Salicylic Acid Salicylic Acid (BHA)
Salicylic acid is an organic BHA (beta-hydroxy acid) derived from white willow bark, one of the best-studied ingredients in anti-acne dermatology. Unlike AHA acids, it is oil-soluble, so it penetrates oily pores and clears them from within, dissolving sebum, blackheads and excess dead skin cells. It also acts keratolytically, anti-inflammatorily and antibacterially, inhibiting the growth of Cutibacterium acnes bacteria responsible for acne lesions. It effectively reduces breakouts, papules, open and closed comedones, evens out skin tone and minimises the appearance of pores. It is the gold standard in skincare for oily, problematic and acne-prone teenage skin — featured in Christina's signature Comodex line.
ANTI-ACNE2% salicylic acid: 47% reduction in acne lesions and 38% reduction in comedones over 12 weeks (Zheng & Yin, 2015, n=46).
This lipophilic BHA penetrates sebum and pores, dissolving keratin plugs. It inhibits 5-lipoxygenase and COX-2, reducing inflammation. It acts bacteriostatically against C. acnes.
