The sequence of applying skincare products is crucial for their effectiveness. When it comes to lip care, the order of application between lip serum and lip balm depends on the purpose of each product.

A lip serum is typically designed to penetrate deep into the skin layers to deliver nourishing ingredients and promote healing and rejuvenation. It is usually lightweight and contains potent active ingredients that can address specific lip concerns such as dryness, fine lines, or loss of volume.

On the other hand, a lip balm is primarily used to seal in moisture and protect the lips from external factors such as cold weather or dry air. It is typically thicker and creates a barrier on the surface of the lips.

Given these roles, it is generally recommended to apply lip serum first, allowing it to absorb and work its magic on a deeper level. After the serum has fully absorbed, follow up with a lip balm to lock in the serum's benefits and provide a protective barrier.

However, it's always important to read the instructions on the specific products you're using, as some might have different recommendations. Also, remember that everyone's skin is unique, so what works best for one person might not work as well for another. Always listen to your skin and adjust your routine accordingly.
