Which of the following best describes the Protect step product layering order?

• A. Apply From Thickest To Thinnest
• B. Apply All Products At Once
• C. Apply From Thinnest To Thickest
• D. Apply In Random Order

Answer: (C)

In skincare layering, you apply products from the thinnest to the thickest to maximize absorption and prevent pilling. The Protect step often adds a barrier with sunscreen or a protective moisturizer, so it should come after lighter formulas like serums and toners. If a thick Protect product goes on first, it can sit on top and block lighter layers underneath from absorbing properly, reducing effectiveness. Following the thin-to-thick rule lets each layer do its job and then the Protect layer seals everything in. So the Protect step is applied from thinnest to thickest. The other approaches disrupt absorption or skip the layering logic entirely.
