A baby's skin is 5 times thinner than an adult's and does not function fully as a protective layer, which is why it is important to care for its protection with products that do not cause irritation, such as Baby Planet, which are hypoallergenic, dermatologically tested, and specially designed for the sensitive skin of babies. They do not contain dyes and other synthetic chemicals such as EDTA, CMI/MI, and nitro–musks which could irritate the skin or be harmful to health.
