Unfortunately, if you have a product that you love oh so much, it’s not going to work forever. Well, not if you never change things up. Eventually, your skin will adapt to the active ingredients in the products that you use making them less effective over time. Also, your skin changes. So, something that worked for you in the past or present may not in the future. That’s why it’s important to know your skin type so you can switch up your skincare routine when necessary.
