The essential edit

Your skin barrier does not need more drama. It needs lipids.

When skin feels dry or uncomfortable, more water-based actives are not always the answer. UN/02 focuses on replenishing surface lipids with a 70% squalane base and two lightweight emollients. The anhydrous format keeps the formula deliberately short, reduces dependence on a conventional water-phase preservative system and layers beneath UN/03 without introducing unnecessary fragrance or botanical clutter.

What it does

  • Softens dry, rough or tight-feeling skin by replenishing lightweight surface emollients
  • Reduces the sensation of moisture loss and supports the barrier without adding another exfoliating or stimulating active
  • The water-free, four-ingredient formula provides smooth slip and can be adjusted by amount according to climate and skin type

What earns its place

  • 70% squalane for lightweight lipid replenishment
  • Caprylic/capric triglyceride for softness and slip
  • Coco-caprylate/caprate for a light, elegant finish
  • Tocopherol supports formula stability

What it leaves out

  • No water—the formula is a concentrated lipid step rather than another watery serum
  • No added fragrance or essential oils, which are unnecessary for barrier support
  • No exfoliating acids, retinoids or trend-led active cocktail
  • No added colour

Designed for

  • Dehydrated or easily unsettled skin
  • Use beneath moisturiser
  • A simple morning and evening routine

Formulation decisions

  • Barrier support before trend-led complexity
  • A shared airless pack helps protect the formula
  • No added fragrance

The un/extra ritual

Four facial steps.
One clear order.

AM
  1. UN/01 Soft Wash
  2. UN/02 Barrier Serum
  3. UN/03 Essential Cream
  4. UN/04 Daily Sunscreen SPF 30
PM
  1. UN/01 Soft Wash
  2. UN/02 Barrier Serum
  3. UN/03 Essential Cream

UN/05 is the separate daily body step: apply to clean, completely dry underarms.

How to use

Use it
with intention.

Apply one to two pumps after water-based treatments and before UN/03 Essential Cream. Smooth over face and neck. Use morning and/or evening; reduce the amount in humid weather or on oilier areas.

Barrier care does not always require a long active list. A carefully balanced emollient blend can provide the softness and lipid support that dry, uncomfortable skin is asking for.
