If you open up anyone's medicine cabinet, look on their sink, or in their shower, you're apt to find lots of different products from different brands. But when it comes to skincare products, is it ok to use different skincare brands at the same time? Many skincare lines suggest that you should only use their products since you're assuming that the company has tested that the different products are compatible with each other. Even so, this does not mean that you can only use one company's products exclusively. There's nothing wrong with using different skincare products from as many different skincare companies as you'd like, as long as two conditions are met. The product has to be appropriate for your oil and water skin type, and you have to like the way the product feels on your skin!
