    The serum doesn’t just sit on the skin, it absorbed easily and doesn’t have a runny consistency, doesn’t sting, fragrance free, and with consistent use with other kb products, you will glow and love your skin, always remember to wear your spf…

    Absorbs easily by my skin and does not sting even though it has a high percentage. The only downside is that it smells horrible, the smell does eventually disappear but it does distract from the whole experience.
