Cleansing gently without irritating the skin!!!!

The product I use is Bioderma Cleansing Water. I've been using it for over 10 years, and I think thanks to this, my skin hasn't been damaged even when I wear makeup because it cleanses so well. First of all, it's 500ml, affordable, and lasts for three months, so it offers great value for money. If I cleanse with about two cotton pads and then wash with a gentle cleansing foam, I can wash my skin without feeling too heavy or too light. :) There must be a reason why I've stuck with this product for over 10 years, right?
