Frequently Asked Questions
You've got questions, we've got answers
Is BB Burst a skin tint, a tinted moisturizer, or a foundation?
BB Burst is a fresh take on all of the above, but is most similar to the experience of a tinted moisturizer. It has an innovative, refreshing gel cream texture that delivers a hydrating burst of active skincare, light buildable coverage and a smooth, hydrated, natural finish. It offers the prettiest tint + serious skincare in one!
How should I apply BB Burst?
Let your skincare fully absorb and then apply with fingers like a tinted moisturizer. Build to desired coverage level. Pair with Kosas Revealer Concealer in areas needing more attention.
What is the coverage?
BB Burst has light, buildable coverage that looks like your skin, but better.
What is the finish?
BB Burst offers a smooth, hydrated, natural finish.
