Treatment serums and ampoules sit together here: KRX Mela Defense and Face Lift Intensive Firming serums, the Salmon DNA Meso Booster Ampoule, Inflacure Healing Active and the Dermathod Priming Peel Pads that prepare skin before actives go on.

Many suit microneedling and infusion work as well as topical application. Check each listing for whether a product is rated for needling or for surface use only.
