What Are Retinoids?
Retinoids are topical or oral (ex. Accutane) products, chemically related to Vitamin A, that help with acne, anti-aging, and hyper-pigmentation.
From what I understand, retinoids work by normalizing skin cell growth and function, helping to improve the the way your skin sheds and renews itself. By binding to specific receptors in your skin, retinoids activate or inhibit certain cell activities, either stimulating collagen production and/or preventing the hyperproliferation of keratinocytes (skin cells in your epidermis), which keeps your pores clean and improves skin conditions such as acne and psoriasis. [1]
Long term retinoid use basically "changes" your skin by affecting gene expression and causing new skin cells to divide and function at their best. When used consistently, retinoids can keep your skin clear, even out skin tone, and repair and prevent pre-mature aging. This skin-changing factor, along with other exfoliating and anti-inflammatory properties, make retinoids the gold standard for acne and anti-aging treatments. However, those with clear, wrinkle-free skin can also use retinoids as a preventative measure to help preserve their skin in the long run.
Even though retinoids are great products, they do not work miracles! While they can help improve the appearance of wrinkles and stimulate collagen production in your skin, they cannot completely stop the aging process. Retinoids also come with their fair share of irritation and may not be tolerated by everyone.
Retinoids are available both over-the-counter and via prescription. Stronger retinoids, however, must be prescribed by your dermatologist or medical practitioner. Retinol, retinaldehyde, and tretinoin are all classified as retinoids. To learn more about them and their differences, check here.
