• Slows signs of aging with gentle resurfacing
• Ideal for acne-prone, dull, and textured skin

Mandelic Acid is an alpha hydroxy acid (AHA) derived from bitter almonds. Unlike glycolic or lactic acid, it has a larger molecular size, making it gentler and slower penetrating — ideal for sensitive, dark-toned, or acne-prone skin. Mandelic Acid offers dual-action benefits: exfoliates the surface while penetrating deeper into pores to fight bacteria and regulate sebum. It promotes brighter, smoother, and clearer skin, and is suitable for leave-on serums, peels, and exfoliating toners.

1. Gentle Exfoliating Night Serum

Use 5% Mandelic Acid in a glycerin + propanediol base with panthenol and licorice extract for tone correction and acne clearing.

2. Clarifying Toner

Blend Mandelic Acid with cucumber extract and betaine in a hydrating base. Use at 3% for daily exfoliation and glow.

3. Post-Acne Spot Treatment

Formulate a 10% Mandelic Acid gel with alpha arbutin and azelaic acid for fading spots and smoothing rough texture.

4. Peel Mask for Oily Skin

Create a rinse-off clay-based mask with Mandelic Acid and tea tree oil to reduce congestion and exfoliate dead skin.

5. Anti-Aging Cream with AHA

Add 3% Mandelic Acid into a night cream with peptides and squalane for fine line smoothing over time.

Q1: Is Mandelic Acid safe for daily use?

A1: Yes, at low concentrations (2–5%), it’s safe for daily or alternate day use. For peels (10%), use once a week.

Q2: Does Mandelic Acid cause purging?

A2: It may cause mild purging as skin cells turn over faster, especially if pores are clogged. This usually resolves within 2–3 weeks.

Q3: Can I use Mandelic Acid during the day?

A3: Yes, but always wear sunscreen as AHAs increase sun sensitivity.

Q4: Is it safe for darker skin tones?

A4: Absolutely. It’s one of the best acids for melanin-rich skin with less risk of post-inflammatory hyperpigmentation.

Q5: Can I combine it with Niacinamide or Retinol?

A5: Yes. For sensitive skin, alternate days are recommended. Avoid layering with strong retinoids initially.
