Benefits

Intensive Wrinkle Reduction: Utilizes patented Vitamin U (Methylmethionine) to support skin cell regeneration and significantly improve the appearance of deep wrinkles and fine lines.

Enhanced Skin Elasticity & Firming: Formulated with the Syn-ake peptide complex, which provides a “lifting” effect by relaxing facial muscles and improving overall skin density and firmness.

Brightening & Tone Correction: Contains Niacinamide and Adenosine to brighten dull complexions, even out skin tone, and help fade hyperpigmentation or dark spots.

Deep Hydration & Barrier Repair: Uses a combination of Ceramides, Hyaluronic Acid, and a 3-Peptide complex to restore the skin’s moisture barrier and prevent trans-epidermal water loss.

Plumping (Volufiline): Includes Volufiline (derived from Anemarrhena Asphodeloides root), which helps improve skin volume and plumpness, targeting sagging areas.

 

Recommendations for skin types and conditions

Mature & Aging Skin: Specifically targets sagging, wrinkled skin and loss of elasticity using a patented Vitamin U complex and peptides.

Dull & Tired Skin: Revitalizes a “crumbly” or fatigued complexion to restore a youthful glow and even skin tone.

Sensitive & Delicate Skin: Formulated without parabens and artificial fragrances to safely soothe inflammation and support the skin barrier.

Dry & Dehydrated Skin: Provides deep hydration through ceramides and hyaluronic acid, making it ideal for skin that easily dries out or generates flakes.

Active Ingredients

Vitamin U (Methylmethionine): A patented sulfur-containing amino acid derived from broccoli and seaweed that promotes rapid cell regeneration, smooths fine lines, and soothes inflammation.

Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate): A synthetic peptide that mimics snake venom to relax expression lines and provide a lifting effect.

EGF (Epidermal Growth Factor): Specifically sh-Oligopeptide-1, it stimulates cell growth and division to strengthen the skin barrier and reduce wrinkle depth.

Palmitoyl Pentapeptide-4: A low molecular weight bioactive material that boosts collagen and extracellular matrix (ECM) biosynthesis to improve skin elasticity.

Niacinamide: A Vitamin B3 derivative that brightens the complexion, evens skin tone, and helps fade pigmentation.

Ceramide NP: Restores the skin’s lipid barrier to prevent moisture loss and maintain long-lasting hydration.

Adenosine: A functional anti-wrinkle ingredient that enhances collagen and elastin production. 

Hyaluronic Acid & Polyglutamic Acid: High-performance humectants that attract and lock moisture deep into the skin layers.

 

How to Use

Cleanse your face thoroughly and even out skin texture using a toner.

Apply a small amount (about 2–3 drops) of the serum to your forehead and cheeks.

Gently spread the serum along your skin’s texture lines, moving from the center of your face outward. Gently pat the skin to aid full absorption.

Follow with a moisturizer to lock in the nutrients. If using in the morning, always finish with sunscreen. 

Frequency: Recommended for use twice daily, both morning and night, for optimal anti-aging and rejuvenating results.

Storage: Keep the bottle tightly closed in a cool, dry place away from direct sunlight to maintain the stability of the active ingredients.

Safety: If you have highly sensitive or allergy-prone skin, it is recommended to perform a patch test on a small area for 24–48 hours before full application.

 

Precautions

Before use, perform a patch test on the back of your hand to check for possible allergic reactions. Keep out of reach of children, away from direct sunlight, at room temperature. In case of contact with eyes, rinse with water. If an allergic reaction occurs, discontinue use and consult a doctor.
