Vitamin C Suspension 30%

In my atm routine i use cetaphil cleanser -> TO niacinamide - caffeine eye cream - moisturizer every day. In the evening I use a oat cleanser befor the cetaphil cleanser. I want to implement this product in to my routine, as well as retinol either 0.5% or 1%. How should I do this? Can I continue using niacinimade every day with retinol some nights in the week and this produvt a couple days in the week? Or is niacinimade not compatible with any of the products?

I've been using this serum for a few days and I'm not sure about the consistency and the feeling of the product. I'm not talking about the gritty sensation or the quite liquid consistency that sometimes makes it difficult to apply, I think the main problem for me is the feeling that it leaves on my skin. I can feel my skin super oily and "heavy" even with using just a few drops of product... I wanted to start using it in the morning but this makes it impossible for me to keep it on my face for the whole day, so I will try to finish the tube by applying the serum at night instead. Good thing i…

I’ve given this product 3 stars simply because of the gritty texture, it felt very uncomfortable on my face. I’m not sure if the grit is an added exfoliating effect but it made my face burn a little all day. I might use it on my hands but I don’t think I’ll use it on my face again

This product is definitely a hidden gem. It takes some manipulation to get the application just right, but the results are unmistakable. I mix it with a few drops of Resveratrol + Ferulic and apply to slightly damp skin. Super plumping and brightening! The only problem is my fungal acne, and this contains some fatty esters that aggravate it. I guess you could say this is oil free in some sense, but the second ingredient being squalane, and the esters don't quite meet my definition. Still a great product though!!

I love it. I read that it was gritty so this was expected and I understand it as I make my own niacinimide cream from powder. Sometimes this is the most effective method and in this case I understand why. The tingling was mild and expected due to the high concentration, and the hyaluronic acid worked to keep my skin moist. And what a fabulous value! Will definitely buy again.

I didn't mind the feeling of this product. It went on a little gritty and left my face covered with a sheen for a good 40 minutes while it absorbed in, which made it hard to layer on other treatments and products. It might be a combo of using too many exfoliants, but after two weeks of using this I saw many sebaceous filament appear along my chin, forehead, and my nose -- areas where these were not prominent nor visible previously. I stopped using this product but continued with the rest of my regimen and the filaments have reduced in appearance after 4 days. I did notic…

For effectiveness I would give this a 9. I noticed a big difference in my skin within a week of starting use. That being said as far as texture goes I would give this a 4 or 5. I do get a little bit of tingling and there is a grittiness to it but that doesn't really bother me as much as the oily feeling it leaves on my face that takes at least an hour to go away. I make sure to use no more than a pea sized amount as recommended and also tried mixing it with the moisturizing factors +HA but nothing helps. I prefer to use my vitamin C in the morning and having to wait an hour before it has absor…

I see some minor difference after use, however, it does not absorb well.. I find that 30 minutes after applying it is still not absorbed and rather oily and gritty on my face. Putting make up over it is an absolute no no.. I think if it died with the matte finish of the azelaic acid suspension, I would be inlove
