| Before and After Skin after using AHA/BHA |
If you’re looking to elevate your skincare routine, chemical exfoliants like AHAs (Alpha Hydroxy Acids) and BHAs (Beta Hydroxy Acids) are powerful ingredients to consider. AHAs and BHAs help remove dead skin cells, refine texture, treat acne, and brighten the skin. This guide will explore the benefits of AHAs and BHAs, how they work, and tips for choosing the best products.
What Are AHAs and BHAs?
AHAs and BHAs are types of chemical exfoliants used in skincare to promote smoother, brighter skin. Unlike physical exfoliants (like scrubs), these acids work by dissolving the bonds holding dead skin cells together, leading to a gentle exfoliation without harsh scrubbing.
1. AHAs (Alpha Hydroxy Acids) AHAs are water-soluble acids derived from natural substances like fruits and milk. They exfoliate the surface layer of the skin, making them ideal for addressing concerns like dullness, fine lines, and uneven texture. Common AHAs include glycolic acid, lactic acid, mandelic acid, and citric acid.
2. BHAs (Beta Hydroxy Acids)
Unlike AHAs, BHAs are oil-soluble, which allows them to penetrate deeper into the skin. They work well for oily or acne-prone skin by unclogging pores and reducing sebum production. The most common BHA used in skincare is salicylic acid.
Key Benefits of AHAs and BHAs
1. Refine Skin Texture
Both AHAs and BHAs exfoliate dead skin cells, leaving your skin smoother and softer. AHAs are great for treating rough skin, while BHAs can help with bumps and clogged pores.
2. Brighten Skin Tone
AHAs, especially glycolic and lactic acid, are known for brightening dull skin. By encouraging cell turnover, AHAs reveal fresher skin beneath and reduce the appearance of dark spots and hyperpigmentation.
3. Prevent and Treat Acne
Salicylic acid (a BHA) is ideal for acne-prone skin. It penetrates the pores to remove excess oil and reduce breakouts, preventing blackheads, whiteheads, and other forms of acne.
4. Reduce Fine Lines and Wrinkles
Regular use of AHAs can help minimize fine lines and wrinkles by boosting collagen production. This makes them popular in anti-aging skincare routines.
5. Boost Hydration
Surprisingly, certain AHAs, such as lactic acid, have hydrating properties that draw moisture to the skin, making them suitable even for those with dry skin.
How to Use AHAs and BHAs in Your Skincare Routine?
Introducing AHAs and BHAs into your routine requires careful attention to avoid irritation. Here’s a simple guide:
- Choose Your Acid Wisely: AHAs are ideal for dry or sensitive skin, while BHAs work better for oily, acne-prone skin.
- Start Slowly: Begin with lower concentrations (5-10% for AHAs and 1-2% for BHAs) and use them 2-3 times a week. Gradually increase frequency as your skin builds tolerance.
- Apply After Cleansing: Use AHAs or BHAs after cleansing and before moisturizer in your skincare routine. Follow up with a hydrating serum and moisturizer.
- Pair with Sunscreen: AHAs and BHAs increase sun sensitivity, so it’s essential to wear SPF during the day to protect your skin from UV damage.
Different Types of AHAs and BHAs
1. Glycolic Acid (AHA)
Derived from sugarcane, glycolic acid is the most effective AHA for promoting cell turnover and brightening the skin. It’s great for uneven texture and dullness.
2. Lactic Acid (AHA)
Derived from milk, lactic acid is a gentler AHA that provides exfoliating and hydrating benefits, making it ideal for sensitive skin types.
3. Mandelic Acid (AHA)
Mandelic acid is derived from almonds and has larger molecules, making it less irritating than other AHAs. It’s excellent for sensitive or reactive skin.
4. Salicylic Acid (BHA)
Salicylic acid is a BHA known for penetrating deep into pores, making it a popular choice for treating acne, blackheads, and oily skin.
Common Myths About AHAs and BHAs
Myth 1: AHAs and BHAs are too harsh for sensitive skin
While strong concentrations can be irritating, there are plenty of gentler options like lactic acid and mandelic acid, which are suitable for sensitive skin.
Myth 2: You Can’t Use AHAs and BHAs Together
AHAs and BHAs can be combined in a skincare routine, but start with lower concentrations and use them on alternating days to prevent over-exfoliation.
Myth 3: Chemical Exfoliants Will Make Your Skin Peel
Not everyone experiences peeling with AHAs and BHAs. Some mild flaking can occur when you first start using them, but this usually subsides as your skin adapts.

Yes, you can use them together, but it’s best to alternate days or layer them carefully, especially if you’re new to exfoliating acids.
2. Should I use AHAs and BHAs daily?
If you’re new to chemical exfoliants, start with 2-3 times a week and gradually build up to daily use if your skin tolerates it well.
