No. You can wash HappySkin using regular detergent along with your other laundry as the base layers provide protection against skin irritants often found in washing detergents.. So it’s hassle-free. Just make sure to wash them at 40°C or less in a whites only wash load. Plus, our base layers will continue to perform for up to 40 washes. So you save time and money without compromising your child’s comfort.
