AHA vs BHA: Meaning, Types & Benefits
If youâve ever wondered âWhat are AHA & BHA and how do they improve skin?â, youâre in the right place! From smoothing rough patches to keeping breakouts at bay, AHA skincare and BHA exfoliants are like the superheroes of your beauty routine. However, with so many acids, serums, peels, and toners available, the distinction between AHA and BHA can feel confusing.
In this guide, weâll break down what AHA and BHA really are, their benefits, the difference between them, and the best AHA and BHA products you can add to your routine. Whether youâre curious about that glow-from-within skin effect or looking for real results like smaller pores, fewer breakouts, or fading dark spotsâweâve got all the deets.
What is AHA & Its Types?
AHA stands for Alpha Hydroxy Acidâa group of water-soluble acids naturally derived from fruits, milk, and sugarcane. They mainly work on the surface of the skin by loosening up dead skin cells, resulting in smoother, brighter, and more even-toned skin. Think of it as a fresh resurfacing treatment in your daily skincare!
Here are the most popular types of AHA:
-
Glycolic Acid
Known as the âstar playerâ of AHAs, glycolic acid has the smallest molecular size, which means it penetrates deeper into the skin. This makes it ideal for treating dark spots, uneven tone, and fine lines while accelerating cell turnover.
-
Lactic Acid
A gentler AHA, derived from milk. Unlike glycolic acid, it not only exfoliates but also hydrates, making it excellent for dry or sensitive skin. Itâs often recommended for beginners dipping their toes into AHA skincare.
-
Mandelic Acid
Larger molecules = slower penetration. This is why mandelic acid is ideal for acne-prone or sensitive skin; it works steadily without being harsh, while also helping to improve texture and pigmentation.
-
Citric Acid
Extracted from citrus fruits, citric acid acts as a mild exfoliant but also doubles as an antioxidant. It helps brighten dull complexions while protecting the skin from free-radical damage.
-
Malic Acid
Found in apples, malic acid is often used in combination with other AHAs. It enhances skin radiance, provides mild exfoliation, and preps skin to better absorb other skincare ingredients.
In short: AHA for skin = glow, smoothness, and radiance!
What is BHA & Its Types?
BHAs, or Beta Hydroxy Acids, are oil-soluble, meaning they can go deeper, past the skinâs surface, and clean out pores filled with oil, dirt, and gunk. This is why BHA skincare shines in treating blackheads, whiteheads, and acne.
Types of BHA:
-
Salicylic Acid
The OG of BHAs! Salicylic acid exfoliates inside the pore lining, dissolving excess sebum and preventing acne formation. Itâs anti-inflammatory and antibacterial, making it a holy grail for oily and acne-prone skin.
-
Betaine Salicylate
A softer alternative to traditional salicylic acid. While it exfoliates similarly, itâs less irritating, making it well-suited for sensitive or dry skin types that still deal with congestion or breakouts.
In short: BHA = deep cleansing, oil control, and acne reduction.

How to Use AHA & BHA Together
Can you use AHA and BHA together?
Yes, but be careful! Since both are exfoliants, layering them daily may irritate. Instead:
-
Try alternating themâAHA at night (for brightness) and BHA in the morning (for breakouts).
-
Or, use products that combine safe concentrations of both.
