ISDIN Flavo-C Ultraglican Vitamin C Serum 10 Ampoules — Hyaluronic Acid Brightening Antioxidant

ISDIN Flavo-C Ultraglican is a daytime antioxidant serum in single-dose ampoules that combines vitamin C, UltraGlycans and hyaluronic acid to brighten skin and help smooth the look of fine lines.

Formulated in Spain, this daily facial serum delivers a concentrated antioxidant boost in ten 0.06 fl oz ampoules designed for short treatment cycles or travel. The formula pairs the stable, naturally occurring form of vitamin C with hydration-focused ingredients to refresh dull skin, reinforce elasticity, and provide an immediate radiance effect. Packaged as single-use ampoules, it avoids preservatives and helps maintain ingredient potency from the first to the last application.

How does this serum improve skin radiance and tone?

The vitamin C used in Flavo-C Ultraglican supports the skin’s antioxidant defenses and helps even skin tone for a brighter appearance. Regular topical use can reduce the look of fatigued, lackluster skin while supporting a more luminous complexion.

• Stabilized natural vitamin C works against oxidative stress that dulls skin
• UltraGlycans help preserve hydration and bolster the skin’s texture
• Lightweight ampoule format delivers a fresh dose for each application

Will it help reduce fine lines and dryness?

This serum combines hyaluronic acid and UltraGlycans to restore moisture and plump the surface, which can soften the visible appearance of fine lines. While not a replacement for clinical procedures, improved hydration and antioxidant support contribute to a smoother-looking texture over time.

• Hyaluronic acid attracts and locks in moisture for temporary plumping
• UltraGlycans support elasticity and comfort in dry or mature skin
• Daily application helps maintain a hydrated, supple appearance

Is this product suitable for daytime use and sun protection routines?

Flavo-C Ultraglican is intended for daytime application as an antioxidant step that complements sun protection. Product materials note an action of sun protection (SPF 50) associated with the daytime routine; however, always follow with a dedicated broad-spectrum sunscreen as recommended for reliable UV defense.

• Use as the antioxidant/serum step before moisturizer and sunscreen
• Follow with a separate SPF product for full, proven sun protection
• Single-dose ampoules keep the vitamin C stable until use

How do I incorporate the ampoules into my skincare routine?

Apply one ampoule to clean, dry skin in the morning: twist or snap the top, dispense the serum, and smooth over face and neck. Allow it to absorb, then layer your moisturizer and sunscreen; the texture is lightweight and works well under makeup.

• Use one 0.06 fl oz ampoule each morning for a 10-day treatment cycle
• Apply to cleansed skin; follow with moisturizer, then SPF
• Suitable for travel or as a boost before events for a flash glow

Who is this for: ISDIN Flavo-C Ultraglican is geared toward anyone seeking a compact, potent daytime serum to improve radiance, hydrate dry or aging skin, and support the appearance of smoother texture. It is useful for people wanting a short-course, preservative-minimized vitamin C routine delivered in disposable ampoules—especially those who travel or who want a targeted brightening boost while maintaining a separate, dedicated sunscreen step.
