How it works
Rich Moist Soothing Serum 80ml is KLAIRS's serum, a serum, layered after toner and before moisturizer. Its own ingredient list carries Sodium Hyaluronate at entry 2 of 36; Centella Asiatica Extract at entry 10 of 36; Sodium Ascorbyl Phosphate at entry 17 of 36; Citrus Paradisi (Grapefruit) Fruit Extract at entry 23 of 36, which is what the key-actives panel below is built from rather than the product name alone. A serum's thinner, faster-absorbing texture is built to sit under a heavier cream rather than replace one. Placement in the routine matters as much as any single ingredient, so this step is built to layer cleanly with what comes before and after it. Patch-test on the inner arm before a first full-face use, as with any new skincare step, and stop if irritation appears.
Key benefits
- Sodium Hyaluronate on the ingredient list at entry 2 of 36
- Centella Asiatica Extract on the ingredient list at entry 10 of 36
- Sodium Ascorbyl Phosphate on the ingredient list at entry 17 of 36
- Sized at 80 ml for the way this step is actually used in a routine
- Sourced for the Korean market and sold as the same formula, not a US-shelf reformulation
Key actives
Sodium Hyaluronate
Sodium Hyaluronate is the salt form of hyaluronic acid, the form most Korean formulas use for its ability to bind water at more than one molecular weight.
Centella Asiatica Extract
Centella Asiatica Extract is the calming botanical Korean skincare built an entire ingredient category around, and it is confirmed here on this row's own list rather than inferred from the brand's centella-forward branding.
Sodium Ascorbyl Phosphate
Sodium Ascorbyl Phosphate is a stabilized, phosphate-bound brightening derivative, a common choice in Korean formulas built for daily use rather than a short, intensive course.
Citrus Paradisi (Grapefruit) Fruit Extract
Citrus Paradisi (Grapefruit) Fruit Extract (grapefruit) gives this formula its citrus character and is a common choice in Korean toners aimed at a brighter, refreshed feel.
Panthenol
Panthenol, provitamin B5, is a humectant and soothing agent Korean formulas lean on to keep the rest of a formula feeling comfortable rather than tight once it sets.
What is Rich Moist Soothing Serum?
It is a serum from KLAIRS (80ml).
How do I use this serum?
Apply a few drops to clean skin after toner or essence and before moisturizer, morning and/or night, pressing it in rather than rubbing.
Can I use this with other serums?
Yes, layering thinnest to thickest texture is the usual rule; introduce one new serum at a time so you can tell what your skin is responding to.
