).

The data suggest niacinamide is an effective skin lightening compound that works by inhibiting melanosome transfer from melanocytes to keratinocytes.

A topical formulation of zinc pyrithione can be used to treat localized psoriasis.

Minocycline and zinc gluconate are both effective in the treatment of inflammatory acne, but minocycline has a superior effect evaluated to be 17% in our study.

Patients on placebo showed no improvement. After 12 weeks of treatment with zinc sulphate, 17 patients (58%) showed significant improvement. There was a statistically significant decrease in the number of papules, infiltrates and cysts. In zinc-treated cases there was statistically significant increase in serum vitamin A levels, while no change was found in the placebo group.

Pruritus was decreased in both groups after treatment but there was a significantly greater decrease in the zinc sulfate group compared with placebo (P = 0.018). Patient compliance was good and no severe side effects were observed. Zinc sulfate (440 mg/day) is more effective than placebo for the relief of pruritus in patients under maintenance hemodialysis. Further studies with larger sample size, longer treatment duration and follow-up and with various dosages of zinc sulfate are recommended.

The effect of zinc on acne is unclear. In this study, only patients with an inflammatory acne were included in a double-blind trial using low doses of zinc gluconate (200 mg/day, corresponding to 30 mg zinc metal). We obtained a significantly different result between zinc and placebo groups in the inflammatory score (p less than 0.02). This efficiency could be explained by the action of zinc on inflammatory cells, especially granulocytes.

Various methods for the clinical evaluation of acne were studied. Counting of acne lesions was found to be a more precise method than assessment according to the opinion of the patients and the assessment of colour photographs. The correlation between the results obtained by lesion counting and evaluation by photographs was low, as was also the reproducibility of photographic assessment.

Self-evaluations were also made by the study participants. There was a significant improvement in skin quality in both objective and subjective parameters after treatment with Dermavite compared with placebo. Participants' self-evaluations also showed a statistically significant difference in favour of the active treatment. The treatment was very well tolerated. Based on this efficacy and tolerability study, DermaVite can be considered a suitable therapy for ageing symptoms of the skin.

A significant decrease in skin thickness measured by B-mode ultrasound was elicited, as was a significant improvement in elasticity measured with a Cutometer as compared with controls. In cheek skin, the thickness normally increases and the elasticity usually decreases with age. These results suggest that the Fucus vesiculosus extract possesses anti-aging activities and should be useful for a variety of cosmetics.

The treatment was always well tolerated without adverse effects. The present findings seem to indicate that the topical application of BAs may represent a suitable treatment option for selected features of skin photoaging.

Chia seed oil can be used as an adjuvant moisturizing agent for pruritic skin, including that of ESRD patients.

Overall, taking chromium for 8 weeks among women with PCOS had beneficial effects on acne, hirsutism, hs-CRP, TAC, and MDA levels, but it did not affect endocrine profiles, NO, and GSH.

Our data let us postulate that energy metabolism shifts to a predominantly non-mitochondrial pathway and is therefore functionally anaerobic with advancing age. CoQ10 positively influences the age-affected cellular metabolism and enables to combat signs of aging starting at the cellular level. As a consequence topical application of CoQ10 is beneficial for human skin as it rapidly improves mitochondrial function in skin in vivo.

The results suggested that moringa cream enhances skin revitalization effect and supports anti-aging skin effects.

Oral n-3 PUFAs appear to abrogate photoimmunosuppression in human skin, providing additional support for their chemopreventive role; verification of study findings is required. This trial was registered at clinicaltrials.gov as NCT01032343.

Reduction in this range of early markers, i.e. sunburn, UVR-induced p53 in skin and strand breaks in PBL, indicate protection by dietary EPA against acute UVR-induced genotoxicity; longer-term supplementation might reduce skin cancer in humans.

Thus, omega-3 fatty acids may act as an oxidizable buffer, protecting more vital structures from free radical damage.

The beneficial effects of GSE was maximally achieved after 6 months and these was no further improvement after this period. The latter GSE intake for 5 months may prevent chloasma from becoming worse prior to the summer season. GSE is safe and useful for improving chloasma.

Intake of the green tea polyphenol beverage for 12 wk increased blood flow and oxygen delivery to the skin. Likewise, in a separate, randomized, double-blind, single-dose (0.5, 1.0, and 2.0 g) study of green tea polyphenols, blood flow was maximized at 30 min after ingestion. In summary, green tea polyphenols delivered in a beverage were shown to protect skin against harmful UV radiation and helped to improve overall skin quality of women.

Dietary hempseed oil caused significant changes in plasma fatty acid profiles and improved clinical symptoms of atopic dermatitis. It is suggested that these improvements resulted from the balanced and abundant supply of PUFAs in this hempseed oil.

This study provides skin-physiological and for the first time molecular evidence that Pycnogenol supplementation benefits human skin by increasing skin hydration and skin elasticity. These effects are most likely due to an increased synthesis of extracellular matrix molecules such as hyaluronic acid and possibly collagen. Pycnogenol supplementation may thus be useful to counteract the clinical signs of skin aging.

When applied topically to the scalp and facial skin, 0.01% RK promoted hair growth in 50.0% of humans with alopecia (n=10) at 5 months after application and increased cheek skin elasticity at 2 weeks after application in 5 females (p<0.04). These observations strongly suggest that RK might increase dermal IGF-I production through sensory neuron activation, thereby promoting hair growth and increasing skin elasticity.

RCE supplementation exerted a subject improvement of scalp hair and skin status as well as libido, mood, sleep, and tiredness in postmenopausal women.

Results suggest that intake of the standardized rose hip powder (Hyben Vital(®)) improves aging-induced skin conditions. The apparent stabilizing effects of the rose hip product on cell membranes of stored erythrocyte cells observed in this study may contribute to improve the cell longevity and obstructing skin aging.

Our investigation into the AD-mitigating effect of rosmarinic acid through in vivo experiments demonstrated the possible clinical use of rosmarinic acid as a therapeutic agent for AD.

We also clinically observed, that finasteride acts in both the front area and the vertex, while Serenoa repens prevalently in the vertex. Obviously other studies will be necessary to clarify the mechanisms that cause the different responses of these two treatments.

In conclusion, this trial demonstrated that supplementation with tocotrienol capsules increases hair number in volunteers suffering from hair loss as compared to the placebo group. This observed effect was most likely to be due to the antioxidant activity of tocotrienols that helped to reduce lipid peroxidation and oxidative stress in the scalp, which are reported to be associated with alopecia.

It is concluded that neither topical steroid nor topical vitamin E is effective in reducing scar formation after grafting procedures for reconstruction for postburn contractures.

This study shows that there is no benefit to the cosmetic outcome of scars by applying vitamin E after skin surgery and that the application of topical vitamin E may actually be detrimental to the cosmetic appearance of a scar. In 90% of the cases in this study, topical vitamin E either had no effect on, or actually worsened, the cosmetic appearance of scars. Of the patients studied, 33% developed a contact dermatitis to the vitamin E. Therefore we conclude that use of topical vitamin E on surgical wounds should be discouraged.

A combination of 1% vitamin K and 0.3% retinol in acrylates copolymer cream hastened the resolution of laser-induced purpura.

Vitamin K oxide gel appears to hasten the resolution of pulsed dye laser-induced purpura in subjects being treated for bilateral facial telangiectasia, and may well be useful in accelerating resolution of facial bruising from other cosmetic procedures such as fillers used for soft-tissue augmentation as well as other types of cutaneous surgical procedures.

The mean MASI score significantly improved from 4.076 (± 0.24) at baseline to 2.884 (± 0.25) at week 8 for the 75% mulberry extract oil group while the placebo group showed an improvement of a lesser magnitude.

In conclusion, NAC decreases oxidative stress in workers exposed to lead via stimulating GSH synthesis.
