If you're looking to level up your skincare game, Alpha Hydroxy Acids (AHAs) might just be the secret weapon you need. Known for their ability to exfoliate the skin, fade dark spots, smooth texture, and boost radiance, AHAs are a favorite among dermatologists and skincare enthusiasts alike. But as powerful as they are, using them the wrong way can lead to redness, irritation, or even long-term skin damage.
Whether you’re dealing with dullness, uneven tone, acne scars, or early signs of aging, AHAs like glycolic acid and lactic acid can help—but only if introduced with care. One of the most common mistakes people make is overusing exfoliating acids without understanding how their skin will react. That’s where a proper routine comes in.
In this blog, we’ll walk you through how to safely and effectively incorporate AHAs into your skincare routine—without the sting. From choosing the right AHA for your skin type to avoiding common ingredient clashes, we’ve got everything you need to start exfoliating the smart way.
So if you're wondering how to get the glowing results of chemical exfoliation without compromising your skin barrier, keep reading. A radiant, smoother complexion could be just a few steps away.
What Are AHAs?
AHAs are water-soluble exfoliating acids that work by loosening the bonds between dead skin cells on the surface of your skin. Common AHAs include:
- Glycolic Acid – best for oily, acne-prone, and aging skin
- Lactic Acid – gentler, ideal for dry and sensitive skin
- Mandelic Acid – slow-penetrating, great for beginners and darker skin tones
- Malic and Citric Acids – mild AHAs often used in combination with others
Benefits of Using AHAs
- Removes dull, dead skin cells
- Unclogs pores and smooths texture
- Fades hyperpigmentation and acne scars
- Boosts collagen production over time
- Improves product penetration
Common Side Effects of Misusing AHAs
- Burning or stinging
- Flaky or dry patches
- Increased sun sensitivity
- Redness and inflammation
- Skin barrier damage with overuse
How to Incorporate AHAs Without Irritation
Follow these dermatologist-approved steps to introduce AHAs safely:
1. Start Slow (Especially for Beginners)
- Begin with low concentrations (5% or less).
- Use 1–2 times per week at night for the first 2–3 weeks.
- Gradually increase frequency only if your skin tolerates it well.
Tip: Start with lactic acid if your skin is dry or sensitive.
2. Use AHAs in Your Nighttime Routine
AHAs can increase your skin’s sensitivity to the sun. To minimize risk:
- Apply AHA products in the evening.
- Follow up with a gentle moisturizer to soothe and protect the barrier.
3. Avoid Mixing With Certain Actives
Do not combine AHAs with these in the same routine unless your skin is well-trained:
- Retinol or Retinoids
- Vitamin C (L-Ascorbic Acid)
- Other exfoliating acids (BHA, PHA)
- Benzoyl Peroxide
Instead, alternate them across nights or use them at different times of day.
4. Always Follow With SPF
AHAs thin the top layer of skin, making it more vulnerable to UV damage. Daily sunscreen (SPF 30 or higher) is non-negotiable when using AHAs—even if you're only applying them at night.
5. Hydrate and Repair the Skin Barrier
After using AHAs:
- Apply a hydrating serum with hyaluronic acid or panthenol.
- Use a barrier-repairing moisturizer with ceramides or peptides.
- Consider using niacinamide on off days to strengthen your skin and reduce inflammation.
6. Choose the Right Formulation
Depending on your skin type, you may want:
Skin Type | Ideal AHA | Why |
---|---|---|
Sensitive | Lactic acid, mandelic acid | Gentler and less irritating |
Dry | Lactic acid | Exfoliates while moisturizing |
Oily | Glycolic acid | Penetrates deeper to unclog pores |
Acne-prone | Glycolic acid | Reduces post-acne marks and improves texture |
7. Patch Test First
Apply the product to a small area (like behind the ear or on your jawline) for a few days. Look for any signs of:
- Redness
- Burning
- Peeling or sensitivity
If it passes, you’re safe to proceed!
Sample AHA Skincare Routine (Beginner Friendly)
Night Routine (2x per week):

Final Tips
- Avoid exfoliating scrubs while using AHAs.
- Don’t use AHA products on broken, inflamed, or irritated skin.
- Give your skin “rest days” between exfoliation.
