What it is
Neem bark extract is a natural plant extract derived from the bark of the neem tree (Azadirachta indica). It contains various bioactive compounds, including nimbin, nimbidin, and flavonoids, which are thought to contribute to its soothing and antioxidant effects.
How it works
In a cosmetic product, neem bark extract works primarily as a soothing agent, helping to calm temporary skin irritation and redness. Its antioxidant compounds also help neutralize free radicals, which can otherwise contribute to premature skin aging. It does not have strong antimicrobial activity like neem oil, but it may offer mild purifying benefits.

Cons and cautions
Limited topical research
Most studies on neem focus on its oil or leaf extracts, so the specific benefits of bark extract in skincare are less well-documented.
