While it cannot remove tan, it can also lighten your skin tone, when used long-term. Read on to learn all about tretinoin, its benefits and how to use it.

What is tretinoin?

Tretinoin is a derivative of vitamin A and is used in dermatology for various skin conditions. โ€œIt is a prescription-strength medication which is applied to the skin. It tackles acne and sun damage, reducing wrinkles and fine lines,โ€ explains dermatologist Priyanka Kuri. It is also used to treat acne and helps pimples to heal quickly.

What does tretinoin do?

Tretinoin helps promote the growth of skin cells. It is useful in lightening your skin and also promotes the growth of new skin replacing old skin cells. The benefits of tretinoin include the reduction of wrinkles, acne, discoloration, as well as age spots when used for at least three to four months.

Tretinoin vs retinol: What is the difference?

Tretinoin and retinol are both vitamin A derivatives, but tretinoin is much stronger. โ€œRetinol converts to a weaker form of retinoic acid in your skin, making tretinoin work faster and bring stronger results,โ€ explains Dr Kuri. Retinol is a natural version of vitamin A, while tretinoinย  is a synthetic one. Retinol is mild and doesnโ€™t irritate the skin, however, tretinoin is much stronger. Therefore, if you have sensitive skin, then you should be careful while using tretinoin.
