Both are foam cleansers, but they're built for different jobs entirely: one is an antibacterial, exfoliating daily cleanse, the other a calming, zero-active option, and the price gap between them is real, not marginal.
Why compare these two specifically
The price difference here is the most notable feature: SKIN1004 costs over 50% more per mL than COSRX, for a formula with no active ingredient at all. That's worth examining directly rather than assuming the pricier option is doing more.
Price per milliliter
COSRX runs $0.09 per milliliter ($14.00 for 150mL). SKIN1004 runs $0.14 per milliliter ($17.00 for 125mL). SKIN1004 costs roughly 55% more per mL.
Antibacterial exfoliation vs. pure calming
COSRX builds around betaine salicylate (BHA) alongside tea tree leaf water, positioned for oily and acne-prone skin. SKIN1004 skips actives entirely, centering on Madagascar-sourced centella asiatica alongside sodium hyaluronate and cacao extract, positioned for gentle, soothing daily use.
The price gap tracks fragrance status, not formula complexity
SKIN1004's higher per-mL price isn't buying more active ingredients, its list is actually shorter than COSRX's. What it does buy is confirmed fragrance-free status. COSRX contains fragrance via its tea tree leaf water. If exfoliation isn't the goal, the premium on SKIN1004 is really a fragrance-free premium, not a formula-depth one.
Our take
If you're oily or acne-prone and want antibacterial exfoliation at the lower price, COSRX is the clear pick. If you want a purely calming, zero-active, fragrance-free cleanser and the higher per-mL cost isn't a concern, SKIN1004 delivers that specifically, not a more complex formula.
COSRX Low pH Good Morning Gel Cleanser: $0.09/mL. Antibacterial tea tree plus BHA exfoliation, the lower-cost pick for oily or acne-prone skin.
SKIN1004 Madagascar Centella Ampoule Foam: $0.14/mL. Confirmed fragrance-free with no active exfoliant, a roughly 55% premium over COSRX for a simpler, purely calming formula.
