Should You Apply Sunscreen or Moisturizer First?

The debate between applying sunscreen or moisturizer first has been a longstanding topic in skincare routines. It’s not just a matter of preference but involves understanding how these products work and interact with your skin.

This blog post delves into the intricacies of this question, providing a comprehensive guide to help you make the most out of your skincare regimen.

Understanding the Basics

Before diving into the order of application, it’s crucial to understand what these products do:

• Moisturizer: Its primary function is to hydrate and nourish the skin. Moisturizers often contain ingredients like hyaluronic acid, glycerin, and ceramides, which help to maintain the skin’s natural barrier and prevent moisture loss.
• Sunscreen: This is essential for protecting the skin from harmful UV rays. Sunscreens can be chemical, which absorb UV rays, or physical, which reflect them away from the skin. They contain active ingredients like zinc oxide or avobenzone.

The Case for Moisturizer First

1. Absorption: Moisturizers are designed to penetrate the skin, providing hydration. Applying it first allows these beneficial ingredients to absorb more effectively into the skin.

2. Prepping the Skin: A well-hydrated face provides a smooth canvas. This can be particularly important for those with dry skin, as it prevents sunscreen from clinging to dry patches.

3. Maintaining Skin Barrier: Moisturizers help in maintaining the skin’s natural barrier, which can be especially important if you’re using a chemical sunscreen that needs to be absorbed into the skin.

The Case for Sunscreen First

1. Direct Contact: Applying sunscreen first ensures that the protective layer is in direct contact with the skin, which could potentially improve its efficacy, especially in the case of chemical sunscreens.

2. Preventing Dilution: Applying sunscreen on top of moisturizer might dilute its protective properties, potentially reducing its SPF effectiveness.

3. Physical Sunscreens: If you use a physical (mineral) sunscreen, applying it over moisturizer might lead to an uneven application, as these formulas sit on top of the skin and can be influenced by the layers beneath.

The Middle Ground

The order can also depend on the type of products you use. For instance:

• Moisturizer with SPF: A 2-in-1 product might be a solution. However, they may not provide as much protection as a dedicated sunscreen.
• Wait Time: Allowing your moisturizer to fully absorb before applying sunscreen can mitigate many of the issues with layering.
• Texture and Composition: The texture of the products can play a role. Thinner products should generally be applied before thicker ones.

Expert Opinions

Dermatologists often lean towards applying moisturizer first for better hydration and then sunscreen. They emphasize the importance of the final layer of sunscreen being as undisturbed as possible to ensure maximum protection.

Additional Considerations

• Skin Type: Your skin type can dictate your choice. Oily skin might benefit from a lighter moisturizer or even a sunscreen with moisturizing properties.
• Environmental Factors: In environments with high pollution or during summer, sunscreen should be a priority.
• Reapplication: Remember that sunscreen needs to be reapplied every two hours, which might not be practical with moisturizer underneath.

Conclusion: Balancing Protection and Hydration

In the end, the primary goal is to ensure that both hydration and sun protection are adequately addressed. While there might be a slight advantage to applying moisturizer first and then sunscreen, the most important aspect is the correct and generous use of sunscreen, regardless of its order of application.

The debate also highlights a broader point in skincare: understanding your skin’s needs and how different products interact with it. It’s not a one-size-fits-all situation, and what works for one person may not work for another.

Incorporating both products effectively into your skincare routine will not only help in maintaining healthy, hydrated skin but also protect against long-term damage from the sun.

Remember, the best skincare routine is the one you’ll consistently follow, so choose the order that fits best with your lifestyle and preferences, while keeping the efficacy of the products in mind.
