We use the same amount of skin care, so no, it doesn't bother him! lol
We are both still fighting acne (even though we are in our mid-20's), so we each have our own facial wash, and we share one acne treatment. I also use a second acne treatment just for myself, while hubby adds a moisturzer for some extremely dry, peeling skin on his nose. (I've never figured out why his nose gets so dry, but the rest of his face is still oily and acne prone!)
