ISDIN Flavo-C Vitamin C Day Serum Ampoules — 10 Single‑Dose Vials, Hyaluronic Acid & UltraGlycans for Radiance

ISDIN Isdinceutics Flavo-C Ultraglican is a concentrated daytime serum in single-dose ampoules that blends vitamin C, UltraGlycans and hyaluronic acid to brighten skin, reduce the look of fine lines and deliver an immediate healthy glow.

This ampoule-format serum is designed for targeted antioxidant care and visible radiance. Each glass vial contains a measured dose of stable vitamin C in its natural form, combined with UltraGlycans (a multi-weight glycosaminoglycan complex) and hydrating hyaluronic acid to support skin texture and surface hydration. Packaged as ten single-use doses, the formula minimizes oxidation and contamination while making application effortless for a morning skincare routine.

How quickly will I notice brighter, more radiant skin?

Many users observe an immediate "flash" effect after application — skin appears more luminous and even. Over repeated use, the vitamin C and antioxidant blend can help support long-term brightness and improved skin tone when used consistently alongside sun protection.

• Instant radiance: visible glow after first application
• Ongoing benefit: sustained brightness with regular morning use
• Packaging: single-dose ampoules preserve potency of vitamin C

Can this serum help soften fine lines and improve skin texture?

The combination of hyaluronic acid and UltraGlycans works to hydrate and plump surface tissue, which can reduce the appearance of fine lines. While individual results vary, the formula supports skin elasticity and smoother texture as part of a consistent regimen.

• Hyaluronic acid: immediate hydration and plumping
• UltraGlycans: multi-weight glycosaminoglycans to support firmness
• Daily use: best results seen with continued morning application

Is this safe to use in the morning, and can I apply sunscreen afterwards?

Yes — the product is intended for daytime antioxidant protection and pairs well with sunscreen. Apply the ampoule content to clean skin, allow it to absorb, and follow with a broad-spectrum sunscreen to protect against UV-induced oxidative stress.

• Daytime use: formulated for morning routines
• Sunscreen compatible: layer a high-SPF protection after absorption
• Non-contaminating dosing: single-use ampoules reduce oxidation risks

How do I use the ampoules safely and get the most from each dose?

Break each glass ampoule at the neck following the included instructions, dispense the serum onto fingertips, and smooth over face and neck. Use once per day in the morning; a single ampoule contains a full dose for one application to ensure potency and hygiene.

• One ampoule per morning for a measured dose
• Apply to clean, dry skin and allow to absorb before moisturizer
• Store in a cool, dry place away from direct sunlight

Who this is for: ISDIN Isdinceutics Flavo-C Ultraglican is suitable for people seeking daytime antioxidant protection, brighter-looking skin and additional surface hydration. It's a fit for anyone with early signs of aging, dullness, or dehydration who prefers single-dose packaging for potency and convenience. Avoid use if you have a known sensitivity to any listed ingredients and consult a dermatologist for concerns about reactive or very sensitive skin.
