What should be applied first when layering skincare products?

The first step in layering skincare products is to apply a cleanser. Cleansing is essential because it removes dirt, oil, makeup, and impurities from the skin's surface, which allows subsequent products to work more effectively. Starting with a clean canvas ensures that serums, toners, and moisturizers can penetrate the skin properly and deliver their intended benefits.

After cleansing, it's common to follow with a toner, then serums, and finally a moisturizer to lock in hydration. Each step plays a crucial role in the skincare routine, but without cleansing, those steps would not be as effective, as residues from the skin would hinder product absorption and efficacy.
