Why This COSRX Skincare Trio is Unlike Anything Else for Your Skin
If you’ve been feeling like your skincare has been a bit meh recently, then allow me to introduce you to something really game-changing. I’ve experimented with a ton of products and routines over the years, but when I tried COSRX’s three-step routine, I felt as though my skin was essentially reset. I found the experience powerful enough that I did a full, lengthy wear test and unboxing video on this glorious products, if you would like a visual reference and a closer look.
This amazing trio ranges from a glow-enhancing serum to a skin-loving cleanser to a ceramide-rich moisturizer. Between them, these products will provide your skin barrier with everything it needs to bounce back, gently, effectively, and with real results.
Step 1 / LOW pH GOOD MORNING GEL CLEANSER
Cleansers are a must-have, they can make or break a skincare routine, and this gel cleanser is a classic for good reason.

Why it works:
- Acidic pH level: Helps maintain healthy skin by restoring the skin’s optimal pH level to ensure it stays balanced and protected.
- Mild surfactants: Light surfactants provide a mild and gentle cleanse while making your skin feel clean, less the hefty lather that can wash away your skin’s natural oils.
- Safe for all skin types: With a patented gentle formula that boasts the positive effects of bionutrients, this cleanser is even safe for those with sensitive skin.
- Formulated with botanical extracts: In addition to tea tree oil, this product also contains natural BHA to cleanse, soothe, and detox the skin, which makes it great for those with breakouts or sensitivities.
Best Use:
It’s great for your morning cleanse routine, but also gentle enough to be used for a second cleanse in the evening if you want a truly clean skin before bedtime.
Tip: To get the optimal benefit, put the cleanser on moist skin and massage in for 60 seconds. This is where you get all the good stuff from the cleanser. You’ll never feel tight or dry after using, just completely refreshed and ready for the day.
Step 2: The 6 Peptide Skin Booster Serum
We are going to talk through that now.

This richly textured heavy hitting serum is formulated with an impressive cocktail of six Peptides: powerful, yet safe skin restoring, skin firming, relaxing and repairing actives. The peptides include the SH-Polypeptide-121 for Collagen Boosting & Plumping, Copper Tripeptide-1 to retexturize, Dipeptide Diaminobutyroyl Benzylamide Diacetate for excess sebum & pore care, Oligopeptide-68 for brightening, Palmitoyl Tripeptide-8 to soothe & reduce skin sensitivity, and Acetyl Hexapeptide-8: Smooth Fine Lines & Firmness. If you have trouble with, say:
– Dull: With the serum, lifeless skin gets a shot of vitality.
– Hyperpigmentation: It helps even out skin pigment, so your complexion appears less blotchy.
– Pores: The peptides reduce the appearance of pores for a more even looking complexion.
– Oily mess: It balances oil, so you feel refreshed but not slimy.
Texture Check:
This serum has a pleasant, non-sticky texture. It goes on very lightly and soaks into the skin easily, and mixes well with anything you put on top of it, such as makeup. Consider it the primer for the rest of your skin-care routine. It preps the skin to better absorb the products that follow, making them all the more effective.
Step Three: Apply Ceramide Skin Barrier Moisturizer
This last step to the routine is all about sealing in hydration and strengthening your skin barrier, and this is especially important if you tend to have sensitive skin, are feeling dry today, or have exfoliated recently.

What I noticed:
- Supremely smooth application: This rexaline moisturizing face cream is a breeze to apply to the face, melting in like icing on cake.
- No greasy residue: To the very end, it won’t leave a greasy residue; instead, your skin will feel exceptionally well-nourished.
- Silky dewy finish that does not look powdery: Infused with moisturizing and hydrating ingredients, the powder goes on without looking dry and flaky.
This is the sort of moisturizer that you’ll want to just keep touching your face all day (which you obviously shouldn’t, so your dirty/oily fingers stay off your face!).
Why This Combination Works
It’s these three items (and a common purpose) that come together in perfect harmony, resulting in a skincare routine that’s greater than the sum of its parts. Alone, they can target difference skin concerns, but together? It’s a real chef’s kiss moment.
Product What It Targets
- Cleanser: Impurities, excess oil, sensitivity
- Peptide Serum: Dullness, Discoloration, Pores
- Moisturizer: Dryness, barrier repair, hydration
These are not conflicting products, they work together and in harmony to produce that balance in your skin that you have been looking for, they give your skin the big present that it has been longing for long, long time – the present of long term health.
