The AHA BHA PHA LHA 35 Peel

COSRX The AHA BHA PHA LHA 35 Peel is a ten-minute at-home resurfacing treatment built on four different acid families at once. It is deliberately strong: COSRX recommends it for people who already know how their skin handles serious exfoliation, not for a first experiment with acids.

What it actually does

• Resurfaces in one short sitting. COSRX describes the texture-smoothing effect as immediate after a ten-minute application, rather than something that builds over weeks.
• Uses four acid types together. Alpha, beta, poly and lipo hydroxy acids are combined so the treatment lifts dead surface cells and works into congested pores in the same pass.
• Targets four specific complaints. Rough or bumpy patches, visible pores, dullness, and uneven tone and texture are the concerns the brand names.
• Makes pores look smaller and tone more even. The brand's claim is a clearer, more radiant complexion with less visible pore size after use.
• Pink for a reason. The natural pink colour comes from vitamin B12 in the formula, which COSRX says also helps keep irritation down during the treatment.
• Gel, not grit. The consistency is gel-like and spreads easily, so there is no physical scrubbing involved.

How to use

1. Once a week, at night. That is the frequency COSRX sets — resist the urge to do it more often.
2. Patch test first. The brand recommends it, and with a four-acid formula it is worth the two minutes.
3. Apply generously to clean, dry skin. Keep well clear of the eye area and the lips.
4. Ten minutes, maximum. Do not leave it on longer hoping for more — this is a hard ceiling, not a suggestion.
5. Rinse with lukewarm water. Then go straight to something simple and hydrating; skip other actives that night.

Before you buy: in Egypt's sun, follow any acid treatment with daily SPF. Freshly resurfaced skin burns more easily.

Questions

Can I use it more than once a week?

COSRX sets the frequency at once weekly, in the evening. Going beyond that with a four-acid formula risks a compromised barrier rather than faster results.

Why is it pink?

That shade comes from vitamin B12 in the formula. It is not added colour, and the brand notes the same ingredient helps calm irritated skin while the acids work.

Can I use retinol the same night?

We wouldn't. Keep peel night separate from retinol night and give your skin the evening off afterwards with a plain moisturiser.
