@duplikabeauty: Set it all out before you begin. A little look at my counter on Cool & Plump day. The shelf, the guide, the blend, the pH check. The rest is in the guide. Cool & Plump is a free, complete guide to a six-ingredient hyaluronic serum you make at home. Properly preserved, about $2 a batch. Grab it free at the link in bio. #diyskincare #skincareformulation #homemadeskincare #cleanbeauty #hyaluronicacid #serum #formulator #skincarecommunity #duplikabeauty
