Two words describe Anua's Heartleaf 80% Ampoule in our opinion: Game. Changer. If you have sensitive skin and subclinical acne, this nourishing serum is for you. The 80% Houttuynia Cordata extract along with Chinese Senna and panthenol in this simple formula can do an incredible job at reducing redness and those tiny, annoying zit bumps on skin. For us, it improved texture and improved overall skin tone within a week! It also feels very hydrating, so we think dehydrated skin would benefit from this ampoule as well.
