Numbuzin No.1 Pantothenic B5 Hyaluronic Active Clear Mask [26ml]

What it is

This is a Korean sheet mask by Numbuzin—specifically the No. 1 Pantothenic B5 Hyaluronic Active Clear Mask, in a 26 ml single-sheet format (or in some sets of 4 sheets). 
It is designed for acne-prone, sensitive, oily, or dehydrated skin that also needs soothing & hydration. 

Key Benefits

• Soothes irritated/red skin, especially when there are breakouts or inflammation. 

• Helps fade post-acne marks and redness, while controlling excess oil or sebum. 

• Provides good hydration and replenishment using multiple forms of hyaluronic acid, to help plump and support the skin barrier. 

• The mask sheet is fully soaked in essence, for an intensive effect rather than a light “just damp” sheet feeling. 

Key Ingredients & Their Roles

• Pantothenic Acid (Vitamin B5) / Panthenol: Helps calm inflammation, strengthen the skin barrier, and control oiliness (which is important for acne-prone skin).

• Niacinamide: Brightens skin tone, helps fade dark spots/post-acne marks.

• Hyaluronic Acid (and its different molecular weights / forms): Deep hydration, supports plumpness and skin comfort

• Other soothing and botanical extracts: For example, Houttuynia Cordata Extract, Centella Asiatica, licorice, etc – these contribute to calming and anti-inflammatory effects. 

How to Use

1. Start with a clean face (cleansing + toner/prep). 

2. Apply the sheet mask, aligning with your face and letting it adhere. 

3. Leave on for 10-20 minutes. Some sources say up to 40 minutes is possible for extra hydrating effect (until the sheet starts turning white or essence mostly absorbed) but generally 10-20 minutes is recommended. 

4. Remove mask and gently pat remaining essence into skin until absorbed. Do not rinse. 

5. Follow with your usual skincare (serum/moisturizer) if desired.

Who It’s Best For

• People with acne-prone skin, especially those dealing with breakouts, redness, post-acne marks.

• Those with sensitive skin that easily gets irritated or red.

• Skin types that get oily or combination but may also be dehydrated (often oily + tight/dehydrated combo) — the mask provides oil-control + hydration. 

• Anyone wanting a soothing “rescue” sheet mask for when skin is stressed, irritated, or in need of calming/up-conditioning.

Things to Keep in Mind / Tips

• Even though the mask is designed for sensitive/acne-prone skin, always patch-test if you have highly reactive skin.

• Sheet masks are supplementary — a consistent routine supporting your skin’s barrier, good cleansing, sun protection, etc., remains important.

• Because it includes active ingredients like niacinamide + B5 + botanical extracts, if you are using strong actives (e.g., acids, retinols) the mask can be a good “rest & soothe” step on recovery days.

• If after applying you feel stinging or discomfort (beyond mild cool/relief), remove the mask and rinse — skin may be too sensitive or compromised at that moment.

• For best results, use this sheet mask when your skin is visibly irritated or you know you'll have upcoming stress (e.g., after travel, environmental stress, etc.).

• After use, you may pat remaining essence onto neck or décolletage for extra benefit (some sources suggest this). 

Overall Impression

This mask stands out for combining soothing + hydrating + blemish-supporting functions in one. If you’re dealing with breakouts, redness, and want something more than just “moisturizing”, this is a strong option. The inclusion of B5/panthenol, niacinamide and multi-weight hyaluronic acid gives it a well-rounded profile for skin in need of calming and restoration.
