Can I use the HydroPeptide® collection with other skin care products?
The HydroPeptide® collection has been designed to meet all your anti-aging needs so if possible use products from the line. If you choose to incorporate other products, we suggest testing any combination of skin care products on the inside of your forearm before applying it to your face to check for irritation. The basic rule of thumb, is to apply all your serums first (to clean skin) and then your creams. For prescription skin-care products, consult your physician.
