How Mineral Sunscreen Can Dry Out Your Skin (And What To Do)
Mineral sunscreens have grown in popularity in recent years as an effective and natural alternative to chemical sunscreens. However, some people find that mineral sunscreens can make their skin feel dry, tight, or irritated after application.
While mineral sunscreens offer superb UV protection, their formulations differ from chemical sunscreens and may impact hydration levels in the skin for certain individuals. Understanding why this drying effect can occur and how to mitigate it can help you continue to enjoy the benefits of mineral sunscreen without sacrifice to your skin.
How Mineral Sunscreens Work
Mineral sunscreens mainly utilize zinc oxide and/or titanium dioxide as active ingredients to protect against UV radiation. These minerals sit on top of the skin and act as a physical barrier to reflect and scatter damaging UV rays away from the skin.
In contrast, chemical sunscreens contain filters like avobenzone, oxybenzone, and octinoxate that absorb UV rays and convert them into safer radiation. The chemicals penetrate into the top layers of skin unlike mineral products that remain on the surface.
Why Mineral Sunscreen Can Dehydrate Skin
There are a few primary reasons why mineral sunscreens may sap moisture from skin and contribute to dryness for some people:
Occlusive Effect
The mineral particles sit atop the skin, forming a protective layer that also prevents transepidermal water loss (TEWL) from occurring. This occlusive effect helps keep skin hydrated.
However, for those already prone to dry skin, this may exacerbate the condition by trapping existing moisture in while not allowing optimal moisturizing and hydrating skin care ingredients to penetrate. It blocks skin from both losing and gaining hydration.
Ingredients
Some mineral sunscreen formulas also contain mild astringents like silica or drying ingredients like denatured alcohol. These may pull moisture from the skin over time with repeated application.
Residue Buildup
Mineral sunscreens do not absorb into the skin. Over time, the mineral particles may build up and congeal, leading to a drying, chalky feel on the skins surface.
Frequent Reapplication
To maintain protection, mineral sunscreens typically need reapplied every two hours. Frequently adding layers can increase any inherently drying effects.
Tips to Prevent Mineral Sunscreen Drying Skin
Luckily, a few simple techniques can help you continue using mineral sunscreen without it sapping moisture from your skin:
Choose Wisely
Avoid mineral sunscreens with added drying ingredients like fragrance, alcohol or botanical extracts. Opt for formulas labeled non-comedogenic, oil-free, and for sensitive skin.
Prep Properly
Apply mineral sunscreen as the last step of your skincare routine over moisturized skin. The hydrated base layer helps prevent the occlusive effect. Pat rather than rub when applying.
Use Sparingly
Use a minimal amount needed to achieve protection. Applying too much can lead to chalky buildup. Look for micronized or ultrafine mineral particles.
Remove Completely
Cleanse thoroughly in the evening to wash away all residue to prevent congestion and allow skin to absorb nighttime hydrators.
Moisturize Afterwards
Follow sunscreen application with a hydrating facial mist or lightweight moisturizer to boost hydration without diluting protection.
DIY Hydrating Spritz
Keep a hydrating face spray containing water, hyaluronic acid serum and glycerin on hand for quick moisture boosts over makeup and sunscreen.
Use Cream Formulas
Cream or lotion mineral sunscreens feel more moisturizing. Avoid powders or sticks which feel drier upon application.
Protect With a Hat
Wear a wide-brimmed hat when possible to shade your face and limit repeated sunscreen reapplication.
Other Considerations With Mineral Sunscreen
In addition to potential drying effects, keep a few other factors in mind if mineral sunscreen will make up your primary UV defense:
Coverage Considerations
The thick, opaque mineral barriers can sometimes make it hard to rub in adequately around the eyes, mouth and beard area. Taking extra time to blend and using minimal amounts can help.
Active Time
Minerals start protecting immediately upon application. There is no wait time needed for them to activate like some chemical sunscreens require.
Sun Protection Factors
Mineral sunscreens are able to offer very high SPF protection. Look for options between SPF 30 to SPF 50 for optimal defense.
Reapplication Reminders
Set a phone alarm or timer if needed to remember to reapply mineral sunscreen every two hours when outdoors. Protection does not last all day.
Sting Potential
Mineral sunscreens are less likely to irritate sensitive eyes. They are a good choice if other sunscreens tend to make your eyes burn or water.
White Residue
Unblended mineral sunscreen can leave a visibly white tint on darker skin tones. Take extra time to properly blend to avoid this chalky look.
Balancing Act
Utilize both mineral and chemical formulas as needed to enjoy the best of both options. Rely on mineral for the body and chemical for the face if that helps maximize benefits.
Choosing the Best Mineral Sunscreen
With careful selection and proper use, mineral sunscreens can provide superb sun protection for all skin types without dehydration or irritation. Keep these tips in mind when selecting the ideal mineral sunscreen for your needs:
Skin Type
Choose mineral sunscreen formulated especially for dry, sensitive, or acne-prone skin if these match your skins needs.
SPF Level
SPF 30 or greater provides optimal UV protection. Higher levels indicate greater protection against sunburn.
Active Ingredients
Ensure the formula contains zinc oxide and/or titanium dioxide. These are the only active mineral UV filters approved in the US.
Added Ingredients
Avoid unnecessary irritants and drying ingredients. Seek hydrating oils, glycerin or hyaluronic acid for moisture.
Texture Preference
Consider liquid, lotion, cream, gel, spray or stick formulas. Creams often feel most hydrating.
Fragrance-Free
Choose unscented mineral sunscreens as fragrances can trigger sensitivities for some.
Packaging
Select opaque, air-tight packaging to maintain formula integrity. Seek large volumes to limit waste.
Conclusion
Mineral sunscreens provide an effective, natural sun protection option. While their mineral filters can potentially dry out the skin for some, proper selection and smart application techniques can allow you to reap their benefits without dehydration or irritation. Follow these tips to ensure mineral sunscreen shields your skin without sapping moisture.
FAQs
Why does mineral sunscreen dry out my skin?
Mineral sunscreens can dry some skins by trapping existing moisture in with their occlusive barrier while blocking additional hydration from penetrating the skin surface.
Should I stop using mineral sunscreen if it dries my skin?
You can still use mineral sunscreen by prepping skin properly with moisture first and doing things like rinsing residue off at night. Or you may try alternating mineral and chemical sunscreens.
What's the best way to apply mineral sunscreen?
Apply mineral sunscreen as the last step in your skincare routine after moisturizer. Use a minimal amount and pat rather than rub into skin. Follow with a hydrating face mist if needed.
How can I make my own hydrating face mist?
Mix together purified water, a hyaluronic acid serum, and glycerin in a spritz bottle. Spritz over sunscreen whenever skin feels dry for instant hydration.
Should I use mineral or chemical sunscreen?
It depends on your skin's needs and preferences. Many people opt to use lightweight chemical sunscreens on the face and mineral formulas on the body. Find the best match for each skin area.
