INFORMATIONS PRODUIT

Duo Sérum Haute-Tolérance combines the regenerating action of retinol with the antioxidant protection of vitamin C to offer the skin dual efficacy, targeting the signs of aging and the radiance of the complexion.

Vitamin C Serum, with 10% stabilized vitamin C, protects the skin from external aggression and oxidative stress, while regulating melanin production to even out skin tone and reduce dark spots. It awakens the skin's radiance while reinforcing defense mechanisms against free radicals, for lasting protection.

Retinol Serum, thanks to its gentle formula containing 0.3% of a skin-friendly Pro-Retinol (or retinol ester, known as Retinyl Palmitate) and a natural Retinol Booster, acts on the signs of aging by reducing wrinkles, fine lines and pigmentation spots, while firming and smoothing skin texture. This serum is specially formulated to prolong the action of retinol while minimizing the risk of irritation, even on the most sensitive skin.

These two serums should be used together to smooth, protect and illuminate the skin, while providing targeted action against visible signs of aging and uneven skin tone.

VITAMIN C SERUM 10%: A light serum texture, easy to pick up and apply, that penetrates skin instantly without leaving a sticky or greasy film.

RETINOL SERUM 0.3%: A light, fresh, moisturizing, non-sticky emulsion texture. Quickly absorbed. Lightly mentholated for precise, reassuring application.

FAQ

Like all products in the PERS range, our Vitamin C Serum 10% has been designed and tested for all skin types and complexions. Universal, it is suitable for normal, oily or combination skin, as well as dry skin. Finally, it presents no risk to sensitive skin.

Vitamin C Serum 10% is applied in the morning to clean skin, to PROTECT the skin from the aggressions it will suffer throughout the day: pollution, environment, free radicals....

For complete protection, we recommend following with sun protection factor 50 sun protection every day, even on overcast days. UVA rays, which are primarily responsible for premature aging, generate oxidative stress all year round, even in winter. Vitamin C acts as an antioxidant shield.

A full pipette of Vitamin C Serum 10% is required for the face, neck and décolleté. Visit here our PERS application videos.

Recommended by dermatologists and widely used in cosmetics, retinol is one of the most effective active ingredients for accelerating cell renewal. Retinol is recognized for its ability to boost collagen and elastin production for smoother, more elastic and firmer skin. It also removes dead cells from the skin's surface, stimulating cell renewal. Pores are unclogged and skin texture refined, preventing the appearance of blackheads and/or blackheads.

We recommend applying PERS Concentrated Retinol Serum 0.3% every other evening, alternating with PERS Intense Repair Rich Cream. PERS Intense Repair Rich Cream to REPAIR.

As retinol is photosensitizing, we strongly recommend applying it only in the evening, to avoid skin irritation. In addition, we recommend that you protect your skin the next day with the PERS SPF50+ Daily Protection Gel or high SPF: 50+ (well, like every other day, isn't it?).

Three pea-sized doses of Retinol Serum 0.3% are required for the face, neck and décolleté. Visit here our PERS application videos.

It's perfectly possible to combine Vitamin C and Retinol. However, we recommend using them at two different times of the day. Retinol must be applied in the evening, as the photosensitizing molecule can cause irritation during the day. Vitamin C is suitable for application in the morning, to PROTECT the skin against the aggressions it will be subjected to throughout the day.
