This solution was very easy to apply thanks to the dropper bottle. It lets you be precise with how much you need and I used a drop for my forehead and a drop for my chin. With the 30ml bottle, this would last me a long time. The consistency is watery and it spreads well and absorbs quickly.
Unfortunately, I haven't seen any difference in my dark spots yet after using this solution for 3 weeks. I am going to continue using it as I think it may need more time to show results, but at the moment I could not recommend this yet. Unless I see good results with long term use, I wouldn't consider replacing it as it is a pricey product.
Quite expensive and not effective for me. I gave it a really good try but didn't see any difference at all with pigmentation areas that were a problem for me. I'm getting much better results from microdermabrasion and dermarolling.
