When skin needs a reset

01

Skin looks tired

Busy weeks show up on your face first — as dullness and a lack of bounce.

02

Makeup won't sit right

Dry-feeling, uneven-looking skin makes foundation look patchy.

03

No time for a long routine

You want a visible pick-me-up without a ten-step evening.

Why UNI&CORE

What makes it different

01

2% pure vitamin C, stabilized

Real ascorbic acid — not a vitamin C scent — kept stable in a double-layer formula with a high hydration level.

02

100% TENCEL™ premium sheet

Made with water-save technology. The front keeps moisture and essence from escaping; the back propels essence toward the skin.

03

High-adherence fit

The sheet hugs every contour for a firmer, lifted feel — no slipping, no gaps.

Vita C Super Brightening Mask by UNI&CORE

Texture & Application

Essence you can feel working

A soft, well-soaked sheet delivers a light, watery essence. After removing the mask, pat the remaining essence into skin until absorbed.

  • Soft, fitted sheet
  • Light, watery essence
  • Comfortable 20-minute wear

How to Use

Your routine, step by step

  1. 1

    Cleanse

    Cleanse your skin thoroughly — ideally with the Vita C Enzyme Powder Wash.

  2. 2

    Apply for 10–20 minutes

    Apply the mask evenly over your face, darker side facing out, and remove it after about 10 to 20 minutes.

  3. 3

    Pat in the essence

    After removing the sheet, gently pat the remaining essence until absorbed.

  4. 4

    Finish

    Finish with a mist — and if your skin feels dry, an extra layer of cream. Then the Vita C 13.5 ampoule.

  • Tip: Place the sheet with its darker side facing out.

Caution: External use only. Avoid contact with eyes; if contact occurs, rinse thoroughly with water. Do not use on broken or irritated skin. Discontinue use if irritation or rash occurs. Keep out of reach of children. Store in a cool, dry place away from direct sunlight.

FAQ

Questions, answered

How often can I use the mask?

Two to three times a week works well for most people, or whenever skin needs a quick refresh.

Can I leave it on longer than 20 minutes?

We don't recommend it. Once the sheet starts to dry it can draw moisture back out of the skin.

Should I rinse after using the mask?

No need — pat the remaining essence into your skin and continue with your ampoule and moisturizer.

How many masks come in a box?

Each box contains 5 individually packed sheet masks, 0.56 oz (16 g) each.

What is the sheet made of?

A premium high-adherence sheet made from 100% TENCEL™ using water-save technology. It hugs the skin, keeps the essence from evaporating and pushes it toward the skin.

Which side faces out?

Place the sheet with the darker side facing out.
