Pigmentary Disorders in Black Skin

    April 1989 in “ Clinics in Dermatology ”

    TLDR The argon gas-based cryotherapy effectively reduced keloid scars but caused some hypopigmentation and had a recurrence rate, especially in Afro-American patients.
    This study evaluated the effectiveness of an argon gas-based intralesional cryotherapy system for treating keloid scars in 25 patients with 30 keloid scars, including all Fitzpatrick skin types, over a 1-year follow-up. The treatment resulted in a significant 62% reduction in scar volume, improved scar quality, and alleviated pain and itching. However, 17% of scars recurred, particularly in Afro-American patients, and hypopigmentation was a notable issue. The argon gas-based system proved effective, especially for scars previously unresponsive to liquid nitrogen-based cryotherapy.

      A rigorous and extensive regimen for hair regrowth, including oral and topical minoxidil, finasteride, dutasteride, RU58841, various oils, supplements, and lifestyle changes, is discussed with skepticism and humor. The consensus is that such an extreme routine is impractical and potentially harmful, with no guaranteed results.
