Enter Differin Gel, the first retinoid gel to be approved for over-the-counter use.

Topical retinoids are prescribed for almost all patients in the office, Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City, has previously told Allure.
Based on my calculations and experiment, here is some information on boiling water in a microwave: Time to bring to boil 3 cups of room temperature water in a microwave, by watts: 700 watts: 8 min 30 sec. 1000 watts: 5 min 57 sec.
It takes quite a bit of energy to bring water to a boil. In fact, you need 1 calorie of energy to raise 1 gram (0.03 ounces) of water by 1 degree Celsius (1.8 degrees Fahrenheit). In order for water to boil, its vapor pressure has to equal the pressure of the atmosphere, Giddings said. That's partly why water boils at a lower temperature on top of Mount Everest than it does at sea level. There's less atmosphere, or lower pressure, pushing down on the water on the mountain, at 29,000 feet (8,800 meters), she said. However, let's envision a pot of water on a burning stove at sea level.
