My teen daughter is a competitive swimmer (nearly) year round. She shares a tendency toward acne from her dad's family and has really been struggling the past year. She has known reactions to certain chemicals in beauty/daily hygiene products, which led us to wonder if one of the pool chemicals was also becoming an issue. After a lot of research we decided to give this brand a try. She has the inflammation and acne on her face, but is always dry (a.k.a. swimmer skin) and was hesitant to completely change her regimen. We decided to have her use the dermasport system every evening and continue with her plant-based, acne fighting system in the morning. We noticed a difference after 2 days of use - what a change! Inflammation is down and she has less overall redness and roughness on her face and shoulders. Acne is slowing improving after a weeks use. Hopefully this will continue to be a great solution!!
