Keeping your skin clean and fresh everyday is important as part of your self-care routine. Identifying what products to use to keep your skin healthy is the first few steps that you need to take before turning them into your daily routine. There is no need, however, to keep all products from a single brand or from a single series.
You can actually combine different products from different series to give the best results to your skin. In the long run, you will be able to see a healthier skin and your skin will definitely thank you for it.
While these are suggested combinations, you are free to explore and research on combining different products to best your skin conditions. If you are unsure, do seek the advice of a professional doctor or dermatologist for the best solution.
