CLARINS Multi-Active Brightening Glow Serum — 1 fl oz, Vitamin C + AHA for Radiance & Texture Refinement

Clarins Multi-Active Brightening Glow Serum is a shake-to-activate dual-phase serum that combines stabilized oil-soluble Vitamin C with glycolic AHA to brighten skin, refine texture, and smooth the appearance of fine lines.

This lightweight, 1 fluid ounce serum is formulated to deliver immediate radiance and ongoing improvement in skin texture by pairing two complementary actives in separate phases. The oil layer contains a stabilized, oil-soluble form of Vitamin C that targets dullness and uneven tone, while the water layer contains glycolic acid (an AHA) to gently exfoliate and refine pores and surface texture. Shake before each use to blend the phases and ensure the actives are freshly combined for every application.

How should I use this serum in my daily routine?

Use the serum on clean, dry skin once or twice daily—morning and/or night—depending on your routine and tolerance. Shake the bottle to mix the oil and water phases, then smooth the formula over face and neck, avoiding direct contact with the eye contour. Follow with moisturizer and daily sunscreen in the morning.

• Shake to blend oil (Vitamin C) and water (AHA) layers before each application
• Apply with press-and-release motions, working downward over neck and décolleté
• Avoid the eye area; use sunscreen after morning application

What visible improvements can I expect and when?

The serum is designed to produce immediate radiance and to smooth skin texture with continued use. Users typically notice a fresher, more luminous appearance after initial applications, while refinement of pores and texture develops over weeks as exfoliation and brightening actions accumulate. Results vary by skin type and frequency of use.

• Instant glow from lightweight oil and light-reflecting formulation
• Gradual texture smoothing thanks to glycolic acid exfoliation
• Pore appearance can look more refined with regular application

Can all skin types use this formula safely?

The serum is formulated for all skin types but contains an AHA and a concentrated form of Vitamin C, so those with sensitive or reactive skin should introduce it gradually. Patch-test on a small area first and start with once-daily or alternate-night use until tolerance is verified. If irritation occurs, reduce frequency or stop and consult a skincare professional.

• Suitable for normal, combination, and oily skin with standard introduction
• Sensitive skin: patch test and build tolerance slowly
• Always use sunscreen after daytime AHA/Vitamin C use

Who is this for? Clarins Multi-Active Brightening Glow Serum is ideal for anyone wanting a targeted boost in radiance, more even skin tone, and smoother surface texture—particularly those noticing early signs of unevenness, dullness, or pore visibility. It fits into both simple and layered regimens and suits users looking for a modern, shake-to-activate delivery that keeps potent actives separate until use.
