Proteomic Serum
Filling does not mean firmness.
Skin cells do not produce collagen but rather procollagen, an immature form of collagen that they release into the extracellular space. Once outside the cell, enzymes convert procollagen into mature collagen.
The difference between the two is fundamental.
While pro-collagen cannot integrate into the dermal structure and only provides a temporary plumping effect, mature collagen can integrate into the extracellular matrix and contribute to skin firmness.
It is the improved structural firmness that gives the sensation of "skin that fits better. "
Proteomic Serum acts on a crucial step in transforming plumpness into firmness: it facilitates the conversion of procollagen into mature, structurally functional collagen.
30 ml. Suitable for all skin types, including sensitive skin.
Ingredients
A minimalist, fragrance-free formula designed to preserve as much vitamin C as possible.
- 3-O-Ethyl Ascorbic Acid: 10%. A stable, fast-acting form of vitamin C for immediate results.
- Ascorbyl Glucoside: 5%. A stable form of vitamin C with gradual release for better skin compatibility.
- Tranexamic Acid: 2%. An active ingredient that helps reduce dark spots and blemishes.
- Pentylene glycol + propanediol: 5%. Moisturizers that soften the skin's stratum corneum to promote the absorption of active ingredients.
INCI: Water, 3-O-Ethyl Ascorbic Acid, Ascorbyl Glucoside, Pentylene Glycol, Tranexamic Acid, 1,3-Propanediol, Glycereth-26, Phenoxyethanol, Hydroxyethylcellulose, Ethylhexylglycerin, Sodium Phytate
When and how to apply it
Apply the VC15 Serum to clean, dry skin, preferably as part of your daytime routine. Wait a few minutes for the serum to absorb, and then apply your moisturizer.
One of the serum's main functions is to neutralize the free radicals that UV light generates in your skin, which oxidize the cell membrane and cause photoaging. That's why it's recommended to use it during the day.
That's why it also works perfectly in combination with the SPF 50 cream.
If you don't use sunscreen, you can easily apply any of the treatment creams after the serum.
You can also use retinoid creams after applying the vitamin C serum.

What it does (and what it doesn't).
The immediate effect is hydration and softness. Within 4–8 weeks, you’ll notice a reduction in the signs of sagging on the face and neck, with an overall effect of “skin that looks more lifted.”
Beyond the first 4–8 weeks, the effects are gradual and improve over time until they reach a peak, after which the treatment helps maintain the results.
Proteomic Serum works on:
- Nasolabial fold.
- Supralabial rhitidosis (barcode).
- Creases in the chin (marionette lines).
- Frontal and glabellar lines (forehead and frown lines).
- Expression wrinkles.
- Horizontal lines on the neck and vertical lines on the neckline.
The complete elimination of folds and wrinkles usually requires medical-aesthetic intervention and is beyond the scope of topical cosmetic treatments.

(*) Biopsy: collagen induction and its functional integration into the matrix architecture.
From plumpness to firmness.
A treatment that stimulates cells to produce more (pro)collagen falls short of achieving firmer skin if it does not also promote the conversion of this collagen into its mature and structurally functional form.
Only mature collagen (and elastin) is capable of integrating into the dermal matrix rather than remaining suspended within the skin.
Promoting the conversion of procollagen into mature collagen is the link between collagen induction and skin firmness.

Use it with SPF 50
Vitamin C does not replace sunscreen; rather, it complements it to provide comprehensive protection against photoaging. And tranexamic acid is the gold standard for lightening dark spots. However, sun exposure is the main cause of dark spots reappearing.
Without strong protection, UV rays continue to age the skin, and the improved complexion you wake up with each morning is lost as soon as you step outside.
This way, you help the serum work effectively, and the benefits really build up over time.

The serum is 100% water-based and spreads very easily. Just apply a small dab to each cheek, one to the forehead, and one to the neck and nape of the neck.
First, cleanse, then apply the serum, and finally the treatment cream. After applying the serum, apply the cream when your skin feels dry but not yet soft. In other words, apply the cream within 30–90 seconds of applying the serum.
It is important not to wait too long to apply the cream after the serum so that the rheological networks of the serum and cream can blend together and work in harmony.
Yes. This serum is a new version of the previous one. It’s our solution for improving skin firmness using new technologies.
The serum is specially formulated to be used in conjunction with creams designed to stimulate the production of structural proteins such as collagen I, III, and IV, and elastin. The cream stimulates protein production, while the serum promotes their maturation into functional forms.
Our Nutritive Cream and Gel Cream have been designed to work in perfect harmony with Proteomic Serum.
Twice a day, after cleansing your skin. If you use the vitamin C serum in the morning, there’s no need to apply the Proteomic Serum as well; save that for the evening.
Proteomic Serum is not only compatible with retinoids, butthe two work together very effectively.
Retinoid creams stimulate collagen production in cells. The serum helps collagen mature so that, once it has been released from the cell, it can integrate into the structures that give the skin its firmness.
