AHA - BHA

What Are AHA and BHA?

In skincare, the most commonly used chemical exfoliants are AHAs (Alpha Hydroxy Acids) and BHAs (Beta Hydroxy Acids). Both help remove dead skin cells, accelerate cell turnover, and reveal a smoother, brighter complexion. However, they work differently and target different skin concerns.

What Are AHAs?

AHAs are water-soluble acids that work mainly on the skin surface. The most common AHA types include:

• Glycolic Acid
• Lactic Acid
• Mandelic Acid
• Citric Acid
• Malic Acid

Benefits of AHAs

• Smooths and exfoliates the skin surface
• Evens skin tone
• Helps reduce hyperpigmentation
• Softens fine lines and wrinkles
• Adds radiance and glow

Best For

• Dry skin
• Normal skin
• Hyperpigmentation
• Dull or rough skin texture

What Are BHAs?

BHAs are oil-soluble acids that penetrate deep into the pores to dissolve sebum buildup. The most widely used BHA is:

• Salicylic Acid

Benefits of BHAs

• Deeply cleans clogged pores
• Reduces acne and blackheads
• Controls excess oil
• Minimizes inflammation and redness

Best For

• Oily skin
• Combination skin
• Acne-prone skin
• Blackheads and enlarged pores

Differences Between AHA and BHA

Can You Use AHA and BHA Together?

Yes, but carefully. Overuse can weaken the skin barrier. The safest method is alternating usage (e.g., AHA one night, BHA the next).

Conclusion: Which One Should You Use?

• For pigmentation, dullness, aging: Choose AHA
• For acne, blackheads, oiliness: Choose BHA
• For both concerns: Alternate AHA and BHA
