What is COSRX Refresh AHA BHA Vitamin C Booster Serum?

The COSRX Refresh AHA BHA Vitamin C Booster Serum combines three powerful skin-brightening and clarifying actives — AHA exfoliation, BHA pore-cleansing, and Vitamin C brightening — in a single concentrated serum. 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.

Key Ingredients & Benefits

Triple-action core: AHA + BHA + Vitamin C. AHA (Glycolic and Lactic Acid) 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. BHA (Salicylic Acid) 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.

Vitamin C (Ascorbic Acid) 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. Niacinamide and Centella Asiatica Extract soothe potential irritation from the actives.

How to Use COSRX Refresh AHA BHA Vitamin C Booster Serum

Apply 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.

COSRX Refresh AHA BHA Vitamin C Booster Serum in Your Korean Skincare Routine

Use 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.

What is the COSRX Refresh AHA BHA Vitamin C Booster Serum price in Pakistan?

Can I use COSRX AHA BHA Vitamin C Booster Serum daily?

No — this is a potent triple-active serum and should be used 2–3 times per week maximum. Daily use of AHA+BHA+Vitamin C combined will over-exfoliate and irritate Pakistani skin. Alternate with gentle hydrating products on non-use nights.

Does the triple-active serum help with Pakistani PIH and dark spots?

Yes, significantly. The combination of AHA (removing pigmented cells), BHA (clearing congestion that causes new PIH), and Vitamin C (inhibiting melanin formation) creates a comprehensive brightening protocol. Most users see visible improvement in 6–8 weeks.

Is COSRX Vitamin C Booster Serum safe for sensitive Pakistani skin?

Start slowly — patch test first, then begin with once per week. The inclusion of centella asiatica and niacinamide helps buffer sensitivity, but this remains a potent serum. If significant tingling or redness occurs, reduce frequency.
