To date, Alpha Hydroxy Acids are some of the most beloved skincare ingredients. AHAs are a group of acids that include ingredients like glycolic acid, citric acid, mandelic acid, and lactic acid. Many of us who love skincare use glycolic because they reduce natural wrinkles and reverse sun damage.
As life goes on and as we are exposed to more sun, aged skin cells are replaced by newer ones at a slower rate. While aged and sun-damaged cells gradually get replaced at a slower rate, Alpha-hydroxy acids encourage them to shed at a faster rate. This process is known as “anti-aging.”
Many anti-aging products work by loosening the lipids or glue-like substances that hold the surface skin cells to each other. Once AHAs loosen the lipids binding the older or dead skin cells together, the cells can peel off gently. Then, voila! The skin underneath has a fresher, healthier look with a more even color and texture. With high concentration and long-term use, alpha hydroxy acids may also affect the deeper layers of our skin. This deep penetration aids in collagen, elastin (connective tissue that tightens skin) regeneration, and the softening of fine lines.
That’s what AHA product descriptions mean when they say “more supple-looking” skin can be attained by using it. However, there are some cons to consider. Some AHAs used in high concentrations can cause irritation and hyperpigmentation in people with Fitzpatrick phototype levels 4-6. While both mandelic and lactic acids are AHAs too, they are often considered gentler choices for hyperpigmentation and sensitive skin types. Depending on how sensitive the person’s skin is, glycolic acid can be irritating and lead to further hyperpigmentation.
Ascorbic acid is the antioxidant component in many skincare products. Antioxidants prevent UV damage or decrease UV damage by fighting free radicals, and likewise, they can help protect your skin’s collagen. However, the higher concentration of ascorbic acid, the higher the probability of irritation. The pH of ascorbic is between 2 and 3.5 while your skin’s pH is around 5.5. Therefore, if you have sensitive skin, using vitamin C as the last step of your skincare routine in the morning might be helpful. The products that you have already applied to your skin form a barrier and using vitamin C in the morning provides a fresh barrier against free radicals and pollution.
Ascorbic acid works for combination, oil, and dry as well as all Fitzpatrick phototypes. The thing to be most conscious about is the concentration of the acid.
All in all, retinoids and retinols work well on oily, combination, and dry skin. However, when retinol is applied to sensitive skin, there can be irritation.
