Do You Put Sunscreen on Before or After Moisturizer? Dermatologists Set the Record Straight
Table of Contents
Whether you're prepping for a beach day or layering skincare before heading to work, one of the most common skincare questions is: do you put sunscreen on before or after moisturizer? Getting this step wrong could reduce your sun protection and compromise your overall skincare routine. In this guide, we’ll break down the science behind SPF layering, explore expert opinions, and teach you how to apply both products correctly for maximum benefit.
Why Skincare Layering Order Matters
The order in which you apply skincare products significantly affects how well they work. Products like moisturizers, serums, and sunscreens are formulated to penetrate or sit on the skin in specific ways. Layering incorrectly can dilute active ingredients or prevent absorption altogether.
As explained by SELF, water-based products should go first, followed by oil-based ones, and sunscreen should be the last step before makeup. Sunscreen’s role is to create a barrier against UV rays, and it needs to remain intact to function properly.
What Comes First: Moisturizer or Sunscreen?
According to dermatologists, the answer is clear: moisturizer first, sunscreen second. Moisturizer is meant to hydrate and nourish your skin, while sunscreen forms a shield to protect against environmental damage. Applying sunscreen after moisturizer ensures it remains undisturbed and forms a protective layer.
The American Academy of Dermatology (AAD) emphasizes that SPF should always be the last skincare step before makeup. This positioning allows sunscreen to perform optimally without being diluted or rubbed off.
The Science Behind Sunscreen Absorption
Sunscreens are categorized into two main types—chemical and physical (or mineral)—and they behave differently on the skin. Chemical sunscreens absorb into the skin and convert UV rays into heat, while physical sunscreens sit on the skin’s surface and reflect UV light.
According to Health.com, chemical sunscreens require clean, bare skin to work effectively. Applying them over a thick moisturizer could block absorption and compromise efficacy. On the other hand, mineral sunscreens are less sensitive to the order of application but still work best when applied last.
Should Sunscreen Go on Bare Skin or Over Moisturizer?
This depends on the type of sunscreen you’re using. Dermatologists generally recommend applying chemical sunscreens to clean skin, then layering moisturizer afterward if needed. However, most people find better results when applying moisturizer first—especially if they use hydrating ingredients like hyaluronic acid or niacinamide.
A good compromise is to wait 3–5 minutes after moisturizing before applying sunscreen. This gives the moisturizer time to absorb and prevents it from interfering with the SPF layer. Harper’s Bazaar suggests gently patting sunscreen on top rather than rubbing it in, especially with physical SPF.
Layering Chemical Sunscreens vs. Physical Sunscreens
The type of sunscreen you use affects when and how it should be layered. Here’s a quick breakdown:
- Chemical Sunscreens: Apply on bare skin or after a lightweight serum. Needs time to absorb (15–20 minutes) before sun exposure.
- Physical (Mineral) Sunscreens: Apply after moisturizer. Sits on top of the skin and offers immediate protection.
As noted by The New York Times Wirecutter, understanding your sunscreen’s formulation helps you layer it correctly and prevents irritation or diminished UV protection.
Can You Mix Sunscreen with Moisturizer? Pros & Cons
It might seem convenient to combine two steps into one, but mixing sunscreen and moisturizer is not recommended. Doing so can dilute the SPF, alter its formulation, and reduce its protective properties.
Dermatologists caution against DIY SPF mixing because you can’t guarantee even distribution or stability. Instead, opt for a moisturizer with SPF if you prefer a streamlined routine. As explained by TODAY Health, you’re better off layering them separately and allowing time between each step.
Does Moisturizer Block Sunscreen Effectiveness?
Moisturizers don’t necessarily block sunscreen, but they can interfere with how well SPF adheres and performs. Heavy or oil-based moisturizers might form a barrier that prevents sunscreen from settling properly into the skin’s surface—especially with chemical formulas.
To avoid this, use lightweight, non-comedogenic moisturizers and apply them sparingly. Let the moisturizer absorb fully (2–5 minutes), then apply a broad-spectrum sunscreen. According to Dermatology Times, this method helps maintain both hydration and UV protection without compromise.

How to Apply Moisturizer and Sunscreen Step-by-Step
Correct application is key to making both products effective. Here's a dermatologist-approved routine:
- Step 1: Cleanse and tone your face
- Step 2: Apply water-based serums (e.g., hyaluronic acid)
- Step 3: Apply moisturizer and allow 2–5 minutes to absorb
- Step 4: Gently layer sunscreen over the moisturizer
- Step 5: Proceed with primer and makeup if desired
According to The Skin Cancer Foundation, always use a nickel-sized amount of sunscreen for your face and apply at least 15 minutes before sun exposure.
Is Sunscreen Moisturizing Enough on Its Own?
Some sunscreens contain moisturizing ingredients like glycerin, hyaluronic acid, or squalane. However, they may not be rich enough for dry or combination skin. If your skin is oily, you might find a hydrating sunscreen adequate on its own.
As stated by Healthline, choosing between using a separate moisturizer or relying on sunscreen depends on your skin's hydration needs, especially in winter or dry climates.
Moisturizer with SPF vs. Separate Sunscreen
Using a moisturizer with SPF can simplify your morning routine, but there are trade-offs. Most experts agree that standalone sunscreens are more reliable because they are designed purely for protection and are typically tested for consistent SPF ratings.
A study cited by BBC Health found that people applying moisturizer with SPF often miss areas like the eyelids or hairline, reducing overall protection compared to standalone sunscreen.
Dermatologists’ Advice on Sunscreen & Moisturizer Order
Top dermatologists consistently recommend applying moisturizer before sunscreen, unless you're using a chemical SPF and require direct skin contact. In that case, a lightweight serum before sunscreen is acceptable.
Dr. Marisa Garshick told Women’s Health that SPF should be the final step in your skincare routine to ensure full coverage and efficacy, especially for broad-spectrum sunblocks.
Sunscreen Before or After Primer & Makeup
Sunscreen always goes before makeup and primers. Apply sunscreen as your final skincare step and give it time to settle before applying any cosmetic products.
As advised by Cosmopolitan, if using a primer, wait 5–10 minutes after SPF to prevent pilling and ensure it doesn’t mix with foundation. Use a patting motion instead of rubbing to avoid disrupting the sunscreen layer.
Mistakes to Avoid When Layering Sunscreen
Even with the right order, common application errors can reduce your sunscreen’s protection:
- Using too little SPF product
- Not waiting long enough between moisturizer and sunscreen
- Applying SPF before letting skincare absorb
- Layering incompatible textures that cause pilling
- Skipping sunscreen indoors or on cloudy days
According to NHS UK, sunscreen should be reapplied every two hours, especially if you’re sweating or exposed to direct sun for prolonged periods.
So, should sunscreen go before or after moisturizer? The expert consensus is: moisturizer first, sunscreen second. This order helps preserve the protective function of your SPF while allowing your moisturizer to hydrate and nourish the skin effectively. Whether you're using a chemical or mineral sunscreen, giving your products time to absorb and layering carefully ensures maximum protection. Avoid common mistakes, stick with dermatologist-approved practices, and you’ll be safeguarding your skin from premature aging and sun damage every single day.
