High Purity High Quality Cosmetic Materials Isotretinoin

I sotretinoin (INN), also known as 13-cis retinoic acid, is an oral pharmaceutical drug primarily used to treat cystic acne. Rarely, it is also used to prevent certain skin cancers (squamous-cell carcinoma), and in the treatment of other cancers. It is used to treat harlequin-type ichthyosis, a usually lethal skin disease, and lamellar ichthyosis. It is a retinoid, meaning it is related to vitamin A, and is found in small quantities naturally in the body. Its isomer, tretinoin, is also an acne drug.

I sotretinoin is primarily used as a treatment for severe acne. The most common adverse effects are a transient worsening of acne (lasting 2-3 weeks), dry lips (cheilitis), dry and fragile skin, and an increased susceptibility to sunburn. Uncommon and rare side effects include: muscle aches and pains (myalgias), and headaches. I sotretinoin is known to cause birth defects due to in utero exposure because of the molecule's close resemblance to retinoic acid, a natural vitamin A derivative which controls normal embryonic development.
