Description

Description:

The COSRX Refresh AHA BHA Vitamin C Booster Serum is a lightweight and fast-absorbing serum that is formulated to improve the overall texture and brightness of the skin. It contains a combination of three key ingredients - glycolic acid (AHA), betaine salicylate (BHA), and ascorbic acid (vitamin C) - which work together to exfoliate, unclog pores, and brighten the skin.

The glycolic acid and betaine salicylate are both exfoliants that work to remove dead skin cells and unclog pores. Glycolic acid is an AHA that is water-soluble, which means it is great for exfoliating the surface of the skin. Betaine salicylate is a BHA that is oil-soluble, which means it can penetrate deeper into the skin to unclog pores.

The ascorbic acid (vitamin C) is an antioxidant that helps to brighten the skin by reducing the appearance of dark spots and hyperpigmentation. It also helps to protect the skin against environmental stressors such as UV rays and pollution.

In addition to these key ingredients, the serum also contains hydrating and soothing ingredients such as panthenol and allantoin, which help to keep the skin moisturized and calm.

Overall, the COSRX Refresh AHA BHA Vitamin C Booster Serum is a great option for those looking to improve the overall texture and brightness of their skin, while also addressing issues such as clogged pores and hyperpigmentation.

How to use:

  • Prep your skin with toner after cleansing.
  • Dispense proper amount from the dropper and apply on cheeks and forehead.
  • Gently pat for better absorption.

Real orders, real skin, honest words.

★★★★★

Ordered on Tuesday evening, it was on my doormat Thursday. Everything sealed, with the Korean batch stickers still on.

Lisa, Antwerp
★★★★★

I asked which toner would work for my combination skin and got a proper answer within the hour. That is why I keep coming back.

Nour, Rotterdam
★★★★★

Cheaper than ordering from Korea once you count shipping and customs, and it arrives in days instead of weeks.

The bundle discount is applied automatically, no code hunting. Three products, 15% off, done.

Good prices and the order was exactly right. Packaging could be a bit sturdier but nothing was damaged.

Finally a shop that stocks the brands I see on TikTok without the 3-week wait.

Do I pay customs or import duties?

Not in the EU: prices include VAT and there are no extra charges at the door. Outside the EU, local import duties may apply and are paid by the customer.

How does the bundle discount work?

Add any 2 products to your bag and 10% comes off everything. Add 3 or more and it becomes 15%. It is applied automatically, no code needed, and you can mix brands.

Can I return it if it does not suit my skin?

Unopened products can be returned within 14 days for a full refund. For hygiene reasons we cannot take back opened skincare. Not sure it fits your skin? Message us before you order and we will tell you honestly.
