Dear Klairs - Rich Moist Soothing Serum 80ml

If your skin runs hot, reactive, and perpetually thirsty, the Dear Klairs Rich Moist Soothing Serum is one of those rare finds that addresses all of it at once. This cult K-beauty serum has been quietly winning over sensitive skin types for years, and a recent reformulation made it even better — removing essential oils entirely to make the formula genuinely appropriate for the most reactive skin.

Sodium Hyaluronate leads the formula for deep, lasting hydration, supported by Betaine and Polyquaternium-51 (a skin-identical phospholipid that mimics the skin's own moisturising lipids) for a plumping, barrier-supportive effect that goes beyond surface-level moisture. Dimethyl Sulfone (MSM) is an underrated anti-inflammatory ingredient that helps with redness and skin sensitivity over time.

The botanical complex is impressive: Centella Asiatica and Licorice Root Extract work together for soothing and brightening, Scutellaria Baicalensis (Skullcap) Root Extract provides antioxidant and antimicrobial support, and Beta-Glucan deeply soothes and reinforces the skin barrier. Aloe Barbadensis Leaf Extract, Portulaca Oleracea, and Althaea Rosea Flower Extract add further layers of calm and comfort.

Sodium Ascorbyl Phosphate (a stable, gentle Vitamin C derivative) and Tocopheryl Acetate bring antioxidant protection and contribute subtle brightening over time. The serum also contains a full profile of amino acids — Lysine, Proline, Theanine — to support skin structure and resilience.

Fragrance-free and newly reformulated to be even more gentle. Sul Skin recommends this as the first serum for anyone rebuilding their skin after a reaction, or for anyone whose skin just seems to dislike everything.
