Skin Care Basics - The Benefits of Alpha-hydroxy Acids (AHAs)

Skin Care Basics - The Benefits of Alpha-hydroxy Acids (AHAs)
Alpha-hydroxyl Acids (AHAs)


Our skin has a natural ability to exfoliate dead skin cells and does so daily. Unfortunately, this process slows down with age, which can lead to an accumulation of dead skin cells, leaving skin appearing dull and uneven.

AHAs dissolve the upper layer of skin cells by weakening the cellular “glue” that holds dead skin cells together, encouraging exfoliation and triggering skin repair.


AHAs have a number of proven skin benefits.

AHAs remove dead skin cells, revealing healthy, younger skin cells, resulting in a brighter complexion and more even skin tone. This increase in cell turnover is also effective in treating sun-damaged skin, hyperpigmentation, and melasma.

AHAs trigger collagen regeneration, thickening the outer skin layers. This works to firm and tighten skin. minimize fine lines/wrinkles, and fade blotches. (When combined with a retinol, these results can be even more dramatic, but we’ll save that for another blog...)


Many of my clients with dry or sensitive skin get nervous when they hear the word “acid“. Have no fear! Even those with dry or sensitive skin can benefit from regular use of a quality AHA product with proper pH balance.

AHAs may actually be a better choice to exfoliate sensitive skin because they are less likely to irritate then manual exfoliation. AHAs are gently applied to the skin, no need to scrub. AHAs can also be effective for dry skin. By removing the outer layer of dead skin cells, healthy skin cells become more receptive to the skin care products you apply. Regular AHA use, combined with appropriate product, can significantly increase your skin’s moisture factor.

While there are a number of AHAs, the two most commonly used in skin care are Glycolic Acid and Lactic Acid. Glycolic Acid is considered to be the most powerful because it has the smallest molecular size of all AHAs. The smaller the molecule, the deeper it is able to penetrate skin layers.

When beginning an AHA regimen, it is important to “start low and go slow”.
Start low - choose a product with a lower concentration of acid to start. Over time, and under the supervision of your skin care provider, you can gradually increase the concentration of your product for added benefits.

Go slow - don’t overdo it! Start your AHA routine only 1-2 times per week, giving your skin plenty of time in between treatments to rest and repair. You can gradually work up two more frequent use. I typically recommend an every other day regimen for my patients, using AHAs twice daily on “active“ days, with “rest“ days in between.

You can add an AHA right into your regular skincare routine. Apply your AHA after cleansing, and follow with serum and/or moisturizer. Don’t forget sun protection! Use of AHAs can make your skin more susceptible to sun damage, so don’t forget your daily sunblock!

Carin Nielsen, MD Integrative Medicine I use an Integrative/Functional Medicine approach with my patients to treat a variety of chronic medical conditions, as well as general wellness and healthy aging. Treating symptoms simply by prescribing medication as a “band-aid” does not address the underlying factors that contributed to your problems in the first place, and is not likely to provide lasting results. My approach involves getting "under the surface” to find and correct underlying imbalances, and providing treatment options that go beyond the prescription pad.
