When I get up in the morning, I rarely wash my face, instead opting for micellar water before applying sunscreen. Then, after I workout, I may not immediately hop into the shower, especially if I've squeezed a class in between work assignments.
However, I am still careful to (at the very least) wash my face soon after Spinning, and I absolutely love the Laneige Cream Skin Milk Oil Cleanser ($34) at this time. This face wash has a low pH of 5.5 — skin is on average around a 5 — so it can help rebalance my complexion to its optimal point after a sweaty workout. Plus, just having a clean face goes a long way if I've got to send just one more email before getting fully washed up.
