I would buy this product again!

I have used many facial products throughout my life but I have to admit I have never used a Tricoci facial before, so I didn't know what to expect. I have used the Exfoliate Mask several times now. The bottles states you can use it as a mask to be left on for 30-40 minutes or you can apply it befor...

My sensitive skin doesn't tolerate it

I received this product for free in exchange for my review. The ingredients list is solid. The fragrance is pleasant and the serum feels nice as it's being applied. 10% is the standard beginner dose of vitamin c, and your skin has to adjust…but this severely dried me out. In general, when introducin...

The serum applies smoothly and absorbs quickly. It could have a better scent, as a rose scent just isn't my favorite. A more citrusy undertone would be Bette Ron my opinion. Did not leave a greasy film afterwards.

Bottom Line Yes, I would recommend to a friend

I got this product to try and give my honest review, and I just don't like it. I'm not someone who has sensitive skin and hardly ever have a problem with anything hurting my face but every time I applied this it burned. It's hard to judge how something works when it hurt so bad I didn't want to use it.

Bottom Line No, I would not recommend to a friend

I love the way this product feels on my skin. It's thicker than serums so it doesn't run right off my face. It doesn't really have a scent so that's a plus. I felt like this product brightened my skin some what, but maybe I need more time to see results. If you are wondering, pills under makeup. Overall, a great product! Would recommend.
