Mandelic Acid

Mandelic Acid

Gentle exfoliating AHA for improving skin texture, clarity, and uneven tone while supporting a more balanced, refined complexion.

INCI: Mandelic Acid.

Appearance: White crystalline powder

Solubility: Water-soluble.

Typical Use Level: 2–10%.

Mandelic Acid is an alpha hydroxy acid (AHA) known for its larger molecular size, which allows for slower penetration and a more controlled exfoliation process. It helps improve the appearance of uneven skin tone, dullness, and texture while being suitable for formulations designed for sensitive or blemish-prone skin.

What It Does

Mandelic Acid is a surface-exfoliating AHA that helps improve skin clarity, smoothness, and overall tone.

Due to its slower penetration profile, it provides a more controlled exfoliation compared to smaller-molecule AHAs, making it a strong choice for formulations targeting sensitive, acne-prone, or reactive skin types.

Key Benefits

• Helps remove dead skin cells for smoother texture.
• Improves the appearance of uneven skin tone and dullness.
• Supports clearer-looking skin in blemish-prone formulations.
• Provides controlled exfoliation with reduced irritation potential.
• Suitable for sensitive and combination skin systems.

Suggested Use Levels

• 2–5% in daily-use exfoliating toners and serums.
• 5–8% in clarifying and resurfacing treatments.
• 8–10% in stronger exfoliation systems.

Ideal Applications

• Exfoliating toners and serums
• Acne and clarifying formulations
• Brightening and tone-correcting products
• Sensitive skin exfoliation systems
• Texture-refining treatments

Formulation Notes

• Dissolve in the water phase with proper mixing.
• Effective in formulations with a pH range of approximately 3.5–4.5.
• Final pH adjustment is critical for performance.
• Works well alongside niacinamide (in balanced systems), soothing agents, and hydration actives.

As with all exfoliating acids, final formulation, pH, and skin compatibility should be properly evaluated. Guessing is not a formulation strategy.
