Dermalogica Smart Response Serum is a multi-tasking serum for all skin types. It manages your skin’s changing needs on a microscopic level, so you don’t have to. Our skin is constantly sending us signals: on a macroscopic level, we perceive them as redness, fine lines, dark spots and dehydration. If we could look more closely, we would see that these skin conditions can actually be caused by damage that occurs on a microscopic level. When skin is damaged, it tends to change its structure and chemical makeup, either as a result of the damage or as a form of self-defense. By the time we notice signs of skin distress, the damage may already be happening. Smart Response Serum, however, sees what you can’t.
