Dimethicone is a silicon oil that is man-made in a laboratory. It is used in personal care products as an anti-foaming agent, skin protecting agent, and skin and hair conditioner.
Manufacturers like to use it because it makes their products easily spreadable. You know that feeling of a primer or BB cream smoothly gliding over your skin? That’s Dimethicone! It also forms a barrier on the skin. This effect can fill in the fine lines and wrinkles on the face, which is why it’s often used in makeup primers. But, that artificial silicon coating on the outside of your skin causes several issues. It traps everything under it (including bacteria, sebum, and impurities-YUCK) which usually leads to increased breakouts and blackheads. It also prevents the skin from performing its normal activities, like sweating, temperature regulating, sloughing off dead skin cells, etc. You’re also creating a dependency on the coating product which disrupts the skin’s own natural hydration process, which in the end increases dryness, making fine lines and wrinkles more noticeable.
Prolonged exposure to dimethicone can actually increase skin irritation and is listed as a possible skin and eye irritant. Also it is suspected to contribute to toxic bioaccumulation. Those with sensitive or reactive skin are at risk of an allergic reaction to dimethicone. To top it all off , dimethicone is a non-biodegradable chemical! You really are doing nothing for your skin by wearing products with dimethicone. It is essentially contributing to the aging process. Avoid all dimethicone and similar ingredients like cyclomethicone, dimethiconol, and phenyl trimethicone.
