Didn’t see any difference

I love this product and have been using it for years. I apply it on my face after my toner and before I apply my moisturizer. My skin feels perfect all day.

I love this product. I have been using it for years. I have oily skin and large pores. I use this under my makeup and it helps keeps my pores free of make up that causes acne.

I love all of the Principal Secret products. This is a new one for me and it is good or better than all the rest

Love how this tightens my face and gives me a nice glow all day!

Great product. Put it on under moisturizer and my skin looks and feels silky.

I use this for my face. Works on wrinkles and fine lines
