    TLDR The laser treatment effectively improved facial pigmentation with no major side effects.
    This case report documents the successful treatment of facial partial unilateral lentiginosis (PUL) in a female patient using a 532-nm Nd:YAG fractional picosecond laser (FPL). The patient underwent four treatment sessions at four-week intervals with a 9 mm high coverage handpiece micro lens array. The treatment was well-tolerated and resulted in significant improvement in pigmentation without significant side effects. The study concludes that the 532-nm Nd:YAG FPL is an effective and well-tolerated option for treating facial PUL.

Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.

      The user started using minoxidil and finasteride about four months ago for hair thinning but is unsure if it's working, as they haven't noticed new hair growth and feel their hair has thinned. Other users advise patience, suggesting that significant results may take 12 to 24 months, and recommend consistency in treatment.

      Switching from finasteride to dutasteride and back to finasteride led to gynecomastia and fatigue, likely due to hormonal imbalances. Suggested treatments include Tamoxifen, Raloxifene, or low-dose Anastrozole, with a recommendation to test testosterone and estradiol levels.
