I used the entire tube of this product. I never noticed a difference and the smell was horrible, almost metallic. I am kind of sensitive to smells so I gave it a chance to see if it was 'just me'. No, It kinda tingled on my skin at first and then left this horrible smell on my hands in which I had to wash and then it made me feel like I had to wash my face. Not for me.

Not my favorite product
Sampled

I'm getting up there in age (I'm 26), and I'm currently in the market for anti-wrinkle products. My skin is a fickle beast, and because of that I need something for sensitive skin, acne and dry skin.

Unfortunately, this product made my skin burn and turn red. I still had to use a moisturizer afterwards, and when I woke up the next day, I didn't really see a difference. My skin is still uneven, and I did experience some minor clogged pores.

Middling strength, middling results
Sampled

Other Vitamin C serum at 20% strength are much better, I use one regularly. Try Benev's version.

Too young to see any results
Sampled

I'm fairly young and luckily dont have many wrinkles so I cant really say if this works or not. The texture of the product felt really smooth and went on real light and non sticky.

Wimpy sample
Sampled

Unfortunately I can't really leave much of a review for this product considering hpw wimpy the sample size was. I am sure this is something that needs to be used for at least 4-6 weeks to see results, but I'm not going to spend that kind of money without knowing for sure that it would reduce my fine lines and wrinkles. It moisturized, I suppose, but was a tad greasy feeling where I use it, trying it out on this large wrinkle I have across my forehead, which is also the only spot on my face that ever gets "greasy." I say "nay" to this product.

Nice primer
Sampled

This works well as a primer, but isn't particularly moisturizing.

eh
Sampled

So pretty much it made my skin feel way to slick and greasy, like i had a layer of goop on. I found my pores to be more clogged than i started with and i felt that it was just filling my wrinkles in like a primer not actually helping to reduce them. on top of that the sample was too small to decide if this would work long term.

Brand is not for me
Sampled

I feel most of the products that this brand offers are quite oily, whether lotions or facial serums. Also, the scent, although faint, reminded me literally of PineSol. Lastly, and I'm the first to admit I have super sensitive skin, this product caused a consistent stinging sensation upon application. Definitely not for me.
