I can't stress enough how important exfoliation is. In order for us to have healthy and glowing skin, skin cell turnover must be healthy. When new skin cells are formed at the base and deepest layers of skin they are round and full of nutrients. As they slowly make their way to the outermost layers of your skin, they become flattened and slowly lose water and nutrients. When they reach the surface they are dry dead skin cells that are ready to be sloughed off.
Your body has a natural process to get rid of these cells called desquamation, but various factors can affect it. As we age this cycle slows down. It takes longer for these cells to reach the surface and by the time they make it to the surface they are usually extremely dry and flat. This is why most mature skin is super dry. Sometimes if you have oily skin, dead skin cells can get trapped in your pores and lead to blackheads. The oil kind of acts like glue and cells stick to it.
For these reasons, it's extremely important to exfoliate. Getting all of those dead skin cells off the surface and pulling them out of your pores is crucial. You need the oil in your pores to help protect your skin so you don't want to get rid of it, which is why exfoliation is great for this.
Cell turnover is also extremely important for anyone with hyperpigmentation (dark spots) or discoloration resulting from old blemishes. Exfoliating will aid in helping the appearance of these spots fade as cells are being sloughed off.
While I've talked mostly about your face, let's not forget the body! It's important that you are using a scrub in the shower too. Exfoliating areas where you shave or wax will help with preventing ingrown hairs and ultimately make your skin feel smoother.
As wonderful as exfoliating is, make sure you don't do it too much! No matter what product you use make sure you are reading the directions. Over exfoliation can cause irritation and harm to your skin. Sometimes we can get the mindset that if something is good for us, the more we do it, the more benefits we will see. However, this is not always the case.
Have a beautiful day,
