Tretinoin is a topical medication derived from vitamin A, also known as all-trans retinoic acid. Tretinoin accelerates the turnover of skin cells, which helps unclog pores and prevent the formation of acne. It also stimulates the production of collagen, which improves skin firmness and elasticity.

It helps to exfoliate as it promotes the shedding of dead skin cells, leading to smoother and brighter skin. Tretinoin is available in various formulations, including creams and gels, with different strengths prescribed based on skin type and condition. Higher strengths are available by prescription, typically for acne treatment and more severe skin concerns. It is important to remember that it can increase sensitivity to sunlight, so it’s essential to use sunscreen daily and avoid prolonged sun exposure.
