What Are Silicone Film Formers?

Posted on: October 9, 2025

Silicone film formers function as protective coating agents and are used in various cosmetic and personal care products, serving the purpose of smooth application and durable finish. Film formers are pivotal in enhancing the performance of various products in the skincare, makeup, and haircare industries. Common types include silicones like cyclopentasiloxane and dimethicone, and silicone resins such as trimethylsiloxysilicate, which are used in a wide range of personal care products.

Understanding Silicone Film Formers

A silicone film former, in simple terms, is a synthetic compound which, upon application to skin, hair, or nails, produces a discrete thin, invisible stratum or film, cushioning the surface, providing a polished finish, and prolonging the effects of product application. As a film former, the silicone also delivers a barrier, which protects the skin or hair from external environmental effects, while maintaining a level of porosity for the skin or hair to ‘breathe’ and function normally.

The unique ability to form protective, flexible layers as opposed to traditional ingredients, which act as barriers, is what makes silicone film formers in demand for the cosmetics industry. The invisible, protective, moisture and dirt resistant barriers created by silicone film formers are also unique, as they are not surface coatings.

How Do Silicone Film Formers Work?

Silicone film formers create a layer of silicone upon application. This layer is protective, but the type of protection will depend on the formulation of the product.

In the case of skincare, silicone film formers provide moisturisers with the benefits of water retention. This is because they act as a barrier for water escaping the epidermis, making them important in the formulation of items like moisturisers, sunscreens, and serums.

In the case of makeup, the barrier is associated with a silky, matte finish. This is because makeup is prevented from settling into lines, creases, or over the entirety of the face. The barrier is also associated with extended wear time, as makeup will stay in place and not fade.

In the case of haircare, silicone film formers smooth hair cuticles, which makes hair more manageable and improves the look and feel of the hair. It eliminates frizz while giving a shiny and polished appearance.

Benefits of Silicone Film Formers

The film formers provide long-lasting results because they create a barrier that lasts throughout the day. This makes them popular in cosmetics. They help prevent makeup from fading and skincare from losing effectiveness.

Silicone film formers produce textures that are smooth to the touch and contribute to the ease and pleasantness of product use and application.

In skincare, silicone film formers assist in moisture retention by forming a protective layer that minimises trans-epidermal water loss.

In haircare, silicone film formers eliminate frizz and impart a lustrous, healthy appearance to the hair.

Silicone film formers are a key component in the formulation of waterproof mascaras and eyeliners. They help to lock in makeup and prevent it from smudging, ensuring waterproof makeup remains intact in humid or rainy conditions.

Are Silicone Film Formers Safe for the Skin?

Silicone film formers are largely regarded as safe for all skin types, including sensitive skin. They are non-comedogenic and unlikely to irritate. However, patients with certain allergies or skin sensitivities should conduct a patch test on products containing silicone film formers.

Silicone film formers are essential and multipurpose constituents of cosmetic and personal care products. They extend benefits with high efficacy and durability, improving the overall performance of the products as they form an impermeable protective layer. Silicone film formers are indispensable in the production of value-added products in multiple categories of cosmetics, including skin, decorative, and hair care.

The need for innovation and the growth of the film formers within the aesthetic segment of the personal care industry will continue to reinforce the demand for and utilization of silicone film formers. Awareness of the methods employed in the personal care products and the benefits derived empowers cosmetic users to rationally select products and achieve skin finishing with extended wear.
