The serum kit is amazing and I love the new size! I initially started using Almond clear for butt acne and it cleared it right up after a month. With the kit I use it all over my body especially for dark spots and dry skin. Here’s pics of what my Apple Watch did on my wrist so I used Level 1 serum and it cleared it within 3 days. Amazing results, please note for tough marks like hyperpigmentation it does take time for you to see results, be persistent and diligent! It will work.
