In this study, researchers found that an injectable solution of low-molecular-weight hyaluronic acid and amino acids significantly improved skin rejuvenation and elasticity in the labia majora of post-menopausal women over 12 weeks, with a reported 25% or greater aesthetic improvement and high patient satisfaction.

This study found that Sinseon-yukza-hwan extract has strong antioxidative properties, effectively inhibiting free radical generation, which supports its potential use as a natural antioxidant.

Some sunscreen ingredients may be linked to hair loss, but more research is needed.

This research identified distinct attitudes influencing sunbathing and tanning salon use among female university students, with general attractiveness and skin aging concerns being strong predictors of sun exposure and protection intentions.

This study found that in mouse melanocytes, the cytoplasmic dynein complex component Dynlt3 is necessary for proper melanosome transport, acidity regulation, and effective transfer to keratinocytes, linking it to skin pigmentation processes.

This study found that a sunscreen with oxothiazolidine and δ-tocopheryl glucoside provided complementary oxidative protection, with immediate but brief effects from oxothiazolidine and prolonged effects from the slower-absorbing δ-tocopheryl glucoside.

In this study, kamishoyosangoshimotsuto extract improved skin moisture, texture, and brightness, as well as hair thickness and strength in women with skin and scalp hair problems over 24 weeks.

This study found that UVA blocker-containing sunscreens instantly reduced follicular fluorescence due to porphyrins in facial skin, with the effect lasting for a few hours, influenced by sunscreen amount and formulation.

This review synthesizes research on solar radiation's multifaceted effects on skin and recent advancements in sunscreen technology, including formulation, testing methods, and the use of AI, to inform future sun protection product development.

This study found that topical application of Sinsun-yukza-hwan extract significantly increased hair density and thickness in a mouse alopecia model and enhanced expression of growth-related genes.

This study compiles data on the microstructural and cytotoxic properties of nano physical sunscreens, emphasizing the need for a technology platform to assess nanomaterial characteristics due to their growing use in cosmetics.

This report describes two cases of alopecia totalis treated with turban psoralen and sunlight exposure, but it provides no clinical outcome results.

This study analyzed techniques to create the popular "sun-kissed" hair look on dark-to-medium blonde (Level 5–6) tones, concluding that a 2–3 level differential, targeted placement across three cranial zones, and acidic glossing are essential for optimal results.

This study synthesized a new organic sunscreen with broad photoprotective properties and demonstrated it to be non-toxic. The resultant cream, containing nanostructured lipid carriers, showed suitable application qualities and achieved a satisfactory SPF value of 16.

This review discusses the antioxidant and photoprotective potential of Polypodium leucotomos for use as a natural sunscreen ingredient and reports no new experimental results; further studies are recommended to evaluate its effectiveness.

In this study, combination therapy with cyclosporine and PUVA for severe alopecia areata resulted in a majority of patients showing only fair to poor responses, though some improvements were noted.

This study found that melanosomes extracted from human hair waste can effectively block UVA and UVB radiation when used as a natural UV filter in sunscreens, performing comparably to commercial UV filters and remaining stable in cosmetic formulations.

This study observed that melanoma survivors had higher odds of using sunscreen and seeking shade compared to cancer-free individuals, but their overall adherence to sun protection was less than expected given their elevated risk for new skin cancers.

This study enrolled nine patients to investigate the effects of oral psoralen and ultraviolet A therapy plus oral prednisolone for treating alopecia areata.

This study reported that regular mole examinations and UVR protection are crucial for skin cancer prevention, particularly for individuals with fair skin, inflammatory skin conditions, diabetes, and those on photosensitizing medications.

This study found that a polyherbal sunscreen cream, F4, containing Camellia sinensis, Vitis vinifera, and Silybum marianum extracts demonstrated strong antioxidant and photoprotective properties, similar to synthetic sunscreens.

This study found that emergency department visits due to sunburn were more prevalent and costly during the summer, with a higher likelihood among lower-income men from the South.

This review compiles epidemiological data on actinic keratoses and suggests promoting strategies like early diagnosis and photoprotection to prevent progression to skin cancer, but it reports no new clinical findings.

This review discusses various topics from the 62nd Annual Montagna Symposium on the Biology of Skin, focusing on the diverse effects of light on skin biology, and reports no new clinical results.

This study introduces the "skinspan" framework to promote skin longevity through sun protection, topical retinoids, and antioxidants as first-line care. It suggests lasers and emerging therapies as additional options but emphasizes the need for more randomized controlled trials to solidify the evidence base.

SesZen-BioTM improves skin health and reduces signs of aging.

This article offers a summary of the Seoul International Dermatology Symposium held in May 1995, but reports no new clinical findings.

This study developed an inexpensive method to provide initial data on both the photostability and toxicity of pure active principles and their photodegradation products.
