I've been enjoying Mary & May's products. They don't irritate my skin. I also like the easy to use packaging, it feels high end.
It has 1000 ppm Idebenone as an antioxidant and 20% Blackberry complex as another antioxidant. There is no fragrance, and the serum is slightly thick but flowy and not sticky. It hydrated my skin and left it softer and smoother throughout the day until the next day.
