Is it normal for a 21 year old to have nasolabial folds?

The appearance of nasolabial folds is not always age related. Nasolabial folds can develop due to hereditary issues as well, so it is possible for children to even have nasolabial folds.

Yes it is! In fact you will notice that children with full cheeks have natural grooves between their cheeks and lips. These cheek-lip grooves are normal, and they may become deeper and wrinkled with age - that when to treat. Not now. Hope this helps. Dr Joseph
