Retinol Vs. Retinoids for Acne

Retinoid prescription medications can provide a solution to the blackheads, red bumps and inflammation associated with acne flare-ups. These products are derived from vitamin A, or retinol.

Identification

The word "retinoid" can refer to vitamin A (retinol) or to a substance with a similar chemical structure, such as a derivative of vitamin A, according to the Mayo Clinic.

Types

Retinoids can be oral tablets or topical creams, gels and serums. They are considered to be a type of product rather than a single ingredient.

Function

Retinoids fight acne by increasing the frequency of cell turnover and helping prevent the pores on the face from becoming plugged with dead skin cells, dirt and oil, according to the Mayo Clinic.

Oral Retinoids

Oral isotretinoin is a retinoid that reduces sebum secretion (excess oil on the face). It also fights infection and reduces inflammation that is often associated with acne, according to Acne Science.

Expert Insight

According to Acne Science, a 50 percent reduction in pustules may be observed after two to four weeks of treatment with oral isotretinoin. Users also may begin to see results with other retinoids, such as tretinoin, after two weeks, according to Ortho Dermatologics.
