Did you mean Ultraviolet A radiation damage?

GlossaryUltraviolet A damage

harm from deep-penetrating UVA rays causing skin aging and cancer

Ultraviolet A (UVA) damage refers to the harm caused by UVA radiation, a type of ultraviolet light from the sun that penetrates deep into the skin. This damage can lead to premature aging, DNA mutations, and an increased risk of skin cancer. UVA rays are less intense than UVB rays but are more prevalent and can penetrate through clouds and glass, making them a significant concern for long-term skin health.

community Evolution theory: AGA is your body trying to reduce the risk of prostate cancer by exposing your scalp to more UV

in Research/Science 3 months ago

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

community Tretinoin can make it worse!!!

in Chat 7 upvotes 2 years ago

Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.

community What About Phytosterol Alternatives - Rice Bran Oil - Natural DHT Blockers

in Research/Science 4 upvotes 1 year ago

The conversation discusses natural DHT blockers like rice bran oil, which may reduce 5α-reductase activity similarly to Minoxidil and Dutasteride. One user argues that finasteride is more reliable and effective than natural alternatives.
