CLARINS Multi-Active Brightening Glow Serum with Vitamin C + AHA, 1 fl oz — Shake-to-Activate, Radiance & Texture Refining

Clarins Multi-Active Brightening Glow Serum is a two-phase, shake-to-activate serum that combines stabilized oil-soluble Vitamin C with glycolic AHA to brighten, refine texture, and help even skin tone.

This lightweight serum pairs an oil-soluble form of stabilized Vitamin C with a water-soluble AHA (glycolic acid) in separate layers that are shaken together before use. The formulation is designed to deliver antioxidant support plus gentle exfoliation in a single daily or nightly step, targeting dullness, uneven tone and the look of texture while remaining suitable for all skin types.

How does the two-phase "shake-to-activate" formula work?

Clarins presents Vitamin C in an oil layer and glycolic acid in a water layer. Shaking the bottle blends the two phases so each pump dispenses a homogeneous serum with both brightening and resurfacing actions ready to apply.

• Oil layer: stabilized, oil-soluble Vitamin C to support radiance and target dullness.
• Water layer: glycolic acid (AHA) for gentle chemical exfoliation and texture refinement.
• Shake before each use to re-emulsify and ensure consistent dosing.

What visible improvements should I expect and when?

Results vary by skin and routine, but users commonly notice an immediate brightening effect and smoother-feeling skin with continued nightly or morning use. Pore appearance and uneven tone can improve over several weeks as exfoliation and antioxidant actions work together.

• Instant: a refreshed, more radiant surface appearance right after application.
• Short term (days to weeks): smoother texture and more even-looking tone.
• With continued use: reduced visibility of pores and a more luminous complexion.

How do I use this serum safely in my routine?

Apply after cleansing and before moisturizers or sunscreens. Use the serum in the morning or evening, avoiding eye contours, and press gently downward across face, neck and décolleté to spread the product evenly.

• Shake bottle to blend phases, then dispense one to two pumps.
• Avoid eye area; follow with SPF during daytime use.
• Introduce gradually if you have sensitive skin and monitor for irritation.

Can this serum be combined with other active ingredients?

It pairs well with many anti-aging and hydrating products, but take care when layering other strong exfoliants or prescription actives. If you use retinoids, potent acids, or professional exfoliants, space applications to reduce irritation.

• Compatible with hydrating serums and creams for added moisture.
• Use sunscreen daily to protect freshly exfoliated skin.
• Consult a dermatologist if combining with prescription treatments.

Who is this for: The Clarins Multi-Active Brightening Glow Serum suits anyone wanting a single-step product that targets dullness, uneven tone and surface texture. It's formulated for all skin types seeking antioxidant brightening plus gentle AHA exfoliation in a lightweight, daily-friendly serum; those with very sensitive or allergy-prone skin should patch-test or consult a professional before regular use.
