ISDIN Isdinceutics Flavo-C Intense
Daily exposure to UV radiation, pollution and oxidative stress accelerates skin ageing, contributing to dullness, wrinkles, uneven skin tone and loss of firmness. ISDIN Isdinceutics Flavo-C Intense is an advanced biphasic anti-ageing serum formulated with 15% vitamin C to help combat these visible signs of ageing while restoring radiance and improving overall skin quality.
Powered by ISDIN’s innovative Tri-Antiox Complex, this daily treatment combines three complementary forms of vitamin C with three antioxidant boosters to optimise stability, skin penetration and antioxidant performance. The result is a comprehensive formula that helps brighten the complexion, visibly reduce wrinkles, improve firmness and protect the skin against free radical damage.
Suitable for all skin types, including sensitive skin, this lightweight serum is designed for morning use and integrates easily into any anti-ageing skincare routine.
What is ISDIN Isdinceutics Flavo-C Intense?
ISDIN Isdinceutics Flavo-C Intense is a biphasic facial serum developed to deliver a high concentration of vitamin C while overcoming some of the main challenges associated with this powerful antioxidant: oxidation, stability and skin penetration.
Its innovative two-phase technology keeps the aqueous and oil phases separate until the moment of application, helping preserve the stability of the active ingredients. Once mixed, the serum delivers multiple forms of vitamin C throughout different layers of the epidermis, providing broad antioxidant protection while helping to improve the visible signs of skin ageing.
With continued daily use, the complexion appears brighter, smoother, firmer and more even.
Who is this serum recommended for?
This serum is suitable for adults looking to address early or established signs of skin ageing. It is particularly recommended for those experiencing:
- Fine lines and wrinkles
- Dull or tired-looking skin
- Uneven skin tone
- Loss of firmness and elasticity
- Reduced skin radiance
- Daily exposure to environmental stressors such as UV radiation and pollution
Its formula has been tested on all skin types, including sensitive skin, and is suitable for daily morning use.
Benefits of ISDIN Isdinceutics Flavo-C Intense
With regular use, this antioxidant serum helps to:
- Visibly reduce the appearance of wrinkles

According to ISDIN clinical evaluations performed over 112 days of daily use, participants experienced measurable improvements in luminosity, wrinkle appearance, skin uniformity and firmness. In addition, an artificial intelligence-based skin age assessment estimated that skin appeared up to three years younger after four months of consistent use.
Tri-Antiox Complex: Multi-Level Vitamin C Technology
The innovative Tri-Antiox Complex lies at the heart of the formula, combining three complementary forms of vitamin C with three antioxidant boosters to maximise efficacy.
Each form of vitamin C offers distinct properties and skin affinity, allowing progressive delivery across different layers of the epidermis while helping maintain antioxidant activity throughout the day.
This multi-level approach supports brighter, healthier-looking skin while helping defend against oxidative damage that contributes to premature ageing.
Key Ingredients and Their Functions
Three Forms of Vitamin C
The formula combines three carefully selected vitamin C derivatives that work synergistically:
- L-Ascorbic Acid is the pure form of vitamin C, providing powerful antioxidant protection while helping brighten the complexion and support collagen production.
- 3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that helps improve skin tone, reduce the appearance of pores and provide long-lasting antioxidant activity.
- Ascorbyl Tetraisopalmitate is an oil-soluble vitamin C derivative that penetrates efficiently into the skin, contributing to improved luminosity, hydration and smoother skin texture.
Together, these forms of vitamin C provide comprehensive antioxidant protection while targeting multiple visible signs of ageing.
Antioxidant Boosters
To further optimise vitamin C performance, the serum includes three complementary antioxidants:
- Hinokitiol, which helps neutralise free radicals while supporting the recycling of vitamin C.
- Levulinic Acid, which enhances the distribution of active ingredients throughout the epidermis.
- Tocopherol (Vitamin E), a well-known antioxidant that works synergistically with vitamin C to strengthen the skin’s defence against oxidative stress.
This combination helps maximise antioxidant efficacy while improving the overall stability of the formula.
Biphasic Technology for Enhanced Stability
Vitamin C is naturally prone to oxidation, which can reduce its effectiveness over time. To address this challenge, ISDIN has developed a biphasic delivery system that separates the water-based and oil-based phases until application.
Immediately before use, the two phases are mixed together, helping preserve the freshness of the active ingredients while creating a lightweight texture that spreads comfortably across the skin.
This technology contributes to optimal product performance throughout its period of use.
How to Use ISDIN Isdinceutics Flavo-C Intense?
For optimal results:
- Cleanse and dry the skin thoroughly.
- Dispense two pumps into the palm of your hand.
- Mix both phases until the serum becomes homogeneous.
- Apply a thin layer evenly over the face.
- Gently massage until fully absorbed.
- Use every morning.
- Follow with a broad-spectrum sunscreen as the final step of your daytime skincare routine.
Consistent daily use helps maximise the antioxidant and anti-ageing benefits of the formula.
Complete Your Antioxidant Skincare Routine
To enhance your daily skincare routine, pair this serum with complementary ISDIN products.
After applying the serum, follow with a moisturiser suited to your skin type to reinforce hydration and support the skin barrier. During the day, always finish with a high-protection sunscreen such as an ISDIN facial SPF to help defend against UV-induced premature ageing and preserve the antioxidant benefits of vitamin C.
For those looking to build a comprehensive anti-ageing routine, incorporating complementary antioxidant and collagen-supporting skincare products can further improve skin brightness, firmness and overall appearance.
