Dr.Twenty Project 9 Serum 50ml

A 9-day calming project, formulated for sensitive skin

This calming serum was developed for skin that flushes easily after a full day of stress, and for those dealing with dryness and oiliness at the same time. It combines 9 key ingredients to address calming, barrier strengthening, and hydration all at once. Dermatologist-tested and formulated without 20 chemical ingredients, it's gentle enough for sensitive skin types to use with confidence.

Clinically proven calming and hydration benefits

In human application tests, redness improved by 75.19% immediately after use, and skin texture improved by 19.34%. With a 96-hour moisture-holding effect, hydration levels improved by 73.49%. A 2-week consumer study with 296 participants also showed meaningful results.

9 ingredients that deliver calming, barrier support, and hydration

Nine key ingredients work across three targeted areas to care for your skin.

• Calming: Mugwort Leaf Extract, Rosemary Leaf Extract, Allantoin
• Barrier strengthening: Panthenol (skin protection), Rose of Jericho Extract (resurrection plant), Trehalose
• Hydration: Hyaluronic Acid (moisture), Birch Sap, Xylitol

Free from artificial colorants and fragrances, it finishes fresh and non-sticky. Recommended for those experiencing deep dehydration, anyone needing to restore skin condition, or those looking for a calming hydration serum without the tackiness.

Use after toner, during your essence or serum step

This serum is designed to be applied after cleansing and toner, before your moisturizer. It brings together 9 key ingredients: mugwort leaf extract, rosemary leaf extract, and allantoin (soothing), panthenol, resurrection plant extract, and trehalose (barrier support), plus hyaluronic acid, birch sap, and xylitol (hydration). It's a versatile core step that fits seamlessly into any skincare routine.

A gentle daily serum for morning and evening use

Dermatologist-tested and rated non-irritating (0.00–0.25 range), this serum works beautifully in both your AM and PM routines. Clinical testing showed a 75.19% improvement in skin redness and a 19.34% improvement in skin texture. If using in the morning, always finish with sunscreen.

Dispense with the dropper and layer as needed

Dispense 1–2 pumps with the dropper and gently smooth over your entire face. On days when your skin feels especially dry, let the first layer absorb, then apply a second layer using the same method for a moisture-layering effect. Clinical testing confirmed an 89.42% improvement in skin hydration after 9 cumulative applications, with moisture retention lasting up to 96 hours.

Recommended pairings by skin concern

• Redness and sensitivity: Follow a soothing toner with 9 Serum, then seal with a lightweight moisturizer.
• Dryness and tightness: Layer the serum 2–3 times, then lock it in with a barrier-strengthening cream.
• Oily yet dehydrated skin: After 4 weeks of use, clinical results showed a 38.57% improvement in skin oil balance. Pair with a lightweight hydrating gel for best results.

Storage and usage notes

Store in a cool place away from direct sunlight, and avoid letting the dropper tip touch your skin directly. If you experience redness, itching, swelling, or other unusual reactions, discontinue use and consult a dermatologist. The formula is fragrance-free and colorant-free, making it suitable for fragrance-sensitive skin.
