If you think about your skin as if it were a sponge, you want it to soak up all the good stuff you're applying to your face and body. This is why it's important to layer them properly. Use the thinner, more watery products first in your skin routine and finish with the heaviest creams or oils. Oils help seal in any products already applied. So if you're starting with an oil and then adding a lighter hyaluronic acid serum on top, you're not going to see those amazing benefits.
Your hands are REALLY REALLY dirty. Anytime you're just cradling your chin in thought or putting your hand to your cheeks, you're actually leaving a lot of germs behind, and creating a potential zit minefield.
Oily skin isn't something you can fix—it's just something you have to manage. And rather than stripping oily skin entirely or using a super lightweight lotion, turns out the best way to moisturize oily skin is with face oil. The key is to find the oil that suits your own skin type or complexion issues. For example, grape seed oil is lightweight and full of antioxidants, making it ideal for pre-sunscreen hydration. Other oils, like tea tree, can actually fight sebum buildup, bacteria, and inflammation. Some oils even have acne-fighting properties.
I could talk about how important it is to put on on sunscreen before you go outside even on the cloudiest of days. By protecting your skin from UVA and UVB rays, a broad-spectrum sunscreen protects skin from wrinkles and dark age spots (not to mention skin cancer). And if you're worried about SPF breaking you out, just make sure to look for a face-specific SPF that has a "non-comedogenic" label on the tube, which means it won't clog your pores.
