Retinoids are commonly found in a variety of anti-aging products, yet they have one major downside: they are known to cause skin irritation and flaking . Despite this, many people are still using retinoid-based anti-aging products for the simple fact that they feel they have no other choice. Thankfully, ingredients like peptides and the amino acids that form them are taking center stage in the anti-aging skin care world, so you no longer have to choose between lines and wrinkles and flaky, irritated skin. Take a look at the main differences between retinoids and peptides and the benefits of upgrading your anti-aging skin care routine to include the latest and most effective ingredients.
What Are Retinoids?
First, let’s start with an overview of what retinoids are and why they are so popular in anti-aging creams. Retinoids are derivatives of vitamin A and work by increasing the turnover rate of skin cells . Because of this, topical retinoids, especially when used in highly concentrated prescription-strength formulas, cause the skin to flake and peel. For many people, this can also result in severe skin irritation, dryness, and itchiness. To help ease these symptoms, dermatologists typically recommend that you slowly introduce your skin to retinoids, which means that most people can only tolerate using these products once every two or three days at first. Men and women with very dry or sensitive skin may never be able to increase the frequency with which they use retinoids. In addition, retinoids are also believed to be harmful to developing fetuses, so women are advised to discontinue using products that contain this ingredient while pregnant or breastfeeding .
What Are Peptides?
Peptides are naturally-occurring substances that form when two or more single amino acids join together via peptide bonds to form a short chain. Chains of 50 or more amino acids are technically considered proteins rather than peptides . Along with the amino acids that create them, peptides are necessary components of all forms of life. They play vital roles in a wide range of functions within the human body, including the skin. In terms of anti-aging skin care, peptides are excellent ingredients because of these natural functions that they perform. A combination of the amino acids glycine, proline, and hydroxyproline, for example, is needed in order for the skin to produce the collagen proteins that give it its firm, youthful structure . Thus, by adding combinations of amino acids to the skin in the form of specially designed peptides, you can stimulate your skin’s natural collagen production for a smoother, more youthful complexion without any harsh side effects. In addition, because peptides and amino acids actually trigger protein production, the results that you get from using skin care products that contain these ingredients can have long-lasting effects. Another amazing benefit of using peptides and amino acid skin care products is that they don’t have to be limited to just your wrinkle creams. Look for these ingredients in your everyday products, too, like cleansers, moisturizers, and eye creams. Because peptides and amino acids don’t have adverse side effects like retinoids, you can use them throughout the day and in a variety of products. In fact, amino acids are considered so safe that they have even been approved for use on baby skin .
The Bottom Line
Although retinoids have long been used to treat acne and wrinkles, peptides and amino acids are quickly surpassing these harsh ingredients and becoming the anti-aging all-stars of the future. No matter your skin type, condition, or age, you can benefit from using peptides and amino acids in your skin care products, because these substances are already naturally present throughout your body.
