What is the SkinMedica® GRASS Regimen?

The science that makes beauty a reality
SkinMedica® has designed the GRASS Regimen to help take the guesswork out of choosing products for your skin care needs. Each letter (G, R, A, S and S) represents a product category. Combine products from these categories to create your personal regimen. It’s that simple.
