In this study, a new apple stem cell extract serum significantly improved signs of skin aging and enhanced cell metabolism in human senescent fibroblasts, showing visible effects after one week of use.

In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.

In this open-label study, participants reported that the LustrivaTM BH-002 two-step system improved various aspects of hair, skin, and nail health and appearance after three months of use.

This article outlines the evolving role of cosmetics in enhancing confidence and attractiveness, highlighting their ability to address skin and hair concerns with active ingredient serums.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

This review discusses the effects of estrogens on skin aging and highlights the potential benefits of estrogen replacement therapy and selective estrogen receptor modulators for improving skin health in postmenopausal women, but reports no new clinical findings.

In this study, serum from patients with alopecia areata or universalis did not affect hair growth in transplanted scalp skin grafts on nude mice, despite increased deposition of immunoreactants.

This study found that lower serum melatonin levels were associated with increased skin aging grades among individuals in Ulaanbaatar, suggesting melatonin loss may contribute to earlier skin aging.

This review explains that dysregulated sebum secretion and composition contribute to acne and impaired skin barriers while highlighting factors like diet and hormones affecting sebaceous activity, and identifies novel molecular targets and model systems for future therapeutic developments.

This review found a predominance of low serum zinc levels across various skin disorders, indicating possible value in further investigating zinc supplementation as an adjunctive therapy.

This study observed that among individuals with scalp seborrhoea, the scalp showed higher sebum levels, lower hydration, and compromised barrier function compared to other areas, and that a single shampoo application containing piroctone olamine significantly reduced sebum and oxidative stress markers.

In this study, a topical cream containing 3% lactic acid ferment lysate (VHProbi ® MixP) was found to significantly reduce sebum, porphyrin levels, and pore size, while increasing hydration and improving skin texture in participants with oily skin over a 60-day period.

The T-zone on the face has more androgen receptors and produces more oil than the U-zone.

In this study, finasteride doses as low as 0.2 mg per day significantly reduced both scalp skin and serum DHT levels in men with androgenetic alopecia.

In this study, researchers identified the antimicrobial peptide dermcidin in sebocyte lipid droplets, challenging the previous understanding of dermcidin as exclusively sweat-specific.

Reduced androgens linked to kinky hair disorder and hair loss; 5a-reductase inhibitors may help.

This study found that patients with acne vulgaris had higher serum IGF-1 levels and more intense FoxO1 and mTOR expression than controls, suggesting their role in acne pathogenesis.

In this laboratory study on mice, researchers found that both platelet-rich plasma and salmon DNA serum promoted wound healing, with platelet-rich plasma providing faster results due to its bioactive growth factors.

In this study, researchers established a model using Mongolia Sheep hair follicles to investigate growth mechanisms, noting that adding insulin and hydrocortisone helped maintain follicle shape during extended culture.

This study found a correlation between zinc levels in hair and serum, and alkaline phosphatase activity in acne phlegmonosa and alopecia areata patients.

This study found that a cosmetic formula containing 2% Orthosiphon stamineus leaf extract significantly reduced skin oiliness and pore size, showing better results than a formula with 1% zinc gluconate.

This study found that premature hair graying is strongly associated with a family history, Vitamin B12 deficiency, and hypothyroidism, with onset as early as 5 years in patients in Gurugram, India.

In this study, dogs fed Diet B with specific levels of dietary zinc and linoleic acid showed improved skin and hair coat conditions, evidenced by increased hair follicle growth and higher skin lipid scores.

This study found that MPZL3 knockout mice showed reduced dermal white adipose tissue and increased sebocyte proliferation, suggesting a regulatory role for MPZL3 in lipid metabolism balance between adipocytes and sebocytes.

In this study, altering the photoperiod in goats increased hormone concentrations and improved hair follicle development and skin antioxidant capacity, suggesting that short photoperiods may create favorable conditions for cashmere growth.

In this study, oral tofacitinib treatment led to significant hair regrowth and changes in skin and blood biomarkers in a patient with alopecia areata.

This study found that the BP-3 extract from Boesenbergia rotunda, rich in panduratin A, demonstrated strong anti-adipogenesis and lipolysis effects on preadipocyte cells at non-toxic concentrations, and when formulated into a serum reduced thigh circumference and improved skin firmness in a human trial.

This review found that autologous serum therapy, particularly its growth factor component in platelet-rich plasma, can be an effective dermatological treatment for wound healing, skin rejuvenation, acne scars, and androgenic alopecia while reducing the risks of hypersensitivity and infectious disease transmission.
