How often you should use these skincare treatments will depend on the specific product. Always check the back of the packaging to make sure you’re not overdoing it, which can only make existing skin conditions worse. As a general rule of thumb, apply facial masks 1-3x per week and use facial peels or an At-Home Dermaplaning Tool 1x per week in place of exfoliating. Acne facial treatments and spot creams can cover pimples, breakouts, and maskne whenever they pop up. Most masks and tools should be used after washing your face and applying toner but before serums and moisturizers. Spot treatments, on the other hand, should be applied between moisturizer and sunscreen. If a product contains an active ingredient such as retinol or AHAs, apply during your PM routine to avoid any sun exposure. If you’d prefer to use during the AM, just make sure you’re using ample sunscreen to protect your skin from damage.
