For adult acne, we usually suggest a combination of our Treatment Line and our Kristina Holey + Marie Veronique collaboration line. If you are experiencing oily/congested acne skin we would suggest starting with the full range of Treatment products including the Treatment Retinol for a full three months. If you are experiencing inflamed, painful cystic acne we would suggest a combination of both lines implementing the Soothing B3 Serum, Pure+E.O. Free Oil Cleanser and for some cases the Intensive Repair Serum for additional exfoliation. Please reach out to our team for individual guidance or refer to our acne section or regimen.
