Most over-the-counter chemical exfoliants operate on single-acid mechanisms left on the face overnight. The Alpha Beta system uses a two-pad sequence that mimics clinical chemical peels. Step 1 delivers a blend of alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). Glycolic acid penetrates deep into the epidermis to dissolve the protein bonds holding dead keratinocytes together. Lactic acid works alongside it, exfoliating surface debris while functioning as an osmotic humectant. Salicylic acid, a lipid-soluble BHA, cuts directly through sebum inside the sebaceous unit to unclog pores and clear microcomedones. Malic, mandelic, and citric acids round out the matrix to target surface texture.
Leaving unneutralized AHAs on the skin lowers cutaneous pH to approximately 3.5, triggering sustained cellular shedding. Left unchecked, this drop compromises lipid bilayer integrity and causes transepidermal water loss (TEWL).
Step 2 intervenes directly. Formulated with sodium bicarbonate, this second pad rapidly restores cutaneous pH back toward physiological norms (5.0, 5.5). The neutralizer does more than shut down acid activity. It infuses the treated tissue with active soothing ingredients, including colloidal sulfur, green tea extract, retinol, and resveratrol. This rapid shutoff explains why patients prone to erythema often tolerate these pads when traditional leave-on toners cause flaking and stinging.
