Ingredients for Clear, Long-Lasting Acne Scar Primer

Ingredients for Acne Scar Primer

For creating a clear, long-lasting primer that fills pitted acne scars without leaving a white cast, the main ingredients typically used are silicones, especially silicone elastomers dispersed in silicone fluids. This combination helps create a smooth film that effectively blurs and fills pores and acne scars.

Recommended ingredients include:

• Silicone Gel (Dimethicone Crosspolymer in Dimethicone): This is the primary ingredient for filling and blurring acne scars and pores, making the skin look smoother. It is a slightly opaque gel, but when applied to the skin in an appropriate amount, it provides a translucent feel and helps to conceal without leaving a white cast, while also giving a soft, smooth, and matte finish.

  • Example products: Silicone Gel (Medium Matte, Dimethicone Base) or Silicone Gel (High Matte, Dimethicone Base)

• Dimethicone (Silicone Fluid): Used as a base or solvent for the Silicone Gel, it helps the primer spread more easily and gives the skin a soft, smooth feel. You can choose the desired viscosity; lower viscosity will feel lighter and evaporate slightly faster.

  • Example products: Dimethicone (Light/50, Low-Odor) or Dimethicone (Ultra Light/1.5, Low-Odor)

• Trifluoropropyl Dimethicone/Trifluoropropyl Divinyldimethicone Crosspolymer: This is a fluorosilicone that enhances water and oil resistance, making the primer last longer. It is suitable for formulas requiring extra durability. However, this ingredient may require emulsification as it does not directly dissolve in oil or silicone when mixed into a formula.

Formulation Approach:

Generally, this type of primer uses Silicone Gel as the main component to create the film that provides the filling effect, and liquid Dimethicone as a dispersant and to adjust the texture and viscosity of the product, making it suitable for spot application.
