Exfoliating Acids Explained: AHA vs BHA vs PHA (2025 Guide)

🌿 Why Exfoliating Acids Matter

Our skin naturally sheds dead cells β€” but stress, dryness, and sun exposure slow that process.
Exfoliating acids keep your skin glowing, smooth, and even-toned by removing the dull layer on the surface.
But not all acids are the same.

🌸 β€œThe right acid transforms your skin. The wrong one irritates it.”


πŸ’§ AHA β€” Alpha Hydroxy Acids

Best for: Dry, dull, uneven skin

🌼 What It Does

  • Exfoliates the surface of the skin

  • Brightens dark spots

  • Smooths fine lines and texture

⭐ Common Types

  • Glycolic Acid

  • Lactic Acid

πŸ’‘ Who Should Use It?

If your skin looks dull, textured, or tight β†’ AHA gives instant glow.


🌿 BHA β€” Beta Hydroxy Acids

Best for: Oily, acne-prone skin

🌼 What It Does

  • Penetrates inside pores

  • Dissolves oil and blackheads

  • Reduces breakouts and congestion

⭐ Common Type

  • Salicylic Acid (the most popular BHA)

πŸ’‘ Who Should Use It?

If you struggle with clogged pores, breakouts, or blackheads β†’ BHA is your hero.


🌸 PHA β€” Polyhydroxy Acids

Best for: Sensitive or reactive skin

🌼 What It Does

  • Gently exfoliates without irritation

  • Hydrates while smoothing

  • Supports skin barrier

⭐ Common Types

  • Gluconolactone

  • Lactobionic Acid

πŸ’‘ Who Should Use It?

If your skin stings easily or gets red β†’ PHA = exfoliation without discomfort.

πŸ’• β€œThink of PHA as the sensitive skin version of AHA.”
