I was very excited to use this product and I was ready to wait a month or two for results but in one week of using this alongside the moisturizer most of my stubborn dark spots and acne scars started fading, ofc it’s not all gone but it’s a lot of progress for only using it a week. Although it did irritate my skin a bit at the start so if you have sensitive skin, use a tiny bit first and then progressively apply more otherwise you will destroy your skin barrier!
