CUSKIN Vitamin U Sun Serum SPF 50+/PA++++ 50g

CUSKIN CU: Vitamin U Sun Serum SPF50 PA++++ is a multifunctional 3-in-1 sunscreen serum that provides broad-spectrum UV protection while helping to prevent premature skin aging and deliver long-lasting hydration.

It improves skin firmness and elasticity, reduces the appearance of fine lines and wrinkles, and helps slow visible signs of aging. The lightweight formula nourishes and softens the skin, prevents dryness and flaking, and strengthens the skin's moisture barrier.

The serum contains no artificial colorants. Its natural pink hue comes from Vitamin B12 (Cyanocobalamin). It leaves no white cast.

The formula helps protect the skin from pigmentation and sunburn with a combination of photostable chemical UV filters that provide reliable protection for up to 8 hours in everyday urban conditions:

1. Uvinul A Plus (Diethylamino Hydroxybenzoyl Hexyl Benzoate) – protects against UVA rays.
2. Uvinul T 150 (Ethylhexyl Triazone) – provides high-performance UVB protection.
3. Tinosorb S (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) – broad-spectrum UVA and UVB filter.
4. Mexoryl SX (Terephthalylidene Dicamphor Sulfonic Acid) – protects against UVA rays.
5. Mexoryl XL (Drometrizole Trisiloxane) – oil-soluble broad-spectrum UVA and UVB filter.
   

Main active ingredients:

• Vitamin U – a patented active ingredient and amino acid derivative that helps repair damaged skin, smooth the appearance of wrinkles, and soothe irritation and inflammation.
• 6 Peptides – help improve skin regeneration, reduce the appearance of wrinkles, and promote firmer, smoother-looking skin. Argireline®, a botulinum-like peptide, helps relax facial muscle tension to minimize the appearance of expression lines.
• Volufiline™ (Anemarrhena Asphodeloides Root Extract) – helps improve skin density and volume for a plumper-looking complexion while reducing the appearance of wrinkles.
• 7 Types of Hyaluronic Acid – penetrate multiple layers of the skin to deliver deep hydration while forming a moisture-locking barrier that helps prevent water loss.
• Niacinamide (Vitamin B3) – brightens pigmentation, helps prevent new dark spots, regulates excess sebum, reduces shine, and strengthens the skin's protective barrier.
• Panthenol (Vitamin B5) – soothes redness and irritation, reinforces the skin barrier, prevents moisture loss, and supports skin recovery.
• Cyanocobalamin (Vitamin B12) – hydrates, calms the skin, helps reduce inflammation, strengthens capillaries, and supports clearer-looking skin.
• Phospholipids – help retain moisture within the skin and reinforce the skin's natural protective barrier.

Suitable for all skin types.
