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

Whether you’re interested in prescription-strength retinoic acid like Obagi® tretinoin products*, which are indicated for acne vulgaris, or a non-prescription alternative such as retinol, which can be found in the Obagi360 System, Obagi has a product for you. In addition, both tretinoin and retinol are offered in multiple strengths for your varying skin care needs. 

Only your skin care physician can determine what is best for your skin. Be sure to meet with him or her to plan a skin care regimen that will deliver the most effective results and address your concerns.

Weather extremes, such as wind or cold, also may be irritating to patients under treatment with tretinoin.

Unprotected exposure to sunlight, including sunlamps, should be minimized during the use of tretinoin, and patients with sunburn should be advised not to use the product until fully recovered because of heightened susceptibility to sunlight as a result of the use of tretinoin.
