The science beyond youthful skin.

The formulation

Most cleansing bars are built to wash. Ours is built to treat. Every active in Stemcell Soap was chosen for one reason: a documented role in how skin renews, holds moisture, and keeps its tone even.

Six actives, one bar. Each is listed on the carton the way we list it here: plainly, with the job it does. Nothing in the formula is decorative.

Key actives

Six ingredients, six jobs.

  1. 01

    Snail Extract

    Helps repair skin, improve texture and reduce the appearance of fine lines.

    Snail secretion filtrate is naturally rich in glycoproteins, glycolic acid and hyaluronic acid, a combination prized in Korean skincare for supporting the skin's own renewal and moisture retention.

  2. 02

    Stemcell Culture Extract

    Supports skin regeneration and helps maintain skin elasticity and firmness.

    Plant stem cell culture extract is cultivated in controlled conditions to concentrate the protective compounds plants use to regenerate their own tissue, helping skin look firmer and more resilient.

  3. 03

    Niacinamide

    Helps brighten skin, even out skin tone and strengthen skin barrier.

    One of the most studied ingredients in modern dermatology, vitamin B3 supports the skin barrier, moderates the look of discolouration and leaves tone visibly more uniform.

  4. 04

    Collagen

    Helps improve skin elasticity and reduce appearance of wrinkles.

    Topical collagen forms a breathable, moisture-binding film that smooths the skin's surface, supporting suppleness and a plumper look.

  5. 05

    Aloe Vera

    Soothes and hydrates skin for a healthy and radiant complexion.

    Aloe barbadensis leaf extract calms, cools and hydrates, balancing the cleanse so skin never feels stripped.

  6. 06

    Oatmeal & Milk

    Gently exfoliates and nourishes skin, leaving it soft, smooth and supple.

    Finely milled oat kernel flour lifts away dull surface cells while milk proteins soften, creating a gentle polish suitable for daily use.
