I agree that there is no need to shave and start over. Just let the cheeks grow and in a couple weeks you will barely notice a difference. Beard oil is a great way to keep the skin healthy under your beard, especially if you are washing using a chemical laden shampoo or soap. Which, btw if you are, I suggest you stop doing so and get yourself a bar of Pine Tar soap. The other thing I always suggest for those with dry skin is a diet high in foods with a lot of water content and drinking a lot of water throughout the day. Exercising daily is also great for your skin.
