20% Vitamin C Facial Serum with Niacinamide, Hyaluronic Acid & Vitamin E
I am very pleased with this serum. Makes my skin bright. Reasonably priced and happy it is a Canadian product.

I like the serum itself, which leaves my skin soft and refreshed. The glass eyedropper applicator becomes coated inside. 1/3 of the way through the bottle, the eyedropper is next to unusable, because it doesn't draw the liquid serum inside. I am suggesting that you use a plain cap on the bottle, instead. Using clean fingertips as your serum "applicator" would be much better than the eyedropper. The serum is great, it brightens and smooths my complexion. Thank you!

I love this product and have ordered twice. Effective, easy to use, pleasant texture, absorbs quickly, mild citrus fragrance, affordable. However, though I ordered from the company website it was delivered by Amazon, which I do not patronize, so this will be my last bottle.

What a surprise, I got a bonus product that I wanted, which I did not know you made: the Senzu vitamin C. I spent 15 years as a formulation chemist in pharmaceuticals, so, I was EXTREMELY impressed by the choices of quality ingredients for this formula. I would only ask that you increase the hyaluronic acid to 10%, to make it even more effective. It smooths the skin, no doubt about it. (I am a youthful looking 62). It is a perfect replacement (for me), for Estée Lauder's decades old "Advanced Night Repair" product. Their product formulators were derived from the pharmaceutical business, and your product is oh-so-similar. Time will tell if it is better.😉 I am now a faithful Senzu client. Thank you for prompt delivery of a fresh, quality product, and this freebie! Go CANADA! Keep up the GREAT WORK! Warm regards, Susan Kelemen, from Montreal, Quebec, Canada, eh?
