What is different about this stage

The prevention decade. Skin still recovers quickly, which makes it the cheapest possible time to build sunscreen and barrier habits.

What damaged moisture barrier looks like here

Stinging with products that used to be fine, new sensitivity, patchy flaking — the signature of an over-exfoliated or over-worked barrier.

Ingredients to lean on

🧱 Ceramides🧱 Cholesterol🩹 Panthenol (Pro-B5)🌿 Centella (Cica)🏜️ Ectoin
⚠️ Be careful with: All acids, retinoids and scrubs until skin stops stinging
💡 Tip: Barrier repair is mostly subtraction. Strip the routine back to cleanser, a simple moisturiser and sunscreen for two to four weeks — adding another product is usually the wrong instinct.
