Malic Acid

Explained

Malic Acid is an acid with both AHA and BHA properties, but is considered an AHA because its AHA properties are stronger.

It can be naturally found in unripe fruit and especially apples (its name from the latin word "malum", meaning apple!).

How it works

Like other AHAs, malic acid gently removes the top layer of dead skin cells to reveal smoother, brighter skin underneath.

Though it’s considered milder and less potent than glycolic or lactic acid, it can help improve:

  • Skin texture
  • Uneven tone
  • Fine lines and wrinkles
  • Acne blemishes

Due to its larger molecular structure, it penetrates the skin more slowly and is often used in combination with other AHAs to enhance their overall effectiveness.

Malic acid often plays a role in balancing a product’s pH and is usually included in small amounts (around 1-2%) as a supporting exfoliant.

As with all exfoliating acids, you should wear sunscreen daily when using malic acid to protect your newly resurfaced skin.

Fun fact: Malic acid is the compound responsible for the tart flavor of apples and other sour fruits.

While research on malic acid is limited compared to glycolic or lactic acid, it’s still a safe and mild exfoliant.
