I’ve used this for about 3 months after face washing with another brand- (Tatcha). It does tighten, reduce pores and brighten skin. What it does for collagen prod. the jury is still out.  It’s light weight pat on product which I like BUT IT HAS AN ODOR. 

I've recently become interested in skin care and did a lot of research into the best products for reducing pore appearance and oil control which are two of my biggest skin struggles. This product came up in so many articles and had rave reviews on so many health and beauty sites. I wasn't thrilled about the price, but I've decided to make an investment in skincare and Dermstore was running a sale so I was able to get a good price. Like all Perricone MD products, the packaging is on point. This comes in a glass bottle which makes me happy knowing that I'll be able to recycle it. I didn't notice a terrible smell like some reviews have mentioned. It has somewhat of a strong smell, but it's not something that's detectable once moisturizers or sunscreens have been applied. Additionally, it has helped oil control on my cheeks and forehead which is where I notice my pores are bigger. The main reason I couldn't give a 5 star is because the 2nd ingredient is denatured alcohol which from everything I've researched is not an ingredient you really want to see at all, let alone so high up in the ingredient list. There are also some fragrance components that can be oversensitizing and don't really add anything because this toner doesn't have a super pleasant fragrance. I've had to limit this to once daily use just on my oilier areas because I can definitely see the effect that alcohol is having. I won't plan on purchasing it again - it seems to work, but I would just rather not risk oversensitizing my skin.

I don't know what exactly is in here that makes it work, but it does. I have never used toner before because it seemed pointless. I have huge pores and oily skin and my makeup always gets absorbed and disappears within an hour or two. My makeup stays on all day when I use this because my pores are smaller. The results are noticeable quite quickly. I will keep this as a part of my morning and evening face washing routine. Also, a bottle lasts a very long time.
