I too have sensitive combination skin. The gel is lightweight, with a slight odor that does dissipate quickly. I use this peel every 10 days. I cleanse, use a microdermabrasion scrub then apply a light film of the peel. I leave it on for 10 minutes. Sometimes it tingles, other times it does not. It does not burn or feel uncomfortable and has caused absolutely no irritation to my sensitive skin. The product seems to penetrate my skin. After I remove, I immediately dry my face and apply HydroShield Serum. I wait a few minutes before applying a pea-size amount of the Triple Strength Advanced Wrinkle Smoother. After this treatment, my skin feels so soft and smooth. By the morning, it glows. I love this peel. There really is a noticeable difference in skin tone and texture. For those that may be concerned about the packaging, I can say it is a nice pump dispenser. It also opens so you can see inside.
