EST.NU GLU¹C² GLOW DAILY MASK 

1) Whitening Functional Ingredient ‘Niacinamide’:
– Niacinamide: A type of vitamin B3 that inhibits the activity of the enzyme tyrosinase involved in melanin synthesis. It prevents melanin from moving to the stratum corneum, thus assisting in whitening and reducing pigmentation.
– Contains 2% of the functional ingredient.
– Definition of whitening functional cosmetics:
(1) Cosmetics that help whiten the skin by preventing melanin pigmentation on the skin, thus inhibiting the formation of blemishes, freckles, and similar concerns.
(2) Cosmetics that lighten the color of melanin pigmentation already deposited on the skin, aiding in skin whitening.

2) Wrinkle-Improving Functional Ingredient ‘Adenosine’:
– Adenosine: An amino acid-derived protein component found in cells. It promotes the activity of fibroblasts in the dermis, inducing extracellular matrix and collagen synthesis, which helps with elasticity and wrinkle improvement.
– Contains 0.04% of the functional ingredient.
– Definition of wrinkle-improving functional cosmetics: Cosmetics that provide elasticity to the skin, thus alleviating or improving skin wrinkles.

3) Glutathione:
– Glutathione is a potent antioxidant synthesized within cells through the combination of three amino acids (glutamic acid, cysteine, glycine).
– It inhibits the activity of the enzyme tyrosinase, resulting in the suppression of melanin production.
– It plays a role in converting Eumelanin (dark color) into Pheomelanin (light color) during melanin synthesis.

4) Vitamin C Derivative (3-O-Ethyl Ascorbic Acid):
– Exerts antioxidant effects, protecting cells from harmful oxygen species.
– As a derivative of vitamin C, it is less irritating to the skin compared to pure ascorbic acid.

5) 17 Types of Amino Acids:
– Including cysteine, glycine, serine, glutamic acid, aspartic acid, leucine, alanine, lysine, arginine, tyrosine, phenylalanine, valine, threonine, proline, isoleucine, histidine, methionine.
– Contains the component ‘cysteine,’ which is part of glutathione, providing a synergistic effect.
– Amino acids make up 40% of the natural moisturizing factors in the skin’s stratum corneum, supplying moisture and nutrition.

6) Vitamin Tree Extract:
– Extracted from the vitamin tree, rich in nutrients like vitamin C and E, which contribute to clear and healthy skin tone.

7) PHA (Gluconolactone):
– PHAs have larger molecules and are less easily absorbed by the skin, making them gentle exfoliating agents that help remove dead skin cells and refine the skin texture.

8) Three Types of Hyaluronic Acid:
– Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate.
– These are natural moisturizing factors present in the skin’s epidermis, responsible for attracting and retaining moisture, keeping the skin well-hydrated.

2) Step 2: Inhibition of Eumelanin Production:
– Glutathione, Cysteine: Conversion of Eumelanin to Pheomelanin.
3) Step 3: Inhibition of Melanin Pigment Migration:
– Niacinamide: Inhibition of Melanin Pigment Migration.
4) Step 4: Removal of Already Deposited Melanin Pigments:
– PHA: Promotes skin tissue turnover by removing dead skin cells.
