This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.

Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.

Not sufficient moisturizing for dry skin, a little does not go a long way
This didn't make me break out, didn't pill, and plays nicely with the cream/liquid makeup formulas in my collection. That's about as good as it gets. I have dry skin in a dry environment and this was totally insufficient to use alone as a moisturizer, even during the day under a moisturizing sunscreen, and I would wake up Show more

Review

This didn't do much for my skin. I pilled on my forehead and under my chin and neck. The moisture is ok for a bit, but then my skin dried out pretty quickly. Hydration did not last all day. Also not sweat proof. Sad, I really liked the idea of this moisturizer.
