Description
CUSKIN Protective Sun Serum SPF 50+ PA++++ with Vitamin U and B12, 50g.
A tri-functional sun serum that protects the skin from UVA/UVB rays. This is an exceptionally lightweight formula with vitamin U, which provides the skin with a sensation of freshness and hydration. UV filters across the full UV spectrum → Five photostable ingredients that block UVA and UVB rays, blended in an optimal ratio to effectively protect the skin from ultraviolet rays, helping to maintain healthy and radiant-looking skin,
To protect the skin from sun rays, it is important to use protective products, as ultraviolet radiation breaks down collagen, which leads to premature skin ageing. When exposed to UV rays, cells begin to intensively produce melanin, which results in the appearance of pigmentation spots. The protective serum with five advanced chemical filters ensures reliable protection against UVA and UVB rays and features a high SPF50+ PA++++ level, helping to effectively protect the skin from the harmful effects of ultraviolet rays.
The formula is enriched with antioxidants for additional protection against free radicals, and also incorporates peptides, volufiline and vitamin U, which help prevent premature ageing and maintain skin firmness. The key ingredient is cyanocobalamin (vitamin B12), also known as the "pink vitamin". This multifunctional component improves skin condition, protects blood vessels from couperose, strengthens the skin's barrier function, soothes, hydrates, brightens, stimulates collagen production and helps combat acne and dermatitis.
The product holds the OCEAN FRIENDLY certification, meaning it is safe for marine ecosystems. It contains no synthetic dyes — the natural pink tint is provided by vitamin B12. The lightweight texture does not weigh down the skin even in warm weather, leaving a feeling of freshness and hydration. If needed, the product can be easily reapplied — it absorbs quickly and leaves no stickiness or white cast.

Active ingredients:
5 modern photo-stable chemical filters (Uvinul T 150, Uvinul A Plus, Mexoryl SX, Mexoryl XL, Tinosorb S) – next-generation filters that provide comprehensive protection against the harmful effects of UVA rays (which trigger premature ageing) and UVB rays (which cause sunburn). These filters remain stable for up to 8 hours in urban conditions without oxidising.
Cyanocobalamin (Vitamin B12) is a multifunctional ingredient that effectively soothes redness and reduces the visibility of capillaries. It controls sebum production and reduces inflammation, making it a common choice in the treatment of dermatitis, rosacea, and acne. It also strengthens the protective barrier, moisturises, brightens, combats wrinkles, and protects the skin from free radicals.
Niacinamide is a potent antioxidant that performs multiple functions: it protects cells from photo-damage, reduces glycation, strengthens the protective barrier, and promotes dermal matrix synthesis, helping to combat ageing. It also brightens pigmentation and corrects acne.
Vitamin E is a powerful antioxidant that softens the skin and reduces inflammation. It slows down the ageing of skin cells.
Vitamin U (Methylmethionine) – a patented CUSKIN ingredient, a unique source of amino acids. Promotes rapid skin healing, reduces wrinkles and improves elasticity.
Volifuline – stimulates the volume of fat cells (adipocytes) and improves skin density. It stimulates collagen synthesis, resulting in shorter and less deep wrinkles, and more elastic skin.
A complex of 6 peptides (Hexapeptide-9, Hexapeptide-11, Palmitoyl Pentapeptide-4, Palmitoyl Tripeptide-1, Tripeptide-1, Copper Tripeptide-1) – stimulates collagen synthesis and contributes to the skin rejuvenation process. Increases firmness and density, reduces wrinkles and prevents new ones from forming. The complex with copper peptide not only acts against ageing but also reduces sensitivity and has an antimicrobial effect.
Adenosine is a powerful ingredient that improves collagen and elastin synthesis, reduces wrinkles, and slows down skin ageing.
Panthenol – possesses strong healing and soothing properties. Regenerates damaged cells and reduces irritation.
Phytosterols, hydrolysed lecithin, allantoin, and a hyaluronic acid complex of varying molecular weights – ensure long-lasting hydration, protect the lipid barrier, and restore the hydrolipidic balance.
Usage: Apply the product 20 minutes before going outdoors. Avoid contact with mucous membranes.
