Based on the provided reviews, the Essential Mask Sheet [Honey] by Olivefarm is highly praised for its hydration and affordability. However, there is no explicit mention of whether it can be used every day. Generally, sheet masks are recommended for use 2-3 times a week to avoid over-exfoliation and to maintain skin balance. It's always best to follow the specific usage instructions provided by the manufacturer or consult with a dermatologist for personalized advice.
