Apply to damp skin. Two or three drops is enough for the whole face, and the serum spreads further and sinks in faster if your skin is still damp from cleansing or toning. Press it in with your fingertips rather than rubbing. Always follow with a moisturiser. This is a hydrating serum, not a moisturiser, so it needs sealing in. The order that works best is cleanse, tone, peptide serum, eye cream, moisturiser, then SPF in the morning or a face oil at night. Don't stop at the jawline. Take it down the neck and chest, where people tend to notice the biggest difference.
