A sunscreen serum with an ultra-light texture that combines a high level of UV protection with the benefits of a skincare product for comprehensive daily skin care.

The formula of Needly Youth Core Sun Serum is based on a complex of four next-generation chemical filters: Uvinul® A Plus, Uvinul® T 150, Tinosorb® S, and Mexoryl® SX. Thanks to their complementary properties, these filters provide effective broad-spectrum protection against UVA and UVB radiation, preventing the appearance of signs of photoaging, pigmentation, and skin damage.

Each filter acts at different wavelengths, creating a synergistic effect: the active molecules absorb, scatter, and partially reflect ultraviolet rays. Their exceptional photostability allows them to retain their protective properties even under prolonged exposure to sunlight, without losing their effectiveness throughout the day.

The serum consists of 77% moisturizing base, which maintains optimal hydration levels without leaving a film or feeling sticky. Hydroxyethyl urea restores the skin’s natural ability to retain moisture, reducing dryness and tightness. Ectoine, a natural cellular defense molecule, reduces transepidermal water loss and improves the skin’s barrier function. The skin looks fresher and more well-groomed, with a healthy glow.

TanTan Core Complex™—an extract from the shells of acorns from the evergreen oak, a tree common in Asia—is responsible for combating the effects of photoaging and soothing the skin. This active ingredient works specifically to preserve the skin’s youthfulness: it stimulates regeneration processes, improves skin tone, and restores the density and elasticity of the epidermis. It also soothes irritated skin and reduces redness.

The serum has a light, pleasant texture, absorbs quickly, and leaves no white residue. It works well as a makeup primer and increases makeup longevity by 39%.
