FAQ

1. Is dimethicone safe during pregnancy?

Yes, dimethicone is considered safe to use during pregnancy.

2. Is dimethicone good for hair?

Yes, dimethicone is widely used in haircare for its many benefits. It tames frizz and static, making hair smoother and more manageable. It also smooths the cuticle, which adds shine and makes hair easier to comb. On top of that, dimethicone creates a protective layer against heat and environmental damage.

3. Does dimethicone cause acne?

This molecule itself doesn't cause acne. Dimethicone in skincare is considered a non-comedogenic ingredient, meaning dimethicone doesn't clog pores. The myth that it "seals" pores comes from the fact that it forms a protective film on the skin. However, this film is semi-permeable, not airtight, and doesn't interfere with the skin's normal functioning.
