New · Barrier repair system
Healthy skin,
backed by science.
A calm, resilient barrier is where good skin starts. Multi-lamellar ceramides for dry, sensitive and reactive skin — no fragrance, no theatre.
Healthy skin,
Our promise
Skincare that respects
your barrier.
Three ceramide-rich formulas, nothing more: a toner that preps, a serum that repairs, an emulsion that seals. Built around what your skin actually needs — never a shelf of products that fight each other.
The tea in Yan Tee
Rooted in tea.
Refined in the lab.
Our name comes from tea. Green tea catechins and L-theanine are among the most studied antioxidants in skincare — calming, protective, and gentle enough for a compromised barrier. We pair them with multi-lamellar ceramides so the calming work and the repairing work happen together, not one after the other.
No fragrance · No essential oils · Dermatologist tested

Our story
Formulated in the lab.
Proven on real skin.
Every formula begins with the lipid architecture of healthy skin, then we test it on the people who need it most — dry, reactive, over-treated skin.

Asked by people with sensitive skin
What is a skin barrier, exactly?
It is the outermost layer of your skin — a wall of cells held together by lipids. When that wall is intact, water stays in and irritants stay out. When it is compromised, skin feels tight, stings, or flakes.
Which product should I start with?
If you are building a routine from scratch, start with a moisturizer. It is the one step that does the most for a struggling barrier — add cleanser and sunscreen next, everything else after.
Is it better for ceramides to absorb quickly?
Not necessarily. Fast absorption usually means a light texture, which is not the same as better barrier support. For very dry skin, a formula that stays slightly present on the surface often works harder.
Can I use these with actives like retinol?
Yes, but layer carefully — actives first on dry skin, then a barrier cream to buffer. If you are flaking or stinging, pull the active back before adding more moisturizer.
