Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [International Journal of Toxicology, 2019](https://pubmed.ncbi.nlm.nih.gov/31840548/)

### Where does this serum go in a skincare routine for oily skin?

This serum goes in the evening routine after cleansing and before moisturizing, which keeps the routine simple and safe around sun exposure. Using it at night helps manage oily shine by delivering lightweight hydration and keeping your skin smooth.
Sources: [International Journal of Molecular Sciences, 2025](https://pubmed.ncbi.nlm.nih.gov/39940752/)

### Can this serum clog pores, cause breakouts or purging for oily skin?

This serum is unlikely to cause breakouts or clog pores on oily skin because it avoids harsh ingredients and uses light silicones that keep things smooth without feeling heavy. It helps keep your skin balanced and hydrated while maintaining a safe profile.
Sources: [International Journal of Molecular Sciences, 2025](https://pubmed.ncbi.nlm.nih.gov/39940752/)

### Can I use this serum around the eyes or on my body?

This serum is a great fit because dimethicone and polysilicone-11 keep oily skin soft without feeling heavy, while polyglutamic acid holds moisture well. Because the skin around the eyes is very thin, it requires gentle formulas like this one that deliver lightweight hydration without causing irritation.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [International Journal of Molecular Sciences, 2025](https://pubmed.ncbi.nlm.nih.gov/39940752/)
