For children (age 5 and up), glycolic acid can be used carefully but it is not risk-free. The main risks are skin irritation, greater skin absorption of other ingredients, and increased sun sensitivity. Long-term cancer or reproductive risks are reported as low by safety reviews, but official advice limits how it can be used.
If you choose a product with glycolic acid for a child: pick low-strength or rinse-off products made for sensitive skin or children; do a small patch test on the arm and wait 24 hours before using more widely; avoid putting it near the eyes, mouth, or on broken skin; do not use professional peels or high-strength products at home; always apply sunscreen on treated skin during the day; stop use if you see redness, stinging, or peeling and talk to your pediatrician or dermatologist.
Watch for skin irritation and stinging (this is the main safety concern according to health and regulatory reviews such as Health Canada and industry safety panels). Also be aware that this ingredient can increase how much other substances penetrate the skin and can increase sun sensitivity (noted by industry safety reviews and chemical safety agencies). It is restricted or limited in some countries, so avoid strong or professional-strength formulations for children and follow product directions closely.
