The ingredients and why they matter
Development formula · Coming soon. Ingredient highlights, not a complete list; request full ingredients, including the preservative.
Niacinamide · vitamin B3
4% niacinamide
A skin-conditioning vitamin studied for uneven tone and visible signs of aging. Included to support a more even-looking complexion; results depend on the complete formula.
N-acetyl glucosamine · NAG
2% N-acetyl glucosamine
An amino sugar included alongside niacinamide for more even-looking tone. Studies of the pairing in other moisturizers do not establish results for this serum.
Panthenol · provitamin B5
2% panthenol
Attracts and holds water to support soft, comfortable-feeling skin. Complements the serum’s hyaluronic acid.
Ceramide complex
3% ceramide complex
Supplies skin-conditioning lipids to complement water-binding ingredients and support moisture retention. The stated percentage refers to the supplied complex, not pure ceramides.
