Apply merchandise within the appropriate order
One necessary approach to make sure that you’re actually protected against harmful UV rays is to use your sunscreen because the final step in your morning skincare routine, however earlier than you start making use of any make-up.

After you wash your face within the morning and apply any skincare merchandise, like toners, serums, moisturizers or oils, slather in your sunscreen. Dermatologists suggest utilizing a minimal solar safety issue of 30.
Put on sufficient sunscreen
Studies have found that individuals usually don’t use sufficient sunscreen for ample safety. Most solely apply 1 / 4 of the quantity that they want for his or her complete physique, mentioned Dr. Amanda Doyle, a dermatologist on the Russak Dermatology Clinic in New York Metropolis. You want about two milligrams of sunscreen per square centimeter of skin to realize the marketed SPF, based on the Pores and skin Most cancers Basis.
As a result of everyone seems to be completely different, this might imply kind of sunscreen relying on the scale of your face. To make utility somewhat simpler, Tiara Willis, a New York-based aesthetician, recommends the two-finger rule (lining the size of your center and index finger with sunscreen) to measure an ample quantity of sunscreen on your face and neck.
Let it set
Earlier than making use of any make-up on prime of your sunscreen, give it at the least two minutes to sink into the pores and skin. Keep away from touching your face throughout this time. Dr. Kiran Mian, a dermatologist at Hudson Dermatology & Laser Surgical procedure in New York Metropolis, mentioned that including make-up too quickly might dilute your sunscreen or work together with the components, rendering them ineffective.

Dr. Mian recommended doing one thing like brushing your eyebrows after making use of sunscreen to maintain your self busy within the interim. In case your sunscreen base is correctly dried and set, the components in your make-up shouldn’t negatively have an effect on its SPF.
Don’t depend on basis with SPF
Many foundations, magnificence balms and color-correcting lotions include sunscreen, which might seem to be a handy option to shield your pores and skin with out compromising your make-up routine. Nonetheless, make-up with SPF isn’t adequate as your sole sunscreen possibility since you’d want to make use of a number of it — greater than most individuals usually use for his or her on a regular basis appears — to successfully shield your pores and skin.
In fact, it doesn’t harm to have added SPF out of your make-up, as a result of, on the subject of sunscreen, extra is extra. One study published in 2021 even concluded that layering make-up over sunscreen boosted whole solar safety. It’s because all make-up, even merchandise that don’t have built-in SPF, comprises filters just like these present in bodily sunscreens, which might present added safety in case your sunscreen base layer isn’t adequate.
Reapply sunscreen often
Sunscreen needs to be reapplied each two hours, or after swimming or sweating. Even sitting close to a window whilst you work requires reapplication, as a result of glass doesn’t considerably block UVA or UVB rays. Often, reapplication is so simple as smearing on one other coat of sunscreen, however it may be trickier once you’re sporting make-up.
The considerably disappointing information: There aren’t sufficient research to show simply how efficient SPF reapplication on prime of make-up is. And there’s cause to suppose it’s not excellent, as a result of we all know that sunscreen is handiest when utilized as near the pores and skin as doable and since it’s difficult to use sufficient sunscreen over make-up to be sufficiently protecting. Powder sunscreens, for instance, are an attractive possibility for reapplication due to their portability and utility as a fast touch-up instrument, however in actuality, mentioned Dr. Cula Svidzinski, the medical director of the Pores and skin of Colour Heart at Mount Sinai Medical Heart, you’d want to use a few teaspoon of powder sunscreen in your face to achieve the marketed SPF.
SPF setting sprays, and spray sunscreens normally, are interesting for his or her simple utility, however the fact is that they nonetheless must be rubbed into the pores and skin to supply ample protection from the solar, which negates the presumed comfort.
Additionally, take into account that SPF isn’t cumulative. “In case your sunscreen is SPF 30, and then you definately apply an SPF 15 moisturizer, you don’t have SPF 45 safety,” Dr. Mian mentioned.
So, what must you do? Specialists say that it is best to use any methodology that may encourage you to reapply your sunscreen, as long as you perceive that you just most likely received’t be getting the complete marketed SPF. Whether or not you reapply with a powder sunscreen, drown your face in an SPF setting spray or squirt sunscreen lotion onto the again of your hand and pat it on over your make-up, even a small SPF increase is best than nothing, the specialists mentioned.
