The INKEY List Mandelic Acid Treatment 10% + 0.1% Retinol, Fragrance-Free Night Serum for Fading Dark Spots

The INKEY List Mandelic Acid Treatment is a lightweight, fragrance-free formula using 10% mandelic acid and 0.1% retinol to visibly reduce dark spots and improve post-acne discoloration while hydrating skin.

This targeted treatment blends mandelic acid, a gentle alpha hydroxy acid, with a low-dose retinol and glycerin to accelerate surface cell turnover and support moisture balance. It’s designed for anyone aiming to fade hyperpigmentation, melasma-like patches, or acne marks without heavy irritation. The texture sits comfortably under a night cream and works as a focused step in evening routines.

How does this product help fade dark spots and acne marks?

Mandelic acid encourages mild chemical exfoliation to loosen pigmented skin cells, while retinol assists the natural renewal cycle so new, less-pigmented cells become visible. Glycerin prevents dryness during the process, maintaining skin comfort as surface renewal happens.

• 10% mandelic acid for gentle, effective exfoliation
• 0.1% retinol to support cell turnover
• Glycerin for sustained hydration and skin barrier support

Is this safe for sensitive or acne-prone skin?

Mandelic acid has a larger molecular size than some AHAs, which slows penetration and lowers irritation risk, making it a common choice for sensitive or acne-prone complexions. The formula is fragrance-free and kept at moderate actives to balance effectiveness and tolerance, but patch testing is recommended.

• Large-molecule mandelic acid reduces sting compared with smaller AHAs
• Low-dose retinol to limit potential irritation
• Fragrance-free, cruelty-free, and marketed for all skin types

How do I add it to my skincare routine?

Use the treatment in the evening as the final step on clean skin, applying a thin layer to affected areas. Follow with moisturizer if needed; avoid combining with other strong exfoliants or retinoids until tolerance is established. Always use sunscreen during the day while using exfoliating actives.

• Apply at night after cleansing and serums, before heavier creams if needed
• Start with every-other-night applications to build tolerance
• Use broad-spectrum SPF daily to protect renewed skin

When will I see results for pigmentation?

Individual responses vary, but many users notice gradual lightening of spots over several weeks as cell turnover increases. Consistent nightly use and strict daytime sun protection are essential to maintain progress. If irritation occurs, reduce frequency or consult a skincare professional.

• Visible changes typically unfold over weeks to months
• Daily SPF helps preserve and extend improvement
• Adjust frequency if skin becomes red or sensitized

Who is this for: This treatment suits people looking to reduce post-acne marks, age spots, or uneven tone who want a gentler AHA option than glycolic acid. It’s formulated for all skin types, including those with sensitivity concerns, provided users introduce the product gradually and protect their skin from UV exposure. Ideal for anyone seeking a compact, fragrance-free nightly treatment to target hyperpigmentation while keeping skin hydrated.
