The key is consistency
This has been wonderful for my skin! Most products that are aiming to tackle dark spots contain vitamin C, which is a great ingredient to tackle things like hyperpigmentation, however my skin absolutely can NOT handle it in any form. Finding a dark spot product without vitamin C that works had been a bit of a challenge, but this is it! I love this product! Niacinamide, tranexamic acid, alpha-arbutin, and kojic acid are great alternatives to vitamin C for fighting dark spots. This product has a very creamy and moisturizing formula too, which my dry skin loves. However, it’s important to remember to be patient and be consistent because dark spots take time to tackle. This won’t work overnight. Give it time and don’t forget things like sunscreen (UV rays make dark spots worse). If you are dealing with dark spots, I highly recommend adding this into your routine.
