COSRX Master Patch Basic: your discreet SOS helper for blemished spots

An unwanted blemish appears and you want a quick, hygienic solution? The COSRX Master Patch Basic hydrocolloid patches are your trusted ally and a K-beauty cult classic. They are your first line of defence for individual blemished spots: they protect the spot from being picked at and create a comfortable environment in which the skin can recover undisturbed.

The COSRX Master Patch Basic act like a protective shield. They absorb excess fluid from the blemish while creating a moist environment. The result: the spot looks calmer, visible redness eases and the skin can regenerate undisturbed. The patches are flat and adhere excellently, so you can wear them discreetly during the day or overnight.

The power of the ingredients: how your patch works

The secret of the COSRX Master Patch Basic lies in hydrocolloid technology. The core component, cellulose gum, forms a hydrocolloid gel known for its ability to absorb fluid. When you place the patch on a blemished spot, the hydrocolloid draws out excess secretion. A white, gel-like substance forms under the patch – a sign that it is actively working.

Further ingredients such as Hydrogenated Poly(C6-20 Olefin), Polyisobutene and Styrene/Isoprene Copolymer provide optimal adhesion and flexibility and form a protective cover. This protects the spot from external influences and from accidental touching and creates a moist environment in which the skin can settle undisturbed. The synergy of these components makes the patch so reliable.

How to add the Master Patches to your routine

Application is simple:

1. Preparation: Gently cleanse the affected area (e.g. with a mild cleanser) and dry it completely. Dry skin is important for optimal adhesion.
2. Selection: Choose a patch slightly larger than the spot to ensure maximum coverage.
3. Application: Carefully peel the patch off the film (avoid touching the adhesive side) and place it directly on the spot. Press it down lightly.
4. Let it work: Leave the patch on for at least 6 hours, ideally overnight. It turns whitish as it absorbs fluid.
5. Remove: Once the patch is completely white, peel it off carefully and dispose of it. Cleanse the area again and continue with your routine.

Pro tip: The Master Patches are perfect for overnight use. During the day they offer discreet protection under make-up.

Complete your routine for a clear complexion

For comprehensive care we recommend integrating the patches into a coordinated routine:

• Step 1 (cleanse): COSRX Low pH Good Morning Gel Cleanser - This gentle, pH-mild cleanser frees your skin of sebum and impurities without drying it out. A clean base is crucial for the patches to work.
• Step 2 (toner): COSRX AHA/BHA Clarifying Treatment Toner - This mild exfoliating toner helps remove dead skin flakes and keep pores clear.
• Step 3 (care after the patch): COSRX Advanced Snail 96 Mucin Power Essence - Gives your skin a soothed feel after use, provides intense moisture and supports the skin's protective barrier.

Can I apply make-up over the COSRX Master Patch Basic?

Yes, the patches are relatively flat and adhere well. You can carefully apply make-up over them. Take care not to shift the patch.

How long should I wear the patch?

Ideally 6-10 hours, best overnight. Once it looks whitish and swollen, it has absorbed the fluid and can be removed.

What is the difference between the Master Patch Basic and other COSRX patches?

The Master Patch Basic are the original round hydrocolloid patches that absorb excess fluid and protect the spot. Other variants such as the "Clear Fit Master Patch" are ultra-thin and matte for invisible daytime protection. The Basic version is your reliable all-rounder for quick care of individual spots.
