Acne: Definition and Causes.
According to the S.F.D. (French Society of Dermatology), 15 million people in France are affected by acne problems, including 3.3 million aged over 15 years. This skin disorder affects approximately 80% of teenagers (of which 15% present severe acne) and nearly 25% of adults, particularly women. It can appear both on the face and certain parts of the body (chest, back, buttocks...). The primary reason for consultation with a dermatologist, this skin condition can lead to a lack of self-confidence and significant psychological distress.
This chronic inflammatory disease develops at the level of the pilosebaceous follicles-sebaceous glands: the sebaceous glands secrete sebum that is too thick or in too large a quantity, which clogs the pores and leads to the formation of pimples and/or blackheads. This condition is then referred to as dysseborrhea.
This condition is often triggered by stress, pollution, and hormones. An unhealthy lifestyle (lack of sleep, smoking, unbalanced diet, poor hygiene...) can also trigger or worsen this sebum alteration, leading to the appearance of blackheads or blemishes. Moreover, in this fat-rich environment, a bacterium usually present in small amounts on the skin, Propionibacterium acnes, proliferates, which triggers an inflammatory response in the skin.
The benefits of salicylic acid on acne-prone skin.
Salicylic acid treatments are particularly recommended for taking care of oily skin and acne-prone skin. This active ingredient works on several levels:
Skin Cell Renewal :
Salicylic acid activates skin regeneration. Thanks to its keratolytic properties, it removes dead cells on the skin's surface and inhibits the pore blockage that leads to acne. Thus, it effectively combats the appearance of blackheads and tightens pores for a brightened and unified complexion.
Prevention of Bacterial Development :
The surface of the epidermis can be colonized by harmful microorganisms that disrupt the microbiota and lead to redness, irritation, or sometimes painful pimples. Thanks to its properties as anantiseptic, salicylic acid prevents the proliferation of harmful bacteria, such as Cutibacterium acnes, a microorganism responsible for the inflammatory reactions of acne.
Pain Relief :
An acne-prone skin often leads todiscomfort. Pimples can cause tingling, itching, and burning sensations. The soothing virtues of salicylic acid alleviate symptoms related to inflammation. Indeed, salicylic acid plays a role in the arachidonic acid cascade and inhibits the synthesis of prostaglandins E2, molecules responsible for inflammatory and painful effects. In the treatment of acne, it thus soothes painful pimples and visibly reduces redness.
