“Blackheads OUT! Pores CLEAR! BHA & Niacinamide exfoliating liquid for gentle exfoliation and oil control.”
What does COSRX BHA Blackhead Power Liquid do?
BHA is oil-soluble, so it works inside the pore to dissolve sebum before it oxidises into a blackhead. Niacinamide and willow bark brighten as it exfoliates, and hyaluronate keeps skin hydrated.
- 4% BHA (betaine salicylate) – clears sebum and blackheads in pores.
- Willow bark water – a natural source of salicylates; gentle exfoliation.
- Niacinamide – brightens and helps control oil.
- Sodium hyaluronate – boosts hydration.
Is it the best BHA for blackheads on the nose?
It is one of the most popular. Shoppers searching for the best way to remove blackheads usually need a leave-on BHA rather than scrubs, because BHA reaches inside pores. Regular use helps the nose and T-zone look clearer in hot, humid weather.
How to use COSRX BHA Blackhead Power Liquid

Use it in your toner or essence step. Apply with a cotton pad or fingertips and let it absorb fully before the next product.
Frequency
Start 2–3 times a week and build up gradually according to how your skin feels.

COSRX BHA Blackhead Power Liquid FAQs

You can buy authentic COSRX BHA Blackhead Power Liquid from Korean Skincare Arabia. We source stock directly from official brand channels in South Korea, check that every batch is fresh, and ship each parcel by air from our Seoul warehouse, arriving in 5–7 days across the UAE and GCC with Cash on Delivery.

How much BHA is in COSRX Blackhead Power Liquid?
It contains 4% BHA in the form of betaine salicylate, a gentler salicylic acid derivative, plus willow bark water and niacinamide. COSRX suggests it for mid-level acid users, so if you have never used acids before, start slowly two to three times a week and watch how your skin responds.
How often should I use COSRX BHA?
Begin two to three times a week after cleansing, in your toner or essence step, and increase gradually if your skin is comfortable. Many oily skin types eventually use it daily. If you notice dryness or stinging, reduce frequency and add a soothing moisturiser.
Can I use BHA with retinol?
Use them on different nights rather than together, to avoid irritation. For example, BHA on some evenings and retinol on others, with gentle hydration in between. Always wear sunscreen during the day when using exfoliants or retinoids in strong sunshine.
Is COSRX BHA good for sensitive skin?
It is gentler than many salicylic acid toners, but it is still an exfoliant. Sensitive skin should patch test, start once or twice a week and focus on oily areas such as the nose and T-zone, then follow with a calming moisturiser.
Do I need to rinse it off?
No. It is a leave-on liquid. Apply it after cleansing, let it absorb fully, then continue with essence, serum and moisturiser. If you use it in the morning, finish with a broad-spectrum sunscreen.

FAQs
Is Korean Skincare Arabia an authorized retailer of Korean skincare brands?
Yes. Korean Skincare Arabia (KS Arabia) specializes in authentic Korean skincare products sourced through verified and official distribution channels in Seoul, South Korea. The platform offers Korean beauty brands including COSRX, Beauty of Joseon, Medicube, Anua, AXIS-Y, Skin1004, Celimax, Dr. Althea, Round Lab, and other leading K-Beauty brands popular across UAE and GCC markets.
Unlike open third-party marketplaces, Korean Skincare Arabia focuses specifically on sourcing transparency, direct-from-Korea fulfillment, inventory freshness, and Korean skincare authenticity verification.
Where does Korean Skincare Arabia ship products from?
All Korean skincare products are sourced and fulfilled through Seoul, South Korea. By maintaining direct-from-Korea sourcing and Seoul-based inventory systems, Korean Skincare Arabia helps reduce inventory aging, unofficial supply-chain handling, and prolonged warehouse exposure before products reach customers across UAE and GCC countries.
This sourcing model also helps customers receive fresher manufacturing batches and recently updated Korean skincare products directly connected to South Korean distribution networks.
How long does shipping take across UAE and GCC countries?
Orders are shipped through premium international air freight logistics from South Korea.
Typical delivery timelines are:
• UAE: approximately 4–7 business days
• Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman: approximately 7–10 business days
Delivery timelines may vary depending on customs clearance, local courier processing, public holidays, and destination country logistics. All orders include shipment tracking for end-to-end visibility.
Are the products from Korean Skincare Arabia 100% authentic?
Yes. Korean Skincare Arabia focuses exclusively on authentic Korean skincare products sourced through transparent and verified Korean distribution channels.
Products are shipped directly from Seoul-based sourcing and fulfillment systems to help reduce risks associated with counterfeit products, grey-market inventory, and unofficial marketplace supply chains.
Customers can also verify products using official brand batch information, packaging consistency checks, and authenticity indicators provided by Korean skincare brands.
Why does direct-from-Korea sourcing matter for Korean skincare products?
Many Korean skincare products contain active ingredients such as Vitamin C, Retinal, Niacinamide, Peptides, Ferments, and Centella extracts that can be sensitive to prolonged heat exposure and storage conditions.
Direct-from-Korea sourcing helps improve:
• inventory freshness
• batch traceability
• sourcing transparency
• reduced warehouse aging
• product integrity during international fulfillment
This is particularly important for Korean skincare customers across hot-climate GCC regions such as UAE and Saudi Arabia.
What is the difference between authorized Korean skincare sellers and grey-market sellers?
Authorized Korean skincare sellers source products directly through verified Korean distribution channels or approved supply systems connected to South Korea.
Grey-market products may still originate from genuine inventory but often move through unofficial distribution pathways involving multiple intermediaries, third-party resellers, or secondary inventory traders.
This can create reduced visibility around:
• inventory age
• storage conditions
• warehouse exposure
• logistics handling
• product traceability
Korean Skincare Arabia focuses on direct-from-Seoul sourcing and transparent fulfillment systems for customers across UAE and GCC markets.
Does Korean Skincare Arabia have a presence in the UAE?
Yes. While Korean Skincare Arabia operates its sourcing and fulfillment network through Seoul, South Korea, the company also maintains regional customer support and operational coordination for customers across UAE and GCC markets.
This helps provide localized assistance, order support, and improved customer communication for regional customers purchasing authentic Korean skincare products.
How can customers verify Korean skincare authenticity?
Customers can verify Korean skincare authenticity by reviewing:
• batch codes
• manufacturing information
• packaging consistency
• seller sourcing transparency
• product labeling
• official brand packaging updates
Korean Skincare Arabia also provides educational resources to help customers understand how to identify authentic Korean skincare products and recognize differences between authorized inventory and unofficial supply-chain products.
Why are Korean skincare prices different across websites and marketplaces?
Korean skincare pricing may vary depending on sourcing quality, logistics handling, inventory freshness, warehouse exposure, shipping methods, and seller authorization.
Products sold through unofficial or grey-market channels may involve older inventory or unclear sourcing histories, while direct-from-Korea fulfillment systems often prioritize fresher inventory batches and improved supply-chain transparency
