Various forms of silicone are used in cosmetics, especially leave-on skin care products and various forms of hair care products. Common forms of silicone may be cyclopentasiloxane and cyclohexasiloxane. Other forms include various types of dimethicone and phenyl trimethicone.
What is silicone?
Silicone is a substance derived from silica (sand is silica). Silicone has unique flow characteristics that make it extremely slippery, and in various forms, it feels like silk on the skin, imparts emollient properties to the skin, and even when the skin becomes wet A water binder that holds well. In other forms, it is also widely used for wound healing and improving the appearance of scars.
Silicone and acne
The claim that no form of silicone will cause or exacerbate acne has not been confirmed in published studies, and there have been no reports of silicone irritating or "suffocating" the skin. Almost all of these claims are based on myth or anecdotal evidence, which is not the best way to determine the safety or efficacy of any cosmetic ingredient.
Can silicone fill the skin?
How do we know that silicone will not suffocate the skin? Due to their molecular characteristics, they have both porosity and air resistance. Think about the silicones in skin care formulas, such as the cover of tea bags. When you immerse a tea bag in water, the tea and all its antioxidant properties are released. Silicone remains on the surface of your skin, while other ingredients are mixed with "steep" oil. All ingredients must be suspended in some basic formula. Some of these ingredients remain on the surface and some are absorbed. Either way, the "activity" will pass. Consider how many kinds of topical medicines are suspended in petroleum jelly or mineral oil. These active ingredients can definitely pass. Petroleum jelly is much more effective than silicone in preventing water loss. Silicones have been used in combustion devices for many years due to their unique healing, protection and breathability properties.
Moreover, the molecular structure of commonly used silicones makes them impossible to suffocate the skin. The unique molecular structure of silicones (larger molecules, with a wider gap between each molecule) makes them a barrier to breathability, and it also explains why silicones rarely provide protection against water loss, but they rarely The reason for feeling heavy or blocked.
Has silicone blocked the pores?
Interestingly, silicone has been shown to help counteract the drying and flaking caused by common anti-acne active ingredients (such as benzoyl peroxide) and topical antibiotics. (Furthermore, silicone fillers are sometimes used to improve the appearance of acne scars. If silicone is an ingredient that clogs pores, this will certainly not be the case.) Perhaps, the most convincing reason is that silicone does not clog pores And cause acne (or blackheads) because from a chemical point of view, most silicones are volatile substances. This means that their initial sticky (thick) texture quickly evaporates and does not penetrate the walls of the holes that form acne. Instead, they help ensure that other ingredients are used evenly and leave a silky, almost imperceptible feeling, which significantly improves the texture and appearance of the skin. You can think of it as a breathable barrier that protects the skin and is hardly felt.
