KLAIRS - Rich Moist Soothing Serum 80ml

Hydration is the least glamorous word in skincare and the most load-bearing, and the Rich Moist Soothing Serum is KLAIRS’ case for taking it seriously. A generous 80ml of cooling, deeply moisturizing serum, it lowers the skin’s surface temperature while replenishing water — the foundation under every other result you want, from all-day glow to makeup that cooperates.

Why It Works

The mechanism is refreshingly honest: calm skin down, fill it with water, keep it there. The formula lowers surface temperature as it hydrates — heat and dehydration travel together on stressed skin — and builds the moisture level that changes everything downstream. Well-hydrated skin secretes less excess oil, holds a smooth radiance through the day, and lets makeup work with it rather than cling to dry patches. It is the serum for people whose real concern is “everything looks slightly off,” because dehydration usually is the everything.

How to Use

Morning and evening after toner: a full dropper pressed over the face, then cream to seal. It layers under actives peacefully and makes an excellent buffer beneath stronger treatments. If your skin drinks it and asks for more, the dehydration diagnosis is confirmed — see dehydrated vs dry skin for the full picture.

Who It’s For

Every skin type, genuinely — dehydration does not discriminate. Oily skin gets the counterintuitive fix (more water, less grease), dry skin gets the middle layer it is missing, and makeup wearers get the prep step that outperforms most primers. Companions in Dry & Dehydrated Skin.

FAQ

How is this different from a moisturizer?

The serum delivers the water; the moisturizer keeps it in. Layer this under the Rich Moist Soothing Cream and the two halves of hydration are covered — supply and seal.

Can oily skin use a hydrating serum?

Oily skin often benefits most: well-hydrated skin secretes less excess oil, so adding water can visibly calm the shine cycle. The cooling, weightless texture suits it perfectly.

Does it really help makeup last?

Hydrated skin is the honest secret of good makeup days — foundation grips evenly instead of catching on dry patches. Serum, cream, SPF, one minute between layers, then base.
