A direct derivative of vitamin A, it is highly effective in stimulating cell regeneration and improving skin structure at the cellular level. Tretinoin is widely used to treat acne, hyperpigmentation, melasma, acne scars, and premature wrinkles, making it one of the most effective ingredients in medical products such as tretinoin cream, tretinoin acne treatment, and tretinoin for hyperpigmentation. Treatment is provided under the supervision of a specialist at Nadara Dermatology, Laser, and Cosmetic Center to achieve the best and safest results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is Tretinoin?<\/h2>\n\n\n\n<p>Tretinoin is the acidic form of vitamin A (retinoic acid), and it works to regulate the cell division cycle. <a href=\"https:\/\/ar.wikipedia.org\/wiki\/%D8%AE%D9%84%D9%8A%D8%A9_%D9%82%D8%B1%D9%86%D9%8A%D8%A9\" target=\"_blank\" rel=\"noopener\">corneal cells<\/a> Within the skin, it exfoliates the surface layers and stimulates collagen production. Compared to commercial retinol products, tretinoin boasts a higher potency and proven clinical results, making it the preferred medical choice in professional dermatological treatments.<\/p>\n\n\n\n<p
