L39 - Day Serum for Blemishes

The bluish tint of this serum is naturally provided by copper PCA, recognized for its sebum-regulating properties, its astringent effect on pores, and its role in maintaining skin hydration.

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.

    My absolute favorite!!

    This is my favorite serum and is such a great product for sensitive, acne prone skin. It reduces sebum without drying, feels great, and layers beautifully under makeup.

    Tested and approved! Finally, the product I needed to reduce my imperfections; I haven't had any breakouts on my face since I started using it. Plus, it acts as a mattifying base before my tinted serum... in short, it's the best, I highly recommend it ++
