The order in which you apply your skincare products is crucial for their efficacy. Here's a general guideline for the typical skincare routine, although keep in mind that individual needs may vary:

1. Cleanser: Start with a gentle cleanser to remove dirt, oil, and makeup from your skin. Use lukewarm water to avoid stripping your skin of natural oils. Repeat cleanse to clean out pores. 

2. Toner: If you use a toner, apply it after cleansing. Toners help to balance the skin's pH levels and prepare it for subsequent products.

3. Serum: Serums are more concentrated and target specific concerns like hydration, brightening, or anti-aging. Apply these lightweight formulations before heavier products.

4. Eye Cream: If you use an eye cream, apply it gently around the eye area. Eye creams often address concerns like puffiness, dark circles, or wrinkles.

5. Spot Treatments: If you're using any spot treatments for acne, dark spots, or other specific concerns, apply them after serums and before moisturizer.

6. Moisturizer: Lock in moisture by applying a moisturizer suited to your skin type. It helps to hydrate and protect your skin barrier.

7. Sunscreen: In the daytime, always finish your routine with sunscreen, even if your moisturizer or makeup contains SPF. Sunscreen protects your skin from harmful UV rays.

8. Oil: At night, finish your routine with a facial oil to help seal in moisture. It is the heaviest formula, therefore, should be applied last.

Remember, allow each product to be absorbed into the skin before applying the next one. This is a basic guideline, but your routine might vary depending on specific needs, concerns, or product instructions. Consulting a skincare professional can provide personalized advice tailored to your skin type and concerns.
