As a busy entrepreneur I'm in a constant battle against time and excess face oil. By the end of the day my to-do list has only grown longer, and my face oilier. My highlighter glow turns to a greasy glow--it's gross. Pestle & Mortar's Retinol oil is magic that slows both. It's two forms of retinol (Hydroxypinacolone Retinoate and Retinyl Palmitate) work to undo the appearance of acne scars while the oil-based formula works with my natural sebum to establish an oil-equilibrium. I wake up with fresh, bright looking skin that's smooth and silky, not oily! I recommend this product to anyone looking to control acne, past or future. Just don't forget spf in your morning foundation!
