As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephen writes on reddit"sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution". It’s used mainly for its soothing and anti-inflammatory properties, but according to manufacturer info, it’s also sebum regulating so it's a perfect ingredient for problem skin products. Using it for a few weeks, I feel like my skin has become a little bit brighter and evenly toned than it did before. However, I do not really see that much change when it comes to my sun spot, maybe just slightly faded. I think that if I keep using this for months, I will definitely see a change to my skin tone if I see a slight but obvious difference within 2 weeks. It still questions me why the main ingredient Tranexamic Acid, is completely removed from the new formulation as it was the main ingredient Hada Labo marketed for the old formulation. Does it have to do with complications in other countries? I came across an article some time ago that this lotion (rich) is banned from the Philippines due to unsafe ingredients. I just skimmed through the article so I can't really remember. It's been ages since I last used this lotion so I couldn't care to look more into it,

It's a cheap, effective and well-tolerated ingredient to make sure the cosmetic formula does not go wrong too soon. Do not be alarmed, the word, “whitening” is not what you think it is . In Japan and in various Asian countries, you may come across beauty products that contain the word “whitening.” However, the majority of the time, the idea of “whitening” is equivalent to the idea of “brightening” or evening the skin. It’s the - sodium form - cousin of the famous NMF, hyaluronic acid(HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here. The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water. It's enriched with antioxidants and other nutrients that help even out skin tone and fight the signs of ageing. Plus, it's incredibly moisturising, leaving your skin feeling soft and smooth.

MAP does solve the stability problem: it's stable up to pH 7, so far so good. What is not so good is that, as the great review study about vitamin C derivatives in the Journal of Cosmetic Dermatology writes, MAP is "at very best, poorly absorbed in comparison to AA." Moreover, derivativesnot only have to be absorbed into the skin, they also have to be converted into pure AA. The good news is that in-vitro data shows that MAP does convert, but the bad news is we do not really know if the same is true on real, living human skin. Even if it does, we don't know how good the conversion rate is (but to be fair the same is true for all other derivatives).Other ingredients: Vitamin C Mg phosphate, vitamin E, hydrolyzed hyaluronic acid (nano hyaluronic acid), hyaluronic acid Na-2, DPG, BG, diglycerin, concentrated glycerin, hydroxylated soybean phospholipid, PEG- 8, PEG(30), POE(20) lauric acid sorbitan, VP/styrene copolymer emulsion, citric acid anhydride, paraben Regarding the three magic abilities of pure vitamin C(antioxidant, collagen booster, skin brightener), there is no published data about MAP's antioxidant or photoprotection capabilities. We have better news about the other two things: in-vitro data shows that MAP can boost collagen synthesis similar to AA (though in thecase of AA it's proven in-vivo) and even better, MAP is proven to work as a skin brightener in-vivo (on real people).
