This narrative literature review by Lustrao examines the existing research on six botanical ingredients in their Hair Regrowth Oil, finding varied evidence levels and highlighting rosemary oil's strong human clinical support for hair growth compared to minoxidil.

This exploratory pilot study reported that using a 2% Oleosome-FGF-2 fusion extract scalp serum twice daily for 84 days in women with telogen effluvium and brittle hair improved hair density, anagen/telogen ratio, hair shaft thickness, and scalp hydration compared to a placebo.

This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.

This review highlights that Trigonella foenum-graecum L. (fenugreek) shows promise as a versatile plant-based ingredient in cosmetics due to its phytochemicals, which offer benefits for skin and hair care, although further research is necessary for robust validation.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

In this study, a 90-day course of a plant-based supplement significantly improved hair density, skin hydration, and nail growth among participants with dermatological concerns, while also reducing hair fall and pigmentation, without adverse effects.

In this study, a systematic review highlighted the potential of exosomes in cosmetics and regenerative medicine for improving skin rejuvenation and addressing aging, while also pointing out existing challenges such as regulatory hurdles and the need for more clinical validation.

This review reports that collagen peptides consistently provide modest improvements in skin hydration and elasticity and varying benefits for body composition and cardiometabolic markers, although effects on blood sugar control are less consistent; variations in source, dose, and study definitions limit generalizability.

This review reports that collagen peptides provide consistent, modest benefits for skin hydration and elasticity, with variable effects on body composition and cardiometabolic risk markers, though some outcomes remain inconsistent due to trial heterogeneity.

This study suggests that APC collagen peptides may accelerate hair growth and promote overall hair health by enhancing cellular proliferation and activating specific signaling pathways in human and mouse models.

This study found that in healthy adult women, a collagen and antioxidant-rich treatment significantly improved skin elasticity, hydration, texture, and reduced wrinkles and hair fall over 56 days compared to a placebo, indicating its efficacy and safety.

This study observed that using ultra-high-frequency ultrasound with 70 MHz probes effectively assessed the distribution of hyaluronic acid fillers and improvements in nasolabial fold wrinkles, with significant changes in dermal thickness and wrinkle scores maintained 24 weeks after treatment.

This review found limited support for oral vitamin C and E in treating pigmentary disorders like chloasma, inflammatory conditions, and pressure wounds, with evidence constrained by small, varied studies.

This study found that the ThriveCo Anti-Dandruff Pre-Shampoo Treatment, containing ZenscalpinTM, significantly reduced dandruff by 54.79% after 8 days and improved scalp health, with most participants reporting reduced flaking, dryness, and itchiness, and no noted adverse events.

This review highlights that injectable biostimulatory agents like poly-L-lactic acid, polycaprolactone, and calcium hydroxyapatite are effective in regenerative aesthetics by enhancing collagen production, stimulating adipogenesis, and improving dermal quality, although further research is needed to standardize protocols and confirm long-term safety and efficacy.

This review discusses the properties and bioextraction methods of chitin and chitosans, emphasizing their potential use in eco-friendly cosmetic manufacturing and reports no new experimental findings.

This study found that nanoemulsions of different sizes vary in their ability to penetrate skin layers, with smaller sizes aiding transdermal delivery and potential applications in transcutaneous immunization.

Various treatments can improve post-acne scars, but results vary.

The researchers found that plant extracts from Papaver rhoeas L., Clitoria ternatea L., and Carthamus tinctorius L. are effective natural cosmetic dyes, offering intense and stable colors without cytotoxicity.

This review discusses the potential benefits and biological activities of MSC secretome for various skin applications, but it reports no new clinical results.

This study found that bioactive extracts from goat placenta, particularly when delivered via dissolving microneedles, enhanced fibroblast proliferation and skin regeneration without being toxic to skin cells, suggesting a promising dermal application for improving skin health.

This study observed that earlier-passage keratinocyte cultures led to superior hair follicle neogenesis in dermal-epidermal composites grafted onto immunodeficient mice, suggesting their potential utility in studying human hair follicle development.

VYC-12L effectively improves skin smoothness, reduces fine lines, and boosts hydration.

This study found that incorporating a block copolymer significantly alters the size and morphology of niosome drug delivery systems made of non-ionic surfactants and cholesterol, affecting their stability.

In this study, SNPs in genes affecting skin pigmentation were linked to each skin type's unique response to environmental stress, suggesting potential for personalized skin care products.

This study found that long-term use of a home-use LED device for neck skin rejuvenation significantly improved wrinkle appearance and skin biophysical parameters without affecting thyroid function or morphology after 16 weeks of daily use.

In this study, Doublebase gel was more effective in maintaining and increasing skin hydration compared to Aqueous cream BP, with higher patient satisfaction and preference for future use.

In this review, researchers explored the potential of exosomes in cosmetics, skincare, tissue regeneration, and dermatological treatment, noting their promising ability to modulate cellular environments, potentially improving skin health and treating various skin conditions.

This study found that WWOX deficiency in mice leads to impaired skin development, reduced epidermal thickness, and significant hypothermia due to disrupted cell proliferation and homeostasis.

In this study, the combination of ECM-C with microneedle and radiofrequency treatments improved periorbital wrinkles, skin elasticity, and thickness more effectively than ECM-C with microneedles alone, but subjective evaluations showed no significant differences.
