Hello, my son is 3.5 years old and has been having skin problems since...

First and foremost, it is important to consult a dermatologist or pediatrician for specific recommendations and treatment. They will be able to select suitable products and procedures for caring for your son's skin. Some general recommendations for skin care in the case of ichthyosis include: 1. Using moisturizers and gentle cleansing agents for the skin. 2. Avoiding prolonged hot baths and showers, as this can worsen skin dryness. 3. Applying moisturizing creams or oils to the skin after bathing. 4. Avoiding the use of harsh skin care products, such as soap or scrubs. 5. Wearing soft clothing made from natural materials to avoid skin irritation. It is also important to monitor your child's diet, including foods rich in vitamins and nutrients that can help improve the condition of the skin. However, again, it is best to get a consultation from a specialist who can provide individual recommendations and treatment for your son.
