GlossaryUltraviolet B

type of ultraviolet radiation that causes sunburn and vitamin D production

Ultraviolet B (UVB) is a type of ultraviolet radiation with wavelengths between 280 and 315 nanometers. It is responsible for producing vitamin D in the skin but can also cause sunburn and contribute to skin cancer. In medical treatments, UVB light therapy is used to manage conditions like psoriasis and vitiligo by reducing inflammation and slowing down the overproduction of skin cells.

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

in Research/Science 4 upvotes 7 months 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.

community Tretinoin can make it worse!!!

in Chat 7 upvotes 1 year 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.
