Ingredient Feature: Retinoids
Retinol, retinal, retinoid, retinoic acid, retinyl palmitate, tretinoin... What do they all mean and what are the differences among them? In this blog we take a closer look at the differences between the two most common retinoids: retinol and all-trans retinoic acid.
Retinoids are derived from vitamin A. While the name comes from its relationship to the production of pigment in the retina of our eye, retinoids are more commonly known for their use in skin care and the tremendous benefits they offer for the skin. But what exactly do they do and how do you know which retinoid is right for you?
The first retinoid— all-trans retinoic acid (its chemical name) or tretinoin (generic name)—was approved (under the brand name Retin-A) almost 40 years ago as a prescription acne treatment. Dermatologists later found that it not only treated acne vulgaris, but it also helped to treat fine facial wrinkles. Now, there are multiple prescription-strength versions of tretinoin approved by the FDA for acne and some for fine facial wrinkles. Several other retinoid derivatives have also been developed for other skin diseases.
Since its introduction into skin care, the market has been saturated with various retinoid creams, gels and the like, along with cosmetic versions with related molecules. Deciding on the right one for you can be confusing.
Here’s what you should know: different retinoids are offered in multiple forms and strengths – both prescription and non-prescription and, depending on the particular retinoid in the family, they are recommended for different uses.
Here are some guidelines to help you understand the effectiveness and length of time before you may see results with the two primary types of retinoids available in skin care:
- Tretinoin, or retinoic acid, requires a prescription from your skin care physician. It is used to treat acne, and in different cream bases can be used to treat fine lines and wrinkles, rough skin, and mottled hyperpigmentation.1 Experts believe it helps to speed up the skin’s natural exfoliation process and improve skin’s laxity. As a prescription-strength product, this topical treatment has expected side effects including redness, peeling, dryness and flaking of the skin.
- Retinol is an ideal solution for those interested in a topical retinoid that does not require a prescription. Retinol refines the appearance of skin texture and tone for clearer-looking skin. You can learn more about Obagi’s line of retinol here.
