Which sequence correctly describes product application in the Protect step?

• A. Thickest to Thinnest
• B. All Products at Once
• C. Thinnest to Thickest
• D. In Random Order

Answer: (C)

In facial treatment layering, you apply products from the lightest texture to the heaviest. In the Protect step, this means starting with the thinnest formulas (like a hydrating toner or essence) and finishing with the heaviest (such as a rich moisturizer or occlusive protection). This order lets each layer absorb properly and then seals in moisture without blocking lighter products from penetrating. So the best sequence is applying from thinnest to thickest. If you started with a thick cream, lighter layers wouldn’t absorb well, and applying everything at once would prevent proper layering. Random order or reversing the sequence would similarly disrupt absorption and result in less effective protection. A practical example would be toner or essence first, then a light serum, then a moisturizer, and finally sunscreen or a protective layer if it’s daytime.
