ISDIN Flavo-C Brightening Vitamin C Face Serum, 1 fl oz — Antioxidant Protection & Radiance

ISDIN Isdinceutics Flavo-C is a potent vitamin C face serum formulated to brighten skin, protect against free radicals, and help restore elasticity.

Designed and developed in Spain, this lightweight serum combines stabilized ascorbic acid (vitamin C) with ginkgo biloba and complementary antioxidants to target uneven tone, sun-related damage, and early signs of aging. Fragrance-free and sulfate-free, the formula is made for daily use under sunscreen or moisturizer to enhance radiance and support skin’s natural resilience without added irritants.

How does this serum protect skin from environmental damage?

The formula uses ascorbic acid — a well-known antioxidant — alongside ginkgo biloba to neutralize free radicals created by UVA and UVB exposure. By reducing oxidative stress, it helps preserve skin texture and the appearance of firmness when used consistently.

• High-concentration vitamin C (ascorbic acid) for antioxidant support
• Ginkgo biloba provides complementary antioxidant activity
• Daily application helps defend against pollution and sun-induced free radicals

Will this serum improve brightness and uneven tone?

Regular use aims to enhance overall luminance and even out skin tone thanks to vitamin C’s role in supporting skin functions related to pigment and radiance. Many users notice a more uniform complexion and a reduction in the dull, tired appearance caused by environmental stress.

• Targets dullness to reveal a refreshed, brighter look
• Supports more even skin tone over time with consistent use
• Lightweight texture layers easily under moisturizers and sunscreens

How should I fit this serum into my skincare routine?

Apply a few drops of the serum to clean, dry skin once or twice daily—morning use is recommended when pairing with SPF to maximize antioxidant protection. Follow with a moisturizer and broad-spectrum sunscreen during the day; at night use your regular hydrating products.

• Use on cleansed skin before heavier creams or oils
• Combine with daily broad-spectrum SPF for daytime protection
• Fragrance-free and sulfate-free for compatibility with most regimens

What skin concerns does this formula specifically address?

This serum is designed for multiple common concerns: fine lines, loss of firmness, dehydration, and sun-related discoloration. The antioxidant blend supports skin’s appearance and texture rather than making clinical claims; results are best with ongoing use and effective sun protection.

• Helps reduce the visible signs of fine lines and early aging
• Supports elasticity and a firmer-looking complexion
• Hydrating ingredients help alleviate surface dryness
• Focused on addressing sun damage and uneven tone
