This 30ml booster serum is formulated to target hyperpigmentation, dullness, textural irregularity, and congested pores simultaneously, making it a high-efficiency solution for Pakistani skin that deals with multiple concerns at once.\u003c\/p\u003e\n\u003ch2\u003eKey Ingredients \u0026amp; Benefits\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTriple-action core: AHA + BHA + Vitamin C.\u003c\/strong\u003e \u003cstrong\u003eAHA (Glycolic and Lactic Acid)\u003c\/strong\u003e exfoliates the skin surface by breaking desmosome bonds between dead corneocytes, removing dulling surface cells to reveal brighter, more even-toned skin beneath. AHA is the primary treatment for PIH (post-inflammatory hyperpigmentation) caused by acne — the number one skin concern for Pakistani skin types. \u003cstrong\u003eBHA (Salicylic Acid)\u003c\/strong\u003e is oil-soluble and penetrates directly into pores to dissolve the sebum and dead cell mixture that causes blackheads, whiteheads, and congestion — essential for oily and combination Pakistani skin.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eVitamin C (Ascorbic Acid)\u003c\/strong\u003e provides dual-action benefits in this formula: it inhibits tyrosinase to prevent new melanin formation (stopping PIH at the source), and neutralises free radicals from UV exposure and pollution — two environmental stressors that are especially severe in Pakistani cities. The combination of AHA accelerating surface cell turnover, BHA clearing pores, and Vitamin C inhibiting melanin formation creates a synergistic brightening and clarifying effect that outperforms any single active used alone. \u003cstrong\u003eNiacinamide\u003c\/strong\u003e and \u003cstrong\u003eCentella Asiatica Extract\u003c\/strong\u003e soothe potential irritation from the actives.\u003c\/p\u003e\n\u003ch2\u003eSkin Concerns This Addresses\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#f0f0f0\"\u003e\n\u003cth style=\"padding:8px;border:1px solid #ddd;text-align:left\"\u003eSkin Concern\u003c\/th\u003e\n\u003cth style=\"padding:8px;border:1px solid #ddd;text-align:left\"\u003eHow It Helps\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd\"\u003eHyperpigmentation \u0026amp; dark spots\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd\"\u003eAHA removes pigmented dead cells while Vitamin C inhibits new melanin — dual-mechanism brightening\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd\"\u003eBlackheads and congested pores\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd\"\u003eBHA (salicylic acid) penetrates and clears pore congestion at the source\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd\"\u003eDull, uneven skin tone in Pakistani climate\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd\"\u003eTriple active combination significantly brightens and evens skin tone with consistent use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eHow to Use COSRX Refresh AHA BHA Vitamin C Booster Serum\u003c\/h2\u003e\n\u003cp\u003eApply 2–4 drops to clean skin after toning, 2–3 times per week in the PM routine (not daily — this is a booster serum with active ingredients). Spread evenly over face avoiding eye area, then follow with moisturiser. Do not use with retinol on the same night. Always use SPF 50+ the following morning as AHA increases UV sensitivity significantly. Beginners should patch test first and start with once per week before increasing frequency.\u003c\/p\u003e\n\u003ch2\u003eCOSRX Refresh AHA BHA Vitamin C Booster Serum in Your Korean Skincare Routine\u003c\/h2\u003e\n\u003cp\u003eUse this booster serum 2–3x weekly in your PM routine, alternating with retinol or other active nights. For maximum brightening of Pakistani PIH, pair the morning after use with COSRX Vitamin C serum (applied in AM before SPF) to continue the brightening action throughout the day. On days you use this serum, skip all other exfoliants and actives to avoid over-sensitising.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy COSRX from Korean Skincare Pakistan?\u003c\/h2\u003e\n\u003cp\u003eKorean Skincare Pakistan sources directly from COSRX's official Korean distributors and ships door-to-door from Seoul in 5–7 business days.
