I decided to purchase this face serum after reading the reviews (on several sites). I needed an extra boost for my oily, acne prone skin. After cleansing my face in the morning (dermalogica medibac cleanser), I apply a small amount all over my face, careful to avoid the eye and lip area. I let my sink absorb the serum and apply my moisturizer afterwards. In a week, I've noticed how much smoothr my skin feels, it feels tighter, my breakouts have decreased, and overall, it looks healthier. My night routine is the same as my morning routine. I definitely recommend this product!
