Barrier Care, Tested for Visible Comfort

3D Barrier Defence was developed around three dimensions of barrier care: hydration, repair support and protection.

In in-vivo testing on 30 volunteers, the formula was shown to visibly calm reactive and sensitive skin after one application.

A second in-vivo study showed visible improvement in the appearance of prolonged barrier damage after one use.

Barrier care should not feel complicated. It should feel consistent, comfortable and easy to keep using.

How to Build Your Barrier Care Routine

When skin feels dry, tight or sensitive, keep the routine simple first. Less is more until your skin feels stable again.

Step 1: Cleanse gently

Start with clean skin. Use Glycolipid Milk Cleanser if your skin feels dry, tight or easily stripped. Use Microalgae Balance Foaming Cleanser if your skin is oily or combination.

Step 2: Focus on barrier support

Apply 3D Barrier Defence to support hydration, comfort and daily barrier care.

Step 3: Introduce active serums slowly

If your routine includes Vitamin C Booster, B⁶ Brightening Formula or A⁶ Anti-Ageing Formula, introduce them gradually.

Start with one active serum step every other day, then increase frequency as your skin feels comfortable.

Vitamin C Booster, B⁶ and A⁶ can be mixed together in the palm of your hand and applied as one serum step — but if your skin feels compromised, do not start with all three at once.

Step 4: Finish with SPF in the morning

In the morning, finish with Urban Daily Defence SPF15 PA+++ to support daily protection.

Simple compromised-skin routine

Apply 3D Barrier Defence.
Finish with SPF in the morning.

Once your skin feels more stable, slowly add Vitamin C Booster, B⁶ or A⁶ back into your routine.

Sensitive Skin & Barrier Care FAQ

Which product should I start with?

Start with 3D Barrier Defence if your skin feels dry, tight, sensitive, reactive or uncomfortable.

Can I use A⁶ and B⁶ if my skin barrier feels weak?

You can, but introduce them slowly.

If your skin feels compromised, do not start with all active serums at once. Begin with barrier support first, then add active serums gradually as your skin feels comfortable.

Apply to clean skin after cleansing or after your serum step.

Use morning and night. In the morning, follow with Urban Daily Defence SPF15 PA+++.

If your skin is sensitive or reactive, introduce active serums one at a time.

Is 3D Barrier Defence suitable for oily skin?

Yes, oily skin can still feel dehydrated, reactive or barrier-stressed.

If your skin is oily or combination, choose Skin Balance System for a fresher routine that still includes barrier support.

How long should I keep the routine simple?

Keep the routine simple until your skin feels more comfortable and less reactive.

There is no fixed timeline. Let your skin guide the pace, and introduce active serums gradually.
