Mandelic acid is increasingly popular for those looking for effective exfoliation without irritation. Derived from bitter almonds, this larger molecule penetrates the skin more slowly compared to other AHAs, making it ideal for sensitive skin. It helps improve skin tone, reduce hyperpigmentation, and refine texture while maintaining skin barrier integrity, making it an excellent choice for those new to chemical exfoliation.

What is Mandelic Acid?

Mandelic acid is an alpha-hydroxy acid (AHA) derived from bitter almonds. Its larger molecular size, compared to glycolic acid, means it penetrates the skin more gradually, reducing the risk of irritation. This slow absorption makes mandelic acid particularly suitable for sensitive skin while still delivering effective exfoliation and brightening benefits. It also has antibacterial properties, making it beneficial for both acne-prone and aging skin.

Benefits of Mandelic Acid for Skin:

• Gentle exfoliation: Removes dead skin cells to promote smoother, brighter skin with minimal irritation.

• Reduces hyperpigmentation: Helps fade dark spots, post-inflammatory hyperpigmentation, and melasma.

• Improves acne and congestion: Its antibacterial properties make it effective in targeting breakouts and clogged pores.

• Evens skin tone: Refines texture and promotes a more uniform complexion.

• Anti-aging: Encourages collagen production, reducing the appearance of fine lines and wrinkles.

• Safe for sensitive skin: Its slow penetration makes it less likely to cause redness or discomfort.

What Type of Skincare Products Is Mandelic Acid Typically Used In?

Mandelic acid is commonly formulated into:

• Serums: Lightweight, water-based products for targeted treatment of uneven skin tone and acne.

• Exfoliating toners: Mild solutions that can be used daily or several times a week.

• Cleansers: Rinse-off options that are ideal for beginners or sensitive skin.

• Peels and Masks: Higher concentrations used periodically for deeper exfoliation and brightening.

You’ll want to look for products like Prequel's Multi-Acid Milk AHA Peel that focus on exfoliation—while formulating with ingredients like squalane to maintain hydration.

Concentration Levels for Mandelic Acid:

• Low concentration (5-10%): Ideal for beginners or those with sensitive skin, offering gentle exfoliation and brightening.

• Moderate concentration (10-20%): Provides more noticeable results for uneven tone, mild acne, and texture concerns.

• High concentration (20-30%): Found in professional treatments or peels to target hyperpigmentation and deeper exfoliation.

Its larger molecular size reduces irritation, even at higher concentrations, making it more tolerable for a broader range of skin types.

Is It Okay to Use Mandelic Acid Daily?

Yes, mandelic acid is one of the few AHAs suitable for daily use, especially in lower concentrations (5-10%). Because it absorbs slowly, it’s less irritating than smaller AHAs like glycolic acid.

For those new to mandelic acid or with highly sensitive skin, start by using it 2-3 times a week and gradually increase frequency as your skin builds tolerance. Always wear sunscreen during the day, as AHAs can increase photosensitivity.

Who Should Use Mandelic Acid?

Mandelic acid is suitable for:

• Individuals with sensitive skin seeking gentle exfoliation.

• Those with hyperpigmentation or melasma looking to brighten their skin tone.

• People with acne-prone skin, as it helps reduce breakouts while being less irritating than other AHAs.

• Individuals addressing fine lines and uneven texture who need a mild anti-aging solution.

Mandelic acid is a great choice for those who find stronger acids, like glycolic or salicylic acid, too harsh.

What Skincare Ingredients Pair Well with Mandelic Acid?

Mandelic acid works well with:

Niacinamide

Soothes the skin, enhances hydration, and reduces inflammation, complementing mandelic acid’s brightening effects. Both are well tolerated by most skin types and can be used together safely to promote more even looking skin.

Hyaluronic Acid

Balances hydration, preventing dryness after exfoliation from other actives.

Ceramides

Strengthens the skin barrier while mandelic acid gently exfoliates reducing risk of irritation.

Azelaic Acid

Targets hyperpigmentation and acne without overwhelming the skin and when combined with mandelic acid can lead to improved skin tone and texture.

For best results, layer mandelic acid first, allow it to absorb, and then apply complementary ingredients.

Are There Any Ingredients that Should Not Be Used with Mandelic Acid?

Avoid combining mandelic acid with:

Other AHAs or BHAs

Using multiple exfoliants can lead to over-exfoliation, dryness, and irritation. Alternate use instead.

Retinoids

Using retinoids with mandelic acid can increase sensitivity and lead to peeling. Use retinoids on alternating nights.

Vitamin C

Combining mandelic acid and Vitamin C can destabilize formulations and irritate the skin. Use mandelic acid at night and Vitamin C in the morning.

As with any active ingredient, it’s important to avoid overloading your skin to keep the barrier healthy.
