COSRX for Oily and Blemish-Prone Skin in Australia: AHA/BHA Toner, AC Collection, Pore Pads and a Simple Routine

There is a particular kind of skincare shopping that happens at midnight, under the bathroom light, with a phone in one hand. You are looking at your nose, your chin, the little rough patches, and typing in the first words that come to mind: blackhead, pimple patch, BHA liquid. If that is where you are, take a breath. The calmest, most sensible route is usually the simplest one, and COSRX built its name on exactly that.

A note on what we stock

Honesty first. Two of the most common COSRX searches, the BHA Blackhead Power Liquid and the pimple patches, are not currently in our range, so we will not pretend otherwise. What we do stock covers the same ground: clarifying toners, pads, gentle cleansers and light moisturisers. Check our COSRX collection for the latest.

The clarifying toner

The COSRX AHA/BHA Clarifying Treatment Toner ($21.99) is a classic for skin that looks congested or rough. It contains exfoliating acids, so go gently: patch test first, start once or twice a week, and always wear sunscreen the next morning. Skip it if your skin is irritated or sunburnt.

The pads

The COSRX One Step Original Blemish Pore Clear Pad ($39.95, 100 pads) is a swipe-on option for people who like a quick step. Use it on clean skin and avoid the eye area.

Cleansers that are kind to oily skin

Over-washing is one of the most common mistakes. Look for gentle, low-pH washes. The COSRX AC Collection Calming Foam Cleanser ($21.95), the COSRX Low pH Good Morning Gel Cleanser ($18.00) and the COSRX Red Rice Inositol Pore Clarifying Deep Cleanser ($28.95) are the usual picks. The COSRX Pure Fit Cica Clear Cleansing Oil ($41.00) is the oil step if you wear sunscreen or makeup.

Light moisturisers

Oily skin still needs moisture. The COSRX AC Collection Lightweight Soothing Moisturizer ($29.95) is the light finish. The COSRX Advanced Snail 92 All in One Cream (from $21.95) is a gel-cream feel many oily-skinned people enjoy. The COSRX The Niacinamide 15 Serum ($29.95) is a popular single-job serum. Introduce it slowly.

The calming step

The COSRX AC Collection Calming Liquid Mild ($29.95) is a gentler alternative to a stronger exfoliating step.

A simple routine

1. Morning: gentle wash, light moisturiser, sunscreen.
2. Evening: oil cleanser if you wore sunscreen, then a gentle wash.
3. Two nights a week: clarifying toner, then moisturiser.
4. Add one new product at a time.

When to see a professional

If your skin is painful, scarring or not improving, speak to a doctor or dermatologist. Cosmetic products are not a treatment for skin conditions.
