Clean without the compromise - this is how cleansing should feel.

Benefits

Your barrier's idea of a good cleanse - A pH of 5.31 mirrors your skin's natural acidity, so impurities are removed without disturbing the protective layer that keeps moisture in and irritants out.

BHA that clears without the side effects - Betaine Salicylate is a gentler, skin-compatible form of BHA that refines texture and keeps pores clear - without the dryness or sensitivity that harsher salicylic acid can cause.

Light lather, zero tightness - Luxurious low-foam bubbles cleanse deeply but leave skin soft and hydrated - not stripped, not tight, just ready for whatever comes next in your routine.

Free from everything your skin doesn't need - No sulfates, no parabens, no artificial fragrance, no mineral oils, no silicone - hypoallergenic and gentle enough for twice-daily use on even the most sensitive skin.

Hero Ingredients

Betaine Salicylate (BHA)
What it does: A gentler, plant-derived form of BHA that exfoliates inside the pore to clear debris and refine skin texture with daily use. It delivers the clarity benefits of traditional BHA without the dryness or irritation that comes with harsher salicylic acid formulas.
Why we chose it: Effective daily exfoliation that's gentle enough for sensitive skin - this is exactly the ingredient story our cleanser range needed.

Tea Tree Leaf Oil (Melaleuca Alternifolia Leaf Oil)
What it does: A natural antibacterial that keeps skin surface clear and helps reduce impurity buildup. At the concentration used here it's targeted and effective without being stripping, working in harmony with the formula's low pH to support a naturally balanced skin environment.
Why we chose it: Natural clarifying actives with clinical credibility - Tea Tree earns its place in a formula this well-balanced.

Saccharomyces Ferment (Saccharomyces Ferment)
What it does: A K-beauty signature - fermented yeast extract packed with vitamins, minerals, and amino acids that nourishes and brightens the skin during cleansing, turning a basic step into a skin-conditioning one.
Why we chose it: Fermented ingredients in a cleanser are a marker of genuine K-beauty formulation thinking - this one delivers.

Skin Compatibility

Suitable for all skin types, including oily, acne-prone, dry, and sensitive skin. Particularly beneficial for those needing daily BHA support without irritation, and for anyone who typically experiences tightness or dryness after cleansing.

Free from sulfates, parabens, artificial fragrance, colorants, mineral oils, and silicone. Note: contains Tea Tree Oil - those with known sensitivities to essential oils may wish to patch test before daily use.

How to Use

Wet hands and face with warm water.
Apply a pea-sized amount to the palm and lather into a light foam.
Gently massage onto the face in circular motions, avoiding the eye and mouth area.
Rinse thoroughly with warm water.
Use morning and evening, after removing makeup. Suitable for face and body.

Pairs well with: a hydrating toner or essence applied immediately after, while skin is still slightly damp.

Studio Pick

Why we chose it: The COSRX Low pH Cleanser is one of the most consistently recommended entry-point K-beauty products for good reason - it is a well-formulated daily cleanser that respects the skin barrier rather than fighting it. The low pH + BHA combination is clinically sound, the fragrance-free formula is broadly inclusive, and it sets up every product that follows to perform better. We carry it because a cleanser this dialed-in is the foundation every routine in our catalog deserves.

Frequently Asked Questions

Is this cleanser suitable for dry and sensitive skin, or is it primarily for oily and acne-prone skin?

The Low pH Good Morning Gel Cleanser is formulated for all skin types, including dry and sensitive. The low pH (5.31) mirrors the skin's natural acidity, which means it cleanses effectively without disrupting the moisture barrier - the most common cause of post-cleanse tightness. It is also sulfate-free and fragrance-free, making it well tolerated by reactive and easily irritated skin types.

Should I use this in the morning, at night, or both?

This cleanser works well for both morning and evening use. In the morning it refreshes and balances the skin without over-stripping overnight sebum. At night, use it after an oil cleanser or makeup remover as a second cleanse to remove any remaining residue. Its low pH formulation is gentle enough for twice-daily use without depleting the skin's natural oils, which is what makes it such a reliable daily driver.

What is Betaine Salicylate and how is it different from regular salicylic acid?

Betaine Salicylate is a BHA derived from sugar beets rather than the synthetic salicylic acid found in most Western acne products. It works the same way - exfoliating inside the pore to clear debris and refine texture - but is generally gentler and better tolerated by sensitive skin. It's widely used in K-beauty precisely because it delivers BHA benefits at a daily-use strength without the dryness or irritation that higher concentrations of salicylic acid can cause.

Can I use this cleanser if I have active breakouts?

Yes - the Betaine Salicylate (BHA) in this formula gently clears pores and targets the congestion that contributes to breakouts, while Tea Tree Oil brings natural antibacterial support. The low pH environment also helps maintain the conditions in which healthy skin can recover. If your skin is severely inflamed or you are using a prescription acne treatment, it is worth checking with your dermatologist before adding a new BHA product to your routine.

How long will a 150ml tube last with daily use?

A pea-sized amount per cleanse is all that's needed to work up an adequate lather, so the tube goes a long way. Used once daily, a 150ml tube typically lasts 3-4 months; used morning and evening, expect closer to 2 months. Store at room temperature away from direct sunlight.
