    My HL vitamin C serum
    December 28, 2019
    It's one of the best Vitamin C serums I've used so far. It helped in fading my acne scars and my skin become even out. I stated seeing visible results after 2 weeks of regular use. I keep it in refrigerator to avoid rapid oxidation.

    final update😍

    Use my code for discount CK8KP4 ❤️

    Since I have been using this product for quite some time now, mine didn't oxidize in about 2 months. Not even turned yellow, that's because I followed the instructions carefully, i refrigerated the product before opening, and since then it's in the refrigerator. Whenever i use i make sure that i don't keep it open for long and put it back in fridge immediately. So apparently unlike other's mine didn't give me hard time. I'm sharing this to make sure that nobody has to complain about the oxidizing factor. Also don't keep the bottle in the bathroom cabinet or anywhere in dark, refrigerator is the only and sole option for this serum...
    As I have shared that this works best on my skin, so I also noticed that too much use of products (retinols, niacinamides etc) has probably made my skin bit sensitive so now it tingles for sometime but that's ok.. It works even better when paired up with vitamin E moisturizer. Ta Da, i hope it was helpful and you guys would love the product too.
    Would purchase again and again

    this serum has lightened my skin like a miracle, I have never loved any product to such an extent. I think this is a must have for the rest of my life. Do try using it along with niacinamide and voila you'd definitely love it. Helps in reducing acne scars, hyper pigmentation, sun spots, aging spots and large pores. I have also noticed less black and white heads on my nose after using this so yeah it did suit me really well. People around me also complemented how my skin looks even and brighter. So happy 😊
    Best Serum
    November 21, 2019
    I am using this serum and in no time it has become my holy grail product, I absolutely love how it has brightened up my skin. I have ordered one more.
    I'm also using niacinamide in my routine so that definitely speeds up the brightening process. Anyone having dull looking and blemished skin must try this.

    Spectacular product for my skin
    March 3, 2020
    This serum has cleared my skin tone and in a short time it has become one of my favorite sera. I love it, I love this product because it is absorbed in my skin and gives it an immediate shine. A recommendation so that it does not rust early, please after opening and use it to store it in the refrigerator. I would buy it again without hesitation.

    My HG
    December 12, 2019
    This vitamin C is diluted in a water base so its tends to oxide easily if you don't keep it in your refrigerator. So leaving aside the disadvantage of its rapid oxidation, in general I liked the product. It has a sticky texture that can not please many people and, it really has a citrus scent but I can perceive a subtle aroma of alcohol that is the third ingredient. The concentration of vitamin C, which in this case is ascorbic acid, is 20% so if you're first time using acids you have to include it slowly in the facial routine, but always remember to do the patch test to rule out any reaction. In my case, despite I'm having been using acids for more than two years, the skin always turns red, so I do not use it daily in the first two weeks, until my skin feels comfortable to use it daily. It is also important that after 15-20 minutes (the time you need for the serum to be absorbed by the skin) the other products that you apply on the skin must be moisturizing.
    I've noticed some improvements on my skin like the reduction of my cystic pimples during my period, also my skin looks brighter and I feel it smoother. Besides the wrinkle around my mouth (nasolabial fold) is less deep and I really happy with this result. I use it in the morning because the vitamin c is antioxidant that helps us to keep the skin protected from the UV.

    This vitamin c serum is sticky and has a citrusy scent. It didn't do much for my skin though.

    My first ever serum
    November 19, 2019
    I only got into skincare routine after discovering YesStyle.com. So to start my routine I selected this Vitamin C serum because the price was very reasonable and I didn’t want to invest a lot into a new product. Also the reviews all over the Internet were very positive. I have been using it for almost 3 weeks now and I can say that so far so good. It hasn’t done miracles and one shouldn’t expect miracles either. One should give some time for a product to work. However this product is gentle on my skin and I feel that my skin has started to look healthier. I think it is a good serum to start with, even though it has high % of Vitamin C, so may be people with sensitive skin should be cautious. I am hoping to see significant/noticeable difference after using it for some time. Perhaps I will update about my skin condion in a couple of months time.

    Perfect for my skin
    January 4, 2019
    This vitamin c serum really helps to lighten my hyperpigmentation. I have combination skin that is prone to breakouts, but you wouldn’t be able tell because this has really helped to get rid of any scarring.

    this is a game changer in skin care routine. Might sting a bit after first use but that goes away fast. Plumps my face but be consistent and patient to see the results
