No.5 Vitamin Spotlight Sheet Mask

The Numbuzin No.5 Vitamin Spotlight Sheet Mask is designed for skin marked by dark spots and a dull complexion. If your current routine isn't enough to fade these marks, this sheet mask provides a targeted, concentrated treatment.

Its formula combines niacinamide, vitamin C in two forms (sodium ascorbyl phosphate and ascorbic acid), and glutathione, three active ingredients known for their ability to even out skin tone. Hyaluronic acid, polyglutamic acid, and allantoin provide hydration while the mask is on, without leaving a sticky residue.

According to the brand, skin appears brighter and the complexion more even after use. This mask is suitable for normal, dry, or combination skin seeking radiance, as a supplement to an existing routine.

Unlike a concentrated serum used daily, this sheet mask offers an occasional treatment, designed for a quick radiance boost before an event or as a weekly supplement.

How often should I use the No.5 Vitamin Spotlight mask?

The brand does not specify an exact frequency on its official product page. Generally, a sheet mask like this should be used once or twice a week, as a supplement to your usual routine. There is no need to use it every day to benefit from its action on dull skin and dark spots.

Can I use this mask with vitamin C or retinol?

This mask already contains vitamin C (ascorbic acid and sodium ascorbyl phosphate) and niacinamide. Avoid using it on the same day as a highly concentrated pure vitamin C serum. With retinol, space out the applications to reduce the risk of irritation on already stressed skin.

How long does it take to see results on dark spots?

The brand states that its brightening effect is visible from the first use, without publishing any quantified tests or panel results on its official product page. For an effect on more established dark spots, repeated use over several weeks is generally necessary.

What should I do after using a sheet mask?

Once the mask is removed, gently pat your face to help the remaining essence absorb, without rinsing. You can then follow up with your usual serum or cream to lock in the hydration, without waiting for your skin to dry completely.

Where can I buy the Numbuzin No.5 Vitamin Spotlight Sheet Mask in France?

Holy Skin ships this mask from France, with no customs fees, and guaranteed authenticity. You can also find the brand's other skincare products in the Numbuzin collection.
