I no longer suffer from acne but whenever I get the odd spot it does leave a scar (dark patch) sometimes its also nice to have brighter clearer skin especially in the summer months when its hot and humid. If you have sensitive skin or delicate skin then you may find that not all products suit your skin, I find that some face masks end up giving me spots rather than stopping them from appearing!
After research and trying out different things myself the best homemade face mask that works for me is Turmeric and Honey. Please note that I have tan skin but from what I hear even fair skin can use this mask, it does not stain! It just makes you glow and cleans the skin.
