What the key ingredients do
-
Niacinamide
Vitamin B3. In a 12-week controlled study on aging facial skin, 5% niacinamide improved the look of fine lines, blotchiness and uneven tone.
Bissett et al., Dermatol Surg 2005 -
Panthenol (vitamin B5)
Helps skin hold moisture and supports barrier repair.
Proksch et al., J Dermatolog Treat 2017 -
Bakuchiol
Plant-derived retinol alternative. In a 12-week randomized trial, bakuchiol improved wrinkles and dark spots about as much as retinol, with less stinging and scaling.
Dhaliwal et al., Br J Dermatol 2019 -
Hyaluronic acid
Holds water in the skin. In a 60-day study, creams with hyaluronic acid improved hydration and elasticity.
Pavicic et al., J Drugs Dermatol 2011 -
Adenosine
In a 2-month placebo-controlled study of women aged 45 to 65, adenosine products smoothed lines around the eyes.
Abella, Int J Cosmet Sci 2006 -

Studied for skin repair and collagen support. Much of the evidence comes from lab work and small studies.
Pickart & Margolina, Int J Mol Sci 2018 -

Targets expression lines. A small study found less wrinkle depth after 30 days; larger studies are still few.
