Clean product
This is a great value for the price you pay for the product. It’s easy to use. It does have a gel type consistency, That’s very easy to put on your face. It does not have any lingering smell or odor. And it does a nice job of helping to absorb extra oil on my face.

Good for oily skin/not overly drying!
Love this!! My skin actually feels a lot less oily during the day and it doesn’t dry my skin out either. The smell is a tiny bit weird but it doesn’t really bother me and it dissipates quickly after applying.

Not for me
This in combination with the aloe-ph balancing face wash was not a good fit for my skin. It had me break out with cystic acne. I went back to Hydro Boost and it cleared up in a week. But that’s for my skin. Also, I didn’t care for the consistency of the product.
