What medication is commonly used to treat acne and sun-damaged skin?

Retinoic acid is often used to treat acne and sun-damaged skin due to its ability to promote cell turnover and improve skin texture. As a retinoid, it enhances the skin’s natural processes by increasing the rate of skin cell renewal and helping to unclog pores, thereby reducing acne breakouts. Additionally, it has the capacity to address issues associated with sun damage, such as fine lines, uneven pigmentation, and rough texture.

While other options, such as salicylic acid and benzoyl peroxide, are effective treatments for acne, they function differently. Salicylic acid works as a chemical exfoliant that helps to keep pores clear, and benzoyl peroxide is an antibacterial agent that kills acne-causing bacteria. Hydroquinone, on the other hand, is primarily used for hyperpigmentation and not specifically for treating acne, making retinoic acid the most suitable choice for addressing both acne and sun-damaged skin.
