    • Serum Description
Size: 1 Fl Oz (Pack of 1)
This serum has helped my acne so much ! It’s clear and doesn’t have a scent. The packaging is efficient and the dropper works very well. This serum didn’t irritate my sensitive skin which is really great ! This serum has helped me prevent so many breakouts and leaves my skin glowy and plump. Amazing for acne prone skin ! This product isn’t super expensive but it works great! The consistency is non sticky but not super thin. The residue on your fingers can be applied on your neck or chest. It doesn’t dry my skin and still gets rid of acne! I would recommend this for teens or people that struggle with acne. This serum is so worth it ! ... show more

    • Reduces Redness and Tightens Pores
Size: 1 Fl Oz (Pack of 1)
I used to have really nice skin, but ever since I started the ketovore diet 2 years ago, my face has become somewhat porous and ruddy. I don’t have acne, but I have been hating my skin texture and tone. A little research suggested that it was due to the increased fats my diet, which are causing my sebaceous glands to secrete more sebum. It suggested that I use niacinamide powder (Vitamin B3) mixed with zinc PCA in a 10% to 1% ratio by weight in distilled water to pat on my face, stating that it would calm my skin down and help with the appearance of large pores and uneven tone. Fortunately, I was able to skip breaking out the scales and doing science in my kitchen, since I found this inexpensive serum online. It is close enough in formulation to what was suggested in my research. The serum is light, non-greasy, and it glides smoothly over my skin. The size of the tiny bottle was a little disappointing, but the product is quite inexpensive and I found that a little goes a long way. The serum doesn’t take long to dry and it doesn’t feel sticky afterwards. I have used it for about a week now. It is working. My pores aren’t perfect yet, but they do look noticeably smaller. My skin seems to have calmed down a bit. It isn't quite as ruddy. I don’t find this serum particularly moisturizing, however. It seems to make my skin feel tight. Nevertheless, I’m pleased with the results. ... show more

    • Lightweight Formula With a Simple Routine
Size: 1 Fl Oz (Pack of 1)
The lightweight, water-based formula is one of the things that makes this serum easy to work into a skincare routine. With 10% niacinamide and 1% Zinc PCA, it focuses on several everyday skin concerns without turning the routine into a complicated process. I also appreciate that the product information is clear about what the serum can and cannot do. It specifically explains that it isn’t an acne treatment, while noting that it can be used alongside acne treatments. The directions are straightforward as well, with just a few drops recommended in the morning and evening. The focus on hydration, radiance, smoother-looking skin, and supporting the skin barrier makes this feel like a practical addition for someone looking to improve the overall appearance of their skin rather than expecting an overnight transformation. I also liked that the clinical information gives a clearer idea of the timeframe for the reported results, including barrier hydration and smoother-looking skin. A simple formula, clear directions, and an easy-to-understand purpose make this a convenient serum to add to a regular skincare routine. ... show more

    • Lovely product
Size: 1 Fl Oz (Pack of 1)
I have very acne prone skin and oily skin. To be honest in the beggining it did sting but after a while the stinging went away after 2 weeks. I applied twice a day morning and night!! My skin did look overall more healthier and gave me a nice glow which i like and my skin started clearing up after a month! I use it with my tretinion but currently im only using it in the morning so my skin isn't irritated later on. I would say this is something im going to be investing more into i already went through 5 bottles!! But keep this in mind, you don't need this. lots of hydrating or skin repair serums and creams already have niacinamide! Dont want everyone to spend there money on a product that contains something that they already have( more common than you think)●0●!!🗣🤍. So other than that it really is there for more additional help more than anything. But if u feel like u can benefit from it go right ahead 🫶 ... show more

    • Not great, but not bad.
Size: 1 Fl Oz (Pack of 1)
I bought this as a cheaper alternative to Byomas clarifying serum. It works enough. It keeps my complexion relatively clear but doesn’t completely get rid of the blemishes or texture whereas the byoma does. The current effectiveness could have something to do with hormonal and environmental factors as well. It is a slight bit drying on my skin, I recommend only using it twice a day while your skin is still adjusting, if it starts drying out then use it once a day. The product first smells a bit weird but it doesn’t leave the smell on your skin. I’m still unsure if I will continue to repurchase this product, but after a week I am overall satisfied. ... show more

    • 10/10 that's a definite recommendation!
Size: 1 Fl Oz (Pack of 1)
I love this serum so much. I have scaring on my chest from getting shingles 5 times in my life time...I know im only 40 so that's strange but I have a lot of discoloration and using this has made a definite improvement in my coloration and uneven tones. I use it every day and it feels so smooth going on, absorbes easily, doesn't pill up. Bottle is a goid size, a little bit goes a long way. Definitely helps with hydration and I do notice a glow to my face after using for a while. I've been using it for 3 months and everyone comments on my skin. Definitely recommend because you certainly can not beat this price! ... show more
