Beta all trans retinoic acid is a chemical compound that plays a crucial role in various biological processes. This substance is commonly used in medical and cosmetic applications due to its potential therapeutic effects. Synonyms for beta all trans retinoic acid include tretinoin, isotretinoin, and retinol. These terms are often used interchangeably to refer to this compound. Tretinoin, a popular treatment for acne and other skin conditions, acts by reducing sebum production and speeding up skin cell turnover. Isotretinoin, on the other hand, is mainly used for severe acne treatment. Retinol, a less potent form, is widely available in over-the-counter skincare products and is often used for its anti-aging properties.
