Malic Acid in Skincare: The Overlooked AHA With Big Benefits

When it comes to skincare acids, glycolic and lactic often steal the spotlight. But hidden among the family of alpha-hydroxy acids (AHAs) is malic acid—a gentle yet effective ingredient that deserves more attention. Derived from fruits like apples and pears, malic acid combines the exfoliating power of AHAs with the hydrating qualities of humectants, making it a versatile addition to modern skincare routines.

What Is Malic Acid?

Malic acid is a naturally occurring AHA found in many fruits, particularly apples (in fact, the Latin word malum means apple). Like other AHAs, it works by loosening the bonds between dead skin cells, allowing them to shed more easily. This process reveals smoother, brighter, and fresher-looking skin beneath.

What makes malic acid unique is its dual action: it exfoliates while also attracting moisture to the skin. Compared to glycolic acid, it’s milder and penetrates more slowly, which makes it less irritating and suitable for sensitive or beginner users.

Type of Ingredient: Alpha-hydroxy acid (AHA) and mild humectant

Main Benefits: Provides gentle exfoliation, improves skin texture and tone, brightens dullness, hydrates by attracting moisture, supports anti-aging, and helps unclog pores.

Who Should Use It: Suitable for most skin types, but especially helpful for those with sensitive skin or beginners who may not tolerate stronger acids like glycolic.

How Often Can You Use It: Start 1–2 times per week in the evening; can be increased gradually depending on tolerance and skin needs.

Works Well With: Hydrating and barrier-strengthening ingredients such as hyaluronic acid, glycerin, niacinamide, and ceramides. Often paired with other AHAs for boosted results.

Don’t Use With: Other strong exfoliants or retinoids in the same routine, as layering too many actives may cause irritation. Always pair with sunscreen during the day.

Benefits of Malic Acid for Skin

• Gentle Exfoliation: Smooths out uneven texture and helps reduce dullness by removing dead skin cells.

• Brightening Effect: Helps improve uneven tone and fade mild pigmentation over time.

• Hydration Boost: Acts as a humectant, drawing water into the skin and keeping it plump and supple.

• Anti-Aging Support: Encourages cell turnover, which can soften fine lines and keep skin looking youthful.

• Acne-Friendly: By unclogging pores and reducing buildup, malic acid can help minimize breakouts.

• Synergy with Other Ingredients: Often used in combination with stronger acids (like glycolic or lactic) to enhance effectiveness without overwhelming the skin.

Possible Drawbacks

Malic acid is generally well tolerated, but there are a few things to note:

• It’s less potent on its own compared to glycolic acid, so results may be slower.

• Overuse can still cause mild dryness, irritation, or sensitivity.

• Like all AHAs, it increases sun sensitivity—daily SPF is essential.

How to Use Malic Acid in Your Routine

Malic acid is often found in cleansers, toners, and exfoliating masks rather than standalone serums. Here are some guidelines:

• Frequency: Start 1–2 times a week and increase gradually if your skin tolerates it well.

• Application: Use at night after cleansing, then follow with a hydrating moisturizer.

• Avoid mixing: Don’t use alongside other strong exfoliants or retinoids on the same day to reduce irritation.

• SPF is a must: Protect your skin every morning with sunscreen.
