Which active ingredient(s) should be used for oily skin?

• Serum No. 1 : Exfoliate with glycolic acid.

To tighten pores, it is highly recommended to use an astringent treatment such as a serum highly concentrated in glycolic acid, which has the ability to remove dead skin cells and thus facilitate the return of smoother and more unified skin.

Renowned for its exfoliating power, theglycolic acid rids the skin of dead cells, and performs a deep-cleansing action that helps combat blackheads. In addition to its peeling effect, it also stimulates the synthesis of hyaluronic acid and cellular renewal.

• Serum No. 2 : Mattifying with Azelaic Acid.

In order to limit the dilation of pores and the subsequent appearance of blackheads, there is only one solution: mattifying. In this regard, azelaic acid proves to be one of the most effective active ingredients, especially when it is concentrated in serum and combined with other ingredients known for their absorbent and purifying properties.

Derived from plants, this acid is known for its sebum-regulating, anti-comedogenic, and antibacterial properties. Indeed, this molecule works by regulating sebum production and reducing the formation of open comedones (blackheads), as well as limiting the proliferation of bacteria responsible for the appearance of pimples.

• Serum No. 3 : Purify with salicylic acid.

Extracted from willow bark, thesalicylic acid is suitable for all skin types (combination, oily, or sensitive), and stands out from other active ingredients through its numerous therapeutic virtues. In addition to its anti-inflammatory and analgesic properties, it provides many benefits, making it a highly sought-after active ingredient in the formulation of skincare products.

Thanks to its peeling effect, thesalicylic acid purifies the upper layer of the epidermis, exfoliates superficial cells, which softens and refines the skin texture. While promoting the elimination of dead cells, it also has anti-bacterial and astringent properties that notably allow it to:

• Regulating the overproduction of sebum;

• Enhancing the appearance of enlarged pores;

• Reducing inflammation in blemish-prone skin.

Non-irritating, this active ingredient concentrated in serum is suitable for the most sensitive skin types, particularly acne-prone skin. In addition to calming painful pimples, it visibly reduces redness.

In order to care for your oily skin, it is essential to choose suitable treatments and maintain a consistent routine to allow your skin to regain its balance. Consider cleansing it daily with a hydrosol or a purifying toner morning and evening instead of tap water, and do not skip the often neglected hydration step. Simply choose a cream that is suitable, non-greasy, and will protect your skin without adding more oil.
