Why it exists

Over-exfoliated, over-treated and over it? Your skin doesn’t need another active. It needs a break.

Most routines strip the barrier, the thin layer of lipids that keeps water in and irritants out. When it breaks down, everything stings, flakes or flushes.

No. 3 does one job well. It restores the lipids your skin is missing, calms visible redness and gets out of the way, so the rest of your routine can work again.

Five ingredients.
Nothing to hide.

Every percentage is printed on the bottle. Formulated with a dermatologist and tested on 60 people with sensitive skin.

  1. 01

    Ceramide complex

    Three skin-identical ceramides refill the gaps in a weakened barrier.

  2. 02

    Colloidal oat 1%

    A skin protectant that soothes itch and visible redness within minutes.

  3. 03

    Niacinamide 2%

    A gentle dose that evens tone without the flushing higher strengths can cause.

  4. 04

    Olive squalane

    Weightless oil that locks in moisture and never feels greasy.

  5. 05

    Panthenol

    Pro-vitamin B5 helps skin recover faster after irritation or sun.
