Fixderma Shadow SPF 30+ Gel can generally be used in children, especially older kids with normal, non-sensitive skin. However, for infants and very young children, mineral-based sunscreens or physical protection such as shade and protective clothing are usually preferred. As children have more delicate skin, a patch test is recommended before regular use to check for any irritation or allergy. If your child has sensitive skin or any skin condition, it is best to consult a paediatrician or dermatologist before regular use.
