It depends on the product.
Some products are designed for daily use, while exfoliating products and masks may be better used a few times a week.
For example, GLO recommends using the Turmeric Dark Spot Removal Scrub about 1–2 times a week for most people, while the Sea Moss Wrapping Mask can be used 1–3 times a week depending on your routine and hydration needs.
Always follow the directions for the specific product you're using.
