Applying a face mask is a great way to pamper your skin. But like serums and moisturizers, it's important to use the correct mask to treat how your skin is behaving to ensure it gets the most from it. Here's how to pick a suitable mask for your skin condition. (1) If your skin is congested, dull, and reacting to environmental factors like humidity, pollution, and heat, an exfoliating mask can help extract impurities and even out your complexion. (2) Use a hydrating, replenishing mask to restore skin health and vitality. If you have problems with fine lines, wrinkles, hyperpigmentation, or stress, a mask that contains hydrating, nourishing ingredients can help.
