Paula's ChoiceBOOST C15 Super Booster, 15% Vitamin C Serum for Face, Face Serum with Vitamin E & Ferulic Acid for Discoloration & Glow, Fragrance-Free, 0.67 Fl Oz

Just received this item and have been using it for a week now. I’ve decided to invest more time and energy into my skin care routine since I am getting older. Within one week, I’ve noticed the difference in my skin softness and smoothness. Also, my dark spots are getting less pigmented. Having a routine helps to support the full effects of this serum. The effectiveness of this product, following a skin care routine, is improving how I look and feel. Using the serum enhances the products I use afterwards. Moisturizing adds to the effectiveness of my total skin care routine. The investment is worth having a brighter, clearer, and smooth complexion.

I am truly impressed with these serums. Since I started using them, I've noticed my skin is much more hydrated, soft, and has a healthy glow. But what I liked the most is how they've helped fade some sun spots I had. They absorb quickly and don't feel heavy. Without a doubt, a very good product that I will buy again.

The dropper came broke which sucks. Product is good tho!

Definitely recommend! I've been using this product for maybe 2 years and it's done wonders for my skin. I had a different vitamin C serum before this and this one is by far my favorite. (After adding a gentle retinol into the mix it's even better.) The one thing I will say is that it's basically like water so I usually hold a hand up to my face and rub/dab it in as I go so it doesn't run all down my face. It doesn't bother me though since it actually makes it easier to apply all over the face with very few drops. I would say a bottle lasts me anywhere between 2-3 months.I see some reviews talk about issues with packaging and spills but I've personally never had an issue with any of that so, it might depend on location or how far the package is being sent. And for anyone concerned about the product being different colors when you order a new replacement, that's just how this product works! Visit Paula's Choice website or google about the product. There's actually a variation of different colors this product can be and still be safe to use. Vitamin C is finicky like that.Another warning is be careful what else you mix this with and how you layer it with other products. Looking at all the reviews I am curious how many novice skincare folks are buying this product not realizing that vitamin C is an acid. If you don't know what you're doing then you might end up seriously damaging your skin's acid mantle which can causing irritation, burning and/or breakouts. Most of what I'm seeing in the photos looks like that's what happened too so, proceed with caution if you aren't familiar with how to mix skincare products or have especially sensitive skin. And if you use physical exfoliants (which, really no one should be but that's a separate topic) then definitely do not apply this for at least 24 hours. (Again, it's an acid. The pH is 3.1–3.5 according to their website and most retinol's are around 5-6 pH levels.)♡

This product burned my face and left it red and blistered! I used two drops one day and did fine so the next day I used one dropperful. Both times I mixed it with squalene oil. The second day was a disaster. Within an hour I could feel my face starting to get warm so I tried washing my face with gentle Cerave cleanser then coated my face with aloe vera and squalene, but it was too late. By the afternoon my face was red and little blisters had started to form. My husband noticed and asked what I had done to my face. At night I washed with Cerave again, used my squalene and aloe vera, then covered that with cicaplast baume. Still red and blistered this morning, but fingers crossed, it seems to be improving today. I will obviously not be using this serum again and would not recommend it to anyone. It's expensive and from a big name company so I expected much better from this product.

Not sure if it worked at first because I have very sensitive skin, but I was wrong. I enjoy it every day now.

Was ok. Not great changes but some small wrinkle changes. Cost ok

This vitamin C serum is very nourishing and goes on very smoothly without separating your makeup. Highly recommended for skin with fine lines.
