Common Mistakes to Avoid When Layering

While layering can be highly beneficial for your skin, it's important to avoid some common mistakes that may hinder the effectiveness of your routine. Here are a few to keep in mind:
1. Overloading: Avoid applying too many layers of products, as this can overwhelm the skin and prevent proper absorption. Stick to a reasonable number of layers based on your skin's needs.
2. Incompatibility: Be cautious when layering products with active ingredients that may not work well together. Some ingredients, such as retinol and vitamin C, can be potentially irritating when used together.
3. Skipping Patch Tests: Before incorporating new products into your routine, always perform a patch test to check for any adverse reactions or allergies.
4. Ignoring Sunscreen: Sunscreen is a crucial step in any skincare routine, even if you're layering multiple products. Protecting your skin from harmful UV rays is essential for maintaining a healthy complexion.

By avoiding these common mistakes, you can ensure that your layering routine is effective and delivers the desired results.
