“DESCRIPTION Numbuzin No.5 Glutathione Vitamin Tone-up Sun Serum hydrates and protects the skin. Protects the skin from harmful UV rays.”

Source: Lila Beauty

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: arginine, glycerin.

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, dimethicone.

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

PanthenolHero· HumectantEffect: HighHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.45–0.65%

Diisopropyl sebacateKey active· EmollientEffect: MediumHelps soften the upper layer of the skin without creatng a greasy finish~6.3–7.7%

Hippophae rhamnoides oilKey active· EmollientEffect: HighA good emollient.

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: alpha-arbutin, glutathione

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.

Alpha-arbutinKey activeEffect: HighMight help reduce hyperpigmentation when used regularly over a long period of time. Is more effective than beta-arbutin~0.45–0.65%

Side benefit · Adenosine, Ubiquinone + 4 more

Works well

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

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.

Ingredient callouts

This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.45% - 0.65%) it cannot have a noticeable benefit for the skin.
Adenosine 0.50% - 0.80%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
Humectants (glycerin 0.30% - 0.55%, panthenol 0.45% - 0.65% and arginine 0.45% - 0.65%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
