Train the ability to know your skin's need for moisture and how much product you need. There can be a big difference in the dosage of moisturizing ingredients such as hyaluronic acid and vegetable oils, depending on the weather, sleep and moisture levels in the air. Especially when it comes to serum, you can easily save a little on the expensive drops in the summer, and then use a little bit more when the temperature drops, during fall and winter.
