I love this product so so much i struggled with hyperpigmentation on my chin and i was so insecure but now its almost gone and i have only used it for a week. It made so much difference and it also helped some of my redness from a recent breakout from waxing my face. I had previously used a kojic acid soap bar however it didnt really help. It looks like i have batley used the bottle it has so much product and such good effectivness. I will definitely purchase other items from this brand after seeing how good this ampuole is. The ampuole didnt sting on my face or make it feel wierd and uncomfertable it felt like nothing however ot does feel abit sticky after you put it on. It also doesnt have any scent.I will update when all my hyperpigmentation has gone.

After using this for a while I got to half of the bottle, so now I have more optionsThis is lightweight serum. Ag the same time it's refreshing, but messes up my routine.When I apoly it after vit C in ghe morning it makes my souper smooth Benton's Vit. C serrum to kind of like... get liquidified, which looses mg time and product.It also something feels unpleasant upon application, as before or after Pyunkang Yul calming ampule from the green line. PJY ampoule by itself is so pleasant, but if i pair it with this product it gets unpleasant and diesnt sink in, which is crucial if you hurry in the morning.I can make this ampoule work in the evening, but after I use retinoid I have to wait a lot. or otherwise it makes my retinoid "liquidify" which is quite weird. ... MoreAfter using this for a while I got to half of the bottle, so now I have more optionsThis is lightweight serum.

Maybe it's the gel consistency. But it didn't happen before with mh othed brightening ampoule.I didn't notice much change in the brightness of my sunspots, which i successfully treated with TXA and lotus ampoule. But I was shocked last Sunday to find my sunspot was more prominent. asi I switched the Skin1004 brightening ampoule to Nineless TXA ampoule and got results after just 2 applications.So thus goes in the drawer for when I stop going to the beach, meaning till autumn.

This product comes in at 100ml and is great value for money. I've been using it as my A.M. serum. I'm onto my second bottle now, but the first one lasted 10 months. I have a medium skin tone and have very stubborn pigmentation concerns and some PIE. This serum, for me, was very soothing, but not the most brightening despite the 4% niacinamide and 2% tranexamic acid. The newer Haruharu Wonder TXA serum also combines centella, niacinamide and tranexamic acid, however, with a higher concentration of tranexamic acid at 4%. I've purchased it and hope that it will be a better fit for me. This Skin1004 ampoule might be worth checking out for anyone with mild pigmentation concerns, as it comes in a generous-sized bottle.
