Wondering if you should try skin fasting? Skin fasting may benefit your skin because it gives your skin time away from ingredients that can trigger inflammation. Some beauty experts say that skin fasting is more beneficial if you have dry or sensitive skin, but you can give it a try if you feel like your skin needs a reboot. However, before trying it out for yourself, it’s recommended you consult your doctor to rule out complications. Especially if you have skin disorders like acne, rosacea, melasma, or eczema, or a skin condition that requires topical products, skin fasting is not recommended.
