The Verdict

If your acne is accompanied by severe redness, sensitivity, or a damaged barrier, start with COSRX. Their soothing formulas will calm the skin while gently treating the blemishes. If your skin is resilient but you suffer from stubborn, cystic acne or severely enlarged pores that require aggressive treatment, Medicube is your best bet for fast, clinical results.
