The Vitamin B3+ Stay Ageless Serum delivers concentrated niacinamide (vitamin B3) in a fat-soluble, bioavailable form, designed to strengthen the skin barrier and reduce visible signs of aging, making it tolerable even for those with sensitive skin.

Niacinamide is one of the most important nutrients for skin longevity. It fuels energy production inside cells, reinforces the skin barrier, calms inflammation, and promotes collagen synthesis. This silky, fast-absorbing serum combines a blend of age-defying messenger peptides, powerful plant extracts, amino acids, and antioxidants to visibly tighten, brighten, and revitalize tired or aging skin.

What Makes Us Different

While many products with niacinamide rely on water-based, lower-potency versions that can’t penetrate as deeply, the Vitamin B3+ Stay Ageless Repair Serum uses a lipid-friendly form of Vitamin B3 that has been clinically tested for superior absorption and tolerance.

This formulation was designed to work in collaboration with the SkinHappy Solution Series, delivering expert results for aging skin without irritation or disruption to the skin's barrier.

Recommended For:

• Dull or aging skin
  Fine lines and uneven texture
  Sensitive or reactive skin
  Daily protection for the skin barrier

How to Use

Apply to clean, dry skin once or twice daily. For best results, pair with the SkinHappy Solution Series and a broad-spectrum UVA/UVB sunblock. Products may be mixed together for a smooth application.
