Paula’s Choice C15 Vitamin C Super Booster

[I received this product in exchange for my honest review] For starters, the packaging is simple and it has the instructions. For the product itself the formula has a nice lightweight texture, in a bottle that has a built-in dropper— when you unscrew the cap, the dropper is attached and ready to use for easy application. The product does absorb quickly, doesn’t leave my skin feeling sticky or heavy. While the product does have a strange scent due to its active ingredients, however the scent goes away after application. Even though I have sensitive skin I did not experience any negative reaction or irritations when using the product. I did notice some slight changes in the brightness of my skin, enough for me to purchase this? I’m not sure.

Great if you can use it quick enough

I love this one at first started out, but it started to smell horribly and I’m pretty sure an oxidized. I think this is a good dupe for the SkinCeuticals one at a much better price point but you have to use it up quickly.

[I received this product in exchange for my honest review] I can confidently say that This is the best Vitamin C serum i have ever tried. This combination makes for such a powerful formula. It applies smoothly, absorbs quickly and don’t leave my skin feeling heavy or sticky. With consistent use, my skin looks brighter, more even and has a healthy radiant glow.

Nope

Not worth the insane price increase. It was a good product when it was 35 percent less. That increase is egregious.

Very greasy!

After trying this product for a while, I did not see any results and on top of that it is very heavy and greasy and I did use the smallest amount. It is very rich and thick feeling on the skin. This may be good for someone that has extremely dry skin that doesn’t get oily or doesn’t mind that heavy feeling on their face. I used this product long enough to see that I wasn’t having any noticeable results.

Love the Product - not the price increase

I LOVE LOVE LOVE THIS PRODUCT. It has been part of my daily routine for the last 2 years. However, the price of this has recently skyrocketed. Where I go through almost a bottle a month, it’s no longer part of my budget. It’s unfortunate because it did incredible things for my skin.

[I received this product in exchange for my honest review] Honestly underwhelmed by Paula's Choice C15 Super Booster. First off, the smell is off-putting and even with layering moisturizer I could still smell it on my face. Secondy, I don't believe it had a positive impact on my skin, rather it seemed to age me, making my skin look a bit weathered. The product itself is a silky serum but honestly I couldn't get past the smell.

Great serum!

[I received this product in exchange for my honest review] I love this vitamin C serum! I have sensitive and acne prone skin so I’m usually hesitant to try new products but this is great and I would highly recommend. I like how the dropper comes separately to preserve the product and the bottle is a great size for travel and for everyday. I’ve noticed a difference in the brightness of my skin. Paula’s Choice is great!

Not for me

[I received this product in exchange for my honest review] I didn’t notice any improvements in my skin after using this product. I stopped my normal skin care to give this a real shot. I noticed I developed more blackheads and skin dryness while using. I would not purchase this product again.
