Naturium Multi-Bright Advanced Serum — 30 mL exfoliating AHA serum with lactic & glycolic acid for brighter, smoother skin

Naturium Multi-Bright Advanced Serum is an exfoliating, antioxidant-rich serum that blends lactic and glycolic acids with L-arginine to brighten skin, refine texture, and help reduce the appearance of dark spots.

This lightweight, water-based serum combines two AHAs—lactic acid and glycolic acid—with L-arginine, botanical fruit extracts, allantoin, and bisabolol to provide gentle resurfacing while helping to soothe and support the skin barrier. With a formula pH of 3.5–4.0, the serum is designed for effective acid activity without unnecessary harshness when used as directed. Naturium’s approach balances clinically minded actives and comforting botanicals so you can add an effective brightening step to your routine responsibly.

How will this serum change my skin’s brightness and texture?

The combined lactic and glycolic acids work to encourage the skin’s natural renewal, helping to smooth roughness and reveal fresher, more luminous skin over time. Regular, controlled exfoliation can diminish the look of uneven tone and surface discoloration when used alongside sun protection.

• Dual-AHA action: lactic for gentler moisture-retaining exfoliation, glycolic for surface renewal
• Improves visible texture and refines skin surface
• Targets the appearance of dark spots with gradual renewal

Is this serum suitable for sensitive or reactive skin?

The formula includes soothing components like allantoin and bisabolol plus L-arginine to help reduce irritation risks commonly associated with acids. Still, because the active pH is between 3.5 and 4.0, a patch test is recommended before full-face use, and start with lower frequency if you have sensitivity.

• Contains calming agents to support comfort during exfoliation
• Patch test advised; introduce slowly (every other day) if sensitive
• Avoid mixing with other strong actives initially to minimize irritation

How should I add this serum into my AM/PM routine?

Apply 1–2 pea-sized drops to clean, dry skin on your face, neck, or chest. It can be used in the morning or evening, but when used during the day pair it with a broad-spectrum sunscreen to protect freshly exfoliated skin from UV exposure.

• Use after cleansing and before moisturizers or oils
• Start with one application every other night, then increase as tolerated
• Always follow with SPF during daytime use

What supporting ingredients help protect and comfort the skin?

Beyond exfoliating acids, this serum includes an antioxidant-rich superfood complex and naturally derived fruit extracts to help defend against environmental stressors. Allantoin and bisabolol help moisturize and soothe, while L-arginine supports skin resilience during renewal.

• Superfood and fruit extracts for antioxidant support
• Allantoin and bisabolol to calm and hydrate the skin barrier
• L-arginine to aid skin comfort and functional recovery

Who this is for: Naturium Multi-Bright Advanced Serum is aimed at anyone seeking a measurable, science-forward brightening step—ideal for people concerned with dullness, uneven texture, or the appearance of dark spots who are willing to introduce an AHA product thoughtfully. If you have very reactive skin, are pregnant, or are using certain prescription treatments, consult a professional and perform a patch test before integrating this serum into your routine.
