great light weight serum
this is a great light weight serum that wears well under sunscreen and makeup. I dont know that it did a whole lot but it may have helped at keeping my acne at bay. It just expired too fast before i got to finish it all :-( But it was great while i could use it.
Report this reviewAnother PC product that I tried that has no effects on pores
I have tried multiple products from PC to try to reduce the size of my pores and improve skin textures. However, none of them have done it and neither has this one. The texture of this serum is also a bit too heavy for the summer.
Report this reviewBrightening
This is nice. It did help maintain minor problem areas. It's not overly strong, either. I'd recommend it to those with sensitive skin.
Report this reviewNo difference
Application is smooth and works well under make-up, but didn't see ant difference after finishing a whole tube. I prefer other antioxidant serums.
Report this reviewNice product!
Controlled a seasonal little breakout. Absorbs very well and doesn't affect the application of other products after it. Doesn't smell bad. I really like it and would recommend for oily and enlarged pores skins.
Report this reviewGood? Probl
Like it, absorbs very fast. I used it every day but still got blackheads going on just like before using it.
Report this reviewHow do I love thee? Let me count the ways!
This is such an incredible product. I wish I had started using it ages ago. The antioxidants in this really do brighten up my face. It's like my skin is sun kissed. And the extra little big of BHA has really refined a lot of my stubborn pores. The texture of this is very enjoyable. It's thin and easy to spread. And, it feels lightweight. This was very easy to integrate into my routine. The results are fantastic. I HIGHLY recommend this.
Report this reviewQuality serum
I got this as a sample, and used the whole sample. It seems like a good salycilic acid serum but ultimately not amazing enough to justify the price.
Report this reviewNo notable difference in my skin
I struggle with blackheads and congestion and am always searching for a product to add to my routine that combats that. I have no complaints about the serum itself, I just didn't notice any visible improvement in my skin's texture or clarity while using it.
Report this reviewRefreshing Serum
I look for serums to be hydrating without feeling heavy. This sinks right into the skin but my skin doesn't feel dry at all. Will definitely repurchase.
