To layer skincare products effectively, it is important to follow a few general rules. The first rule is to apply products from thinnest to thickest, allowing each layer to fully absorb before applying the next one. This ensures that each product is absorbed fully and prevents them from piling up on top of each other. The second rule is to apply products with the highest percentage of active ingredients first, so that they are absorbed first. Here are some tips for layering skincare products:

1. Start with a clean slate: Before you start layering products, make sure your skin is clean and free of any dirt, oil, or makeup. Use a gentle cleanser to remove impurities and prep your skin for the products to come.

2. Apply toner: After cleansing, apply toner to balance your skins pH levels and prepare it for the next steps.

3. Apply serums: Serums are designed to deliver high concentrations of active ingredients into the skin, so apply them first. Start with the thinnest, fastest-absorbing serum and layer the next heaviest over it, then the next, so that the thickest formula ends up on top.

4. Apply eye cream: Apply eye cream before moisturizer, as it is usually thinner and lighter in consistency.

5. Apply moisturizer: Moisturizer helps to lock in moisture and keep your skin hydrated. Apply a moisturizer that suits your skin type and concerns.

6. Apply facial oil: If you use facial oil, apply it after moisturizer to seal in the moisture.

7. Apply sunscreen: Sunscreen is the last step in your skincare routine, as it helps to protect your skin from harmful UV rays. Apply a broad-spectrum sunscreen with an SPF of at least 30.

It is important to note that you might not need all of these steps, and you should adjust your routine based on your skin type and concerns. Also, be careful not to layer incompatible skincare products, as this can decrease their effectiveness and cause skin irritation.
