Bought this item without much of an expectation, however this was a surprise find. I have been using multiple products to brighten my skin as I’ve found that my complexion has been quite dull lately. Been using vitamin c products previously which may have caused a little more dryness. After using this ampoule with set, to my surprise, after around half a month, I have noticed a notable difference to my whole complexion. It is brighter and making it look healthier overall. I am very happy with this purchase and will definitely be repurchasing as it gives me a healthy glow. This ampoule is thick so I only use 3 drops every time which will be enough to cover my entire face. It absorbs well into my skin (I do have dry skin) and cannot feel it being sticky after my final step of moisturizer. I feel using the same line has boosted the effects of the brightness in my complexion. Would love to try out the moisturizing cream next time to see if it will boost even more of an effect.
