How do retinoids assist in the treatment of acne?

Retinoids assist in the treatment of acne primarily by promoting cell turnover. This process involves the shedding of dead skin cells from the surface of the skin, which helps to prevent them from clogging the pores. Clogged pores are a primary factor in the development of acne, as they can lead to the formation of comedones (blackheads and whiteheads) and inflammation. By increasing the rate at which skin cells renew and shed, retinoids can help to keep the pores clear and reduce the likelihood of acne breakouts.

Additionally, retinoids have anti-inflammatory properties and can help in reducing the overall redness and swelling associated with acne lesions. This makes them a versatile and effective choice for acne treatment, as they address multiple facets of the condition simultaneously.

Hydration of the skin is not a primary function of retinoids; instead, they can sometimes lead to dryness or irritation, especially in the initial phases of treatment. Increasing oil production is counterproductive in acne treatment, as excess oil can contribute to clogged pores, and lightening skin pigmentation is a different dermatological concern often addressed with other types of treatments such as certain acids or light therapies.
