Dr. Twenty Project Clearnic White Mask Serum Toner 3-Piece Set

A brightening ritual powered by pure British vitamin C

If dull, uneven skin tone is your concern, this is for you. The Clearnic White 3-Piece Set brings together a toner, serum, and mask — all certified as brightening functional cosmetics by Korea's Ministry of Food and Drug Safety. Each formula is built around 99% pure vitamin C sourced from the UK, micronized for better absorption. The lineup also features niacinamide for tone correction, arbutin for radiance support, and paper mulberry root extract for hydration and vitality — a targeted blend designed to restore luminosity.

Dermatologist-tested and formulated for sensitivity

The toner passed a low-irritation human application test with 31 participants, and both the mask and serum have completed dermatologist testing. Free from 20 chemical ingredients including parabens and sulfates, the line is gentle enough for sensitive skin. A patented microbiome complex of Bacillus, Lactobacillus, and Aspergillus ferments helps support skin's microbial balance, while a barrier-strengthening trio of ceramides, cholesterol, and fatty acids works alongside 17 amino acids to nourish and fortify.

A step-by-step approach to brighter, healthier skin

This isn't just about brightening — it's about building skin resilience from the ground up.

Toner: A generous 500 ml bottle that works as a wipe toner, hydrating mask base, or refreshing mist

Serum: A high-potency formula for targeted brightening care

Mask: A close-fitting sheet that delivers active ingredients with seamless adherence

Ideal for anyone dealing with dark spots, hyperpigmentation, or a dull complexion. Use all three together to maximize your brightening results.

Toner-Serum-Mask, Your Brightening Routine Order

This 3-piece set follows the classic K-beauty sequence: toner → serum → special care (mask). After cleansing, prep your skin with the White Toner, follow with the White Serum for targeted care, then finish with the White Mask 2–3 times a week to maximize brightening results.

A Vitamin C Line You Can Use Morning and Night

Formulated with pure British vitamin C and niacinamide (a tone-evening ingredient), this line is gentle enough for both AM and PM use. If you apply it in the morning, always finish with sunscreen. While vitamin C helps protect against UV-induced oxidation, pairing it with SPF amplifies its effectiveness.

How Much to Use and How to Apply Each Product

• Toner: Saturate a cotton pad and gently sweep across your entire face, or pour into your palms and pat in lightly. The generous 500ml size also makes it perfect for DIY cotton sheet masks.
• Serum: Dispense 2–3 drops with the dropper, spread from the center of your face outward, then press gently with your palms to help it absorb.
• Mask: After cleansing, apply the sheet at the toner step, leave on for 15–20 minutes, then remove. Pat in any remaining essence until fully absorbed.

Tailored Combinations for Your Skin Concerns

If dullness and uneven tone are your main concerns, use the toner and serum daily, adding the mask 2–3 times a week. For stubborn dark spots or hyperpigmentation, layer an extra drop of serum directly onto those areas for intensive targeting. When dryness is an issue, seal in the serum with a rich moisturizer to lock in hydration.

Storage and Precautions for Vitamin C Products

Vitamin C can oxidize when exposed to light and air, so store your products in a cool place away from direct sunlight. Avoid using retinol products at the same time, as this may cause irritation—consider alternating morning and evening routines. If you experience redness, itching, or any unusual reactions, discontinue use and consult a dermatologist.
