Sometimes all it takes is a mirror that’s a little too clear in the morning to see it: the complexion seems less luminous, the features more tired and some wrinkles begin to appear. Not necessarily enough to disrupt your entire beauty routine, but enough to look for a treatment capable of playing on several fronts.
It is precisely this niche that a concentrated formula intends to occupy. Its approach is not limited to wrinkles and focuses on several visible changes in the skin, with an active ingredient that has become essential in facial routines.
ISDIN Flavo-C Intense focuses on 15% vitamin C
At the heart of the serum is TRI-ANTIOX COMPLEX. This brings together three vitamins C and three boosters. According to information provided by ISDIN, these promote the release of vitamin C and multiply its antioxidant power. The formula has also been designed to ensure its penetration and diffusion through different layers of the epidermis.
The packaging also plays a role: it aims to maximize the stability and effectiveness of vitamin C. A detail which becomes important when we know that the product displays a concentration of 15%.
This ISDIN serum targets 9 signs of skin aging
Flavo-C Intense is not limited to brightness. ISDIN claims action on nine signs: wrinkles, luminosity, uniformity, firmness, elasticity, hydration, redness, signs of fatigue and skin density.
The brand is based on a clinical evaluation carried out on 35 subjects aged 40 to 70, all skin types, including sensitive, for 112 days under normal conditions of use. This data is internal to ISDIN and dates from 2025.
Another clinical study mentioned by the brand involves 35 women after daily application of Flavo-C Intense for four months. The evaluation was carried out with an objective algorithm for analyzing skin aging.
At 60 euros for 50 ml, the serum is in a range where you can legitimately expect more than a simple healthy glow effect. Its interest lies precisely in this multi-target approach, designed to bring together several concerns in the same bottle.
How to apply ISDIN Flavo-C Intense serum?
The two-phase formula requires a particular gesture. Every day, place two pumps in the palm of your hand, then mix the two phases until you obtain a uniform color.
Then apply a thin layer to your clean, dry face, then apply light pressure until completely absorbed. There is therefore no need to multiply the doses: two pumps correspond to the protocol indicated by ISDIN.
Last gesture not to be skipped in your routine: sun protection. ISDIN recommends ending with its application. Between its concentration of 15% vitamin C, its TRI-ANTIOX COMPLEX and its nine skin targets, Flavo-C Intense clearly displays its ambitions behind its price of 60 euros.
