Highly recommend for oily skin
The best for oily acne prone skin!! I have tried multiple face cleanses but nothing matches this! My face was broken out and in 2 days I could tell a huge difference. 5 days later my breakout is completely cleared up! Highly recommend using after you remove your makeup and then again the next day before reapplying your makeup! I will be buying again and again for sure

Effective
I normally do not have oily skin, however lately my forehead and nose have been super oily and it's driving me crazy! Maybe I overdid it with tons of new skincare I've been trying out. I recently got the Thayer's milky toner and I love it so so much, but I thought I should try this one instead because my face gets greasy halfway through the work day lately. I've been using this after washing my face before bed and when I wake up and I think it is working so well to reduce the oily skin. It's also this really unique jelly texture and feels cool and smooth on my skin

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.
