Day Serum for Blemishes - 3% Succinic Acid + Copper PCA

Directions

Anti-Blemish

Blemishes are the result of an imbalance in the skin, primarily caused by three factors: an overproduction of sebum, an accumulation of dead skin cells on the surface (hyperkeratinization), and a proliferation of the bacteria Cutibacterium acnes.

This anti-blemish serum targets the three main factors responsible for imperfections. With its antibacterial and exfoliating properties, succinic acid slows the proliferation of C. acnes while limiting skin thickening. Meanwhile, copper PCA helps to rebalance sebum production. In synergy, these active ingredients not only reduce various types of blemishes but also refine skin texture.

Main active ingredients
Succinic Acid:
Derived from a biofermentation process, succinic acid is an organic compound with antibacterial properties. It specifically targets Cutibacterium acnes, the bacteria involved in the formation of blemishes, and inhibits its growth. Succinic acid also regulates the proliferation of epidermal cells, thereby limiting skin thickening. This helps prevent pore obstruction and minimizes the risk of new blemishes forming. Finally, succinic acid inhibits the release of certain pro-inflammatory molecules, reducing redness associated with inflammatory blemishes.
Copper PCA:
Known for its sebum-regulating effects, the copper-PCA complex is a valuable ally for combination to oily skin. By tightening pores and reducing the activity of sebaceous glands, copper helps to prevent blemishes. Additionally, it disrupts the metabolism of bacteria and inhibits their growth. PCA, on the other hand, promotes the synthesis of filaggrin, thereby strengthening the skin barrier and preventing water loss.
Ingredients
Aqua (Water), Pentylene Glycol, Succinic Acid, Arginine, Copper PCA, Urtica Dioica (Nettle) Leaf Extract, Xanthan Gum, Sodium Hydroxide, Hydroxyacetophenone, Glycerin.
