Silicone oil, once considered the main culprit for causing acne, is actually an irreplaceable foundational ingredient in high-end sunscreens and long-lasting makeup. When used within compliant amounts, it is not only safe but also enhances the user experience.

Recently, discussions about silicone oils in cosmetics have regained attention. Silicone, once highly criticized, has been considered by many consumers as the 'prime culprit' causing skin allergies and clogged pores. However, professional research shows that silicone oil plays an irreplaceable role in cosmetics. Silicone oil, also known as polysiloxane or silicone, is a high-quality cosmetic ingredient with physiological inertness and excellent chemical stability. It is odorless, non-toxic, and non-irritating to the skin. It has lubricating properties, UV protection, good breathability, can slow the release of fragrances, offers anti-static benefits, and has obvious dust-prevention functions.

Misunderstood Silicone Oil: For a period, many people viewed silicone oil in cosmetics with fear, believing it caused skin allergies and suffocated the skin, making it the main cause of acne. In fact, silicone oil in skincare products is harmless as long as it is used within regulated standards. Experts note that excessive silicone oil can indeed clog pores and create a false smoothness on the skin. Since silicone oil is not water-soluble, if deep cleansing of pores is neglected, it may have some negative effects, but fundamentally, silicone oil does not harm the skin.

Core Role in Sunscreens: Silicone oil is essential for adjusting the feel of skincare products because it is extremely smooth and cannot be easily replaced by other oils. This quality makes it widely used in sunscreens, especially sunscreen products used by everyone during the summer. Take the famous Anessa sunscreen, for example; its formula contains seven to eight types of silicone oils, including silicones for adjusting skin feel, silicone-treated physical sunscreen agents, silicone emulsifiers, film-forming agents, and even the sunscreen agent itself (polysilicone-15), making it a comprehensive collection of silicone oils.

For example, dimethicone and cyclopentasiloxane, the former provides an exceptionally smooth application, while the latter has some volatility and disappears almost completely after use with almost no residue. They both reduce the stickiness of various sunscreen agents and are nearly irreplaceable. Due to the unique bond angles and lengths of silicone molecules, oxygen and water vapor can pass through them, allowing sweat on the skin to evaporate freely without a feeling of heat or stuffiness, which is exactly the characteristic needed in sunscreen.

Indispensable in Makeup: In makeup products, silicone oils also play a key role. Besides texture, resistance to water, sweat, and wear is critical. Silicone oils are essential for water-resistant film formation. Especially silicone-modified film-forming agents, which help makeup last longer while creating matte or glossy effects. For instance, some lipsticks that claim to be non-transfer achieve excellent anti-smudging properties by adding a specific proportion of silicone resin film-forming agents.

Take Dior's spray foundation as an example: it is a silicone-based formula containing octyl dimethicone ethylhexyl glucoside, a combination of silicone oil and natural glycosides, which improves moisture, skin affinity, gentleness, and even offers some natural biodegradability.
