Active ingredient
AHA
INCI · Alpha Hydroxy Acids
Alpha Hydroxy Acids are a family of water-soluble acids, including glycolic and lactic acid, used for gentle surface exfoliation. They help release dull, loose surface cells to reveal a smoother feel and a brighter, more refined-looking complexion.
Mechanism in detail
What AHA does
They dissolve the bonds holding loose surface cells, supporting gentle exfoliation and surface renewal.
Where it helps
Concerns AHA addresses
Acne
Acne is rarely just acne. It is the anxiety before a meeting, the photo you skip, the makeup routine that started as "a little" and is now twenty minutes. The marks last longer than the breakouts, and they carry the breakout's weight long after the skin has healed. The Acnemed range is the salicylic-acid-led routine BIOSAR built for the full cycle — clearing active blemishes, calming the inflammation that follows, and reducing the marks the breakouts leave behind. Designed under dermatological supervision.
Dullness
Dull skin is the visible loss of luminosity, where the surface appears flat, grey, or fatigued instead of light-reflective. The underlying causes are dead-cell accumulation on the stratum corneum, dehydration, microcirculation impairment, and oxidative stress. Effective treatment combines gentle exfoliation (alpha- and beta-hydroxy acids), antioxidant serums (vitamin C, niacinamide), barrier hydration, and consistent broad-spectrum SPF. Visible improvement typically arrives within two to four weeks of a structured routine, matching the natural cell-turnover cycle of healthy skin.
