Naturium Mandelic Acid 12% Exfoliating Serum — 1 oz with Niacinamide for Gentle Anti-Aging & Texture Refinement

Naturium Mandelic Topical Acid 12% is a leave-on AHA treatment formulated to gently exfoliate, refine texture, and help improve the appearance of fine lines and uneven tone.

This concentrated serum blends mandelic acid with niacinamide and natural fruit acids to offer slow-penetrating exfoliation with reduced irritation risk. Designed as a leave-on step in your nighttime routine, it supports visible skin-smoothing and can be introduced gradually to suit sensitive, combination, acne-prone, dry, or aging skin. The formula is pH-appropriate and free from parabens, gluten, and animal testing, and most variants are synthetic fragrance free.

How does this product exfoliate without harsh irritation?

Mandelic acid is an alpha hydroxy acid (AHA) with a larger molecular structure, so it penetrates the skin more slowly than smaller AHAs. This slower action reduces the probability of stinging and redness while still promoting surface cell turnover and smoother texture.

• 12% mandelic acid concentration for effective but controlled exfoliation
• Combined with natural fruit acids to support gentle resurfacing
• Formulated at an appropriate pH to balance efficacy and skin compatibility

Will the niacinamide in the formula help with tone and pores?

Yes — niacinamide is included to help even skin tone, calm inflammation, and support the appearance of refined pores. It works well alongside mandelic acid to address discoloration and texture without amplifying irritation when introduced properly.

• Niacinamide complements exfoliation by targeting uneven tone and brightness
• Useful for minimizing the look of enlarged pores and balancing sebum
• Appropriate for layering with hydrating moisturizers and SPF the following day

How should I add this treatment to my routine safely?

Start with a patch test and use 1–2 times per week, gradually increasing frequency as tolerated. Apply on clean, dry skin at night, follow with a moisturizer, and always use sunscreen during the day — exfoliants can increase sun sensitivity.

• Apply to face after cleansing, before moisturizer, avoid eye area
• Introduce slowly: every few nights, then increase based on tolerance
• Use daily SPF in the morning to protect renewed skin cells

Are there skin types or conditions that should avoid this product?

While formulated for broad compatibility, those using retinoids, other chemical exfoliants, or with severely compromised barrier function should consult a dermatologist first. Discontinue use if persistent irritation, swelling, or severe discomfort occurs.

• Avoid mixing with strong retinoid regimens without professional guidance
• Not recommended on broken, inflamed, or sunburned skin
• Patch test recommended for very sensitive or reactive skin

Who this is for: This bottle is intended for people seeking an effective, leave-on chemical exfoliant that balances potency with gentleness. It suits anyone wanting to address texture, early signs of aging, uneven tone, or blemish-prone skin while minimizing irritation: especially useful for sensitive-to-moderate skin types who prefer AHAs but need a milder profile. Pair it with hydrating and sun-protective steps for best results.
