Do I Apply Sunscreen or Moisturizer First? Clarifying Your Skincare Routine
In the realm of skincare, two products stand out as essential guardians of your complexion: sunscreen and moisturizer. These powerhouse products work in tandem to protect and nourish your skin, forming the cornerstone of any effective skincare regimen. Sunscreen acts as a shield, defending your skin against harmful UV rays that can cause premature aging, sunburn, and even skin cancer. On the other hand, moisturizer serves as a hydrating embrace, maintaining your skin's moisture balance and supporting its natural barrier function.
Understanding the significance of these products is crucial for maintaining healthy, radiant skin. Sunscreen's primary role is to absorb or reflect UV radiation, preventing it from penetrating and damaging your skin cells. This protection is vital not only during sunny beach days but also in your daily life, as UV rays can penetrate clouds and windows. Regular use of sunscreen can significantly reduce your risk of skin cancer and slow down the visible signs of aging, such as fine lines, wrinkles, and age spots.
Moisturizer, meanwhile, plays a multifaceted role in skin health. It helps to lock in hydration, preventing water loss from the skin's surface. This is particularly important as dehydrated skin can lead to a host of issues, including dryness, flakiness, and an increased likelihood of irritation. Moreover, well-hydrated skin appears plumper, smoother, and more youthful.

The Great Debate: Sunscreen or Moisturizer First?
The question of whether to apply sunscreen or moisturizer first has been a topic of heated debate among skincare enthusiasts and professionals alike. This seemingly simple query has sparked countless discussions, with passionate arguments on both sides. The confusion stems from the desire to maximize the effectiveness of both products while ensuring they don't interfere with each other's performance.
Those who advocate for applying sunscreen first argue that it should be the closest layer to the skin to provide optimal protection. They contend that applying moisturizer over sunscreen might dilute its effectiveness or create a barrier that prevents the sunscreen from properly adhering to the skin. On the flip side, proponents of applying moisturizer first claim that this allows the skin to fully absorb the hydrating benefits before the protective layer of sunscreen is added.
To further complicate matters, different types of sunscreens – chemical and physical – have led some to believe that the application order might vary depending on the sunscreen formulation. Chemical sunscreens, which work by absorbing UV rays, are sometimes thought to require direct contact with the skin. In contrast, physical sunscreens, which reflect UV rays, are believed by some to be effective even when applied over other products.
The Correct Order: Moisturizer Before Sunscreen
Despite the ongoing debate, dermatologists and skincare experts generally agree on the correct order: moisturizer should be applied before sunscreen. This sequence ensures that both products can perform their intended functions effectively without compromising each other's efficacy.
When you apply moisturizer first, you allow your skin to fully absorb its hydrating and nourishing ingredients. This creates a smooth, well-hydrated canvas for the sunscreen to be applied on top. The moisturizer helps to lock in hydration and strengthen your skin's barrier function, which is crucial for maintaining overall skin health.
Following the moisturizer with sunscreen ensures that you create an uninterrupted protective layer on the surface of your skin. This layer acts as the final defense against UV rays, environmental pollutants, and other external aggressors. By applying sunscreen last, you're also less likely to dilute or disrupt its protective properties, ensuring maximum sun protection throughout the day.

Why Applying Moisturizer First Makes Sense
Applying moisturizer before sunscreen aligns with the general principle of skincare layering: products should be applied from thinnest to thickest consistency. Moisturizers are typically lighter in texture compared to sunscreens, especially physical sunscreens that often have a thicker, more occlusive formula.
This order also allows each product to work optimally:
- Moisturizer absorption: When applied to clean skin, moisturizer can penetrate more effectively, delivering hydration and active ingredients where they're needed most.
- Enhanced skin barrier: A well-moisturized skin barrier is better equipped to retain the sunscreen on its surface, potentially improving its protective capabilities.
- Improved sunscreen application: Moisturized skin provides a smoother surface for sunscreen application, allowing for more even coverage and potentially reducing the risk of pilling or flaking.
Moreover, this sequence can help mitigate some of the potential drawbacks of sunscreen use. Some people find sunscreens drying or irritating, especially when applied directly to bare skin. By moisturizing first, you create a buffer that can help reduce the likelihood of irritation while ensuring your skin remains hydrated throughout the day.
Exceptions to the Rule: When to Apply Sunscreen First
While the general rule is to apply moisturizer before sunscreen, there are a few exceptions to consider. These situations may call for a reversal of the typical order or require a different approach altogether:
-
Prescription topical medications: If you're using prescription skincare products, such as topical acne treatments or retinoids, these should typically be applied to clean skin before any other products. In this case, the order would be: medication, moisturizer, sunscreen.
-
Tinted sunscreens or BB creams: If your sunscreen doubles as a tinted moisturizer or BB cream, it may be designed to be the final step in your skincare routine, replacing both your regular moisturizer and sunscreen.
-
Very oily skin: If you have extremely oily skin and find that moisturizer makes your sunscreen slide off or become less effective, you might consider using a lightweight, non-comedogenic sunscreen on its own.
-
Specific product instructions: Some sunscreens are formulated to be applied directly to clean skin. Always read and follow the manufacturer's instructions for best results.
In these cases, it's essential to pay attention to how your skin responds and adjust your routine accordingly. If you're unsure about the best approach for your specific skin type or concerns, consulting with a dermatologist can provide personalized guidance.

Tips for Maximizing the Effectiveness of Both Products
To ensure you're getting the most out of your moisturizer and sunscreen, consider the following tips:
-
Wait time between applications:
- Allow your moisturizer to absorb for 3-5 minutes before applying sunscreen
- This prevents product pilling and ensures each layer is properly absorbed
-
Sunscreen application technique:
- Use a generous amount (about 1/4 teaspoon for face and neck)
- Apply in a gentle patting motion rather than rubbing
- Ensure even coverage, including often-missed areas like ears and hairline
-
Reapplication:
- Reapply sunscreen every 2 hours, or more frequently if swimming or sweating
- Consider using a powder or spray sunscreen for touch-ups over makeup
-
Choose compatible products:
- Opt for a moisturizer and sunscreen from the same line if possible
- This can help prevent ingredient conflicts and improve overall efficacy
-
Consider your skin type:
- Oily skin: Use a lightweight, oil-free moisturizer and a matte sunscreen
- Dry skin: Choose a richer moisturizer and a hydrating sunscreen formula
-
Nighttime routine:
- Focus on repair and hydration at night when sun protection isn't needed
- Use a richer night cream or facial oil to nourish skin while you sleep
By following these tips, you can create a synergistic relationship between your moisturizer and sunscreen, enhancing the benefits of both products and maintaining healthy, protected skin.

Common Mistakes to Avoid When Applying Sunscreen and Moisturizer
To maximize the effectiveness of your skincare routine, be aware of these common pitfalls:
-
Insufficient sunscreen application:
- Many people apply too little sunscreen, compromising its protective abilities
- Use the "two-finger rule": a line of sunscreen along the length of your index and middle fingers for your face and neck
-
Mixing sunscreen with moisturizer:
- This can dilute the SPF and lead to uneven protection
- Always apply products separately in the correct order
-
Neglecting to reapply sunscreen:
- Sunscreen effectiveness diminishes over time
- Set reminders to reapply, especially during prolonged sun exposure
-
Skipping moisturizer on oily skin:
- Even oily skin needs hydration
- Choose oil-free, non-comedogenic options to avoid clogged pores
-
Using the wrong products for your skin type:
- Mismatched products can lead to irritation or reduced effectiveness
- Consult a dermatologist for personalized recommendations
-
Applying products too roughly:
- Aggressive application can irritate skin and break down product formulations
- Use gentle, upward motions to apply both moisturizer and sunscreen
-
Neglecting other skincare steps:
- A complete routine (cleansing, toning, etc.) enhances overall skin health
- Don't rely solely on moisturizer and sunscreen for all your skincare needs
-
Using expired products:
- Check expiration dates regularly
- Replace sunscreen annually, as its efficacy decreases over time
By avoiding these common mistakes, you'll ensure that your moisturizer and sunscreen work harmoniously to protect and nourish your skin effectively.
The Worst Sunscreen Ingredients You’ll Want To Avoid
The ingredients oxybenzone, octinoxate, octisalate, octocrylene, homosalate and avobenzone are all systemically absorbed into the body after one use, according to studies published by the FDA, which also found that they could be detected on the skin and in the blood weeks after no longer being used.
Previous studies detected many sunscreen ingredients in breast milk and urine samples. In addition, it’s possible for sunscreen users to inhale ingredients in sunscreen sprays and ingest some of the ingredients they apply to their lips, so the ingredients must not be harmful to the lungs or internal organs.
