ISDIN Flavo‑C Vitamin C Brightening Antioxidant Serum — 1.0 fl oz, Fragrance‑Free, Lightweight

ISDIN Flavo‑C is a concentrated vitamin C serum formulated to brighten skin, support elasticity, and help protect against free‑radical damage from UV exposure.

This antioxidant facial serum pairs stabilized ascorbic acid with ginkgo biloba to target uneven tone, loss of firmness, and dehydration. Developed in Spain and free of fragrance and sulfates, the lightweight formula absorbs quickly and can be used morning and/or evening as part of a regular skincare routine.

How does this serum improve dull or uneven skin tone?

The concentrated vitamin C (ascorbic acid) in Flavo‑C works to support skin functions that promote a more unified, luminous appearance. Regular application helps the complexion look brighter while supporting overall radiance without harsh exfoliation.

• Stabilized ascorbic acid delivers antioxidant support to the skin surface.
• Lightweight formulation absorbs quickly into the complexion.
• Fragrance‑free formula minimizes irritation for sensitive users.

Can this serum help with firmness and fine lines?

The formulation is designed to support skin elasticity and the appearance of fine lines by combining vitamin C’s supporting effects with antioxidants from ginkgo biloba. While not a clinical cure, routine use aims to improve the look and feel of firmness over time.

• Antioxidant blend supports skin resilience and texture.
• Daily application complements other anti‑aging steps in your routine.
• Suitable to pair under moisturizers and sunscreens for daytime use.

How should I use ISDIN Flavo‑C in my skincare routine?

Apply a few drops to clean, dry skin after cleansing and before moisturizer. Use in the morning to boost antioxidant protection and again at night if desired; always follow with sunscreen during daytime to protect against UV damage.

• Use 2–3 drops for face and neck, morning and/or evening.
• Layer under moisturizer and daily SPF for daytime protection.
• Store in a cool, dark place to preserve potency.

Who is this for? ISDIN Flavo‑C Brightening and Antioxidant Vitamin C Serum is intended for anyone seeking to address dullness, early signs of aging like fine lines and reduced firmness, dehydrated skin, or skin impacted by sun exposure. It suits users wanting a fragrance‑free, sulfate‑free antioxidant boost developed with Spanish formulation standards and integrates easily into both beginner and advanced skincare routines.
