Physical scrubs address surface cell sloughing, but persistent congestion requires a lipophilic mechanism. Paula’s Choice 2% BHA Liquid Exfoliant remains a definitive benchmark in topical formulation because Beta Hydroxy Acid is uniquely oil-soluble. Unlike AHAs, which work primarily on the upper epidermal layer, Salicylic Acid penetrates the lipid-rich environment of the pore to dissolve keratinized debris and hardened sebum from within. Application Logic: Introduce gradually—2 to 3 evenings per week on dry skin following clearance. Follow immediately with a lipid-replenishing compound to maintain optimal hydration balances, and enforce rigorous daytime photoprotection. 🛒 Formulation details and purchase link available below.
