Source: Yesstyle

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: dipotassium glycyrrhizate.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3.6–5.5%
Dipotassium glycyrrhizateEffect: LowA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening~0.45–1.05%

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: allantoin, anhydroxylitol.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, bis-peg-18 methyl ether dimethyl silane.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Product summary

"MEDIHEAL - W. H. P White Hydrating Black Mask EX" is effective for: Anti-aging, Anti-blemish, Moisturizing and Evens skin tone

Ingredient callouts

  • A good concentration of Niacinamide (3.60% - 5.50%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
  • Dipotassium Glycyrrhizate in this product (0.55% - 1.25%) can also further help improve the skin barrier. It might be able to calm down inflammation and reduce sensitivity. Dipotassium Glycyrrhizate is an active compound from the licorice root.
  • In addition, this product contains Allantoin (1.30% - 1.90%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.
  • Humectants (allantoin 1.30% - 1.90%, xylitylglucoside 0.45% - 1.05%, trehalose 0.20% - 0.75%, arginine 0.10% - 0.40%, anhydroxylitol 0.40% - 0.95% and glycerin 2.70% - 4.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price
