Do I need to apply sunscreen if my primer and foundation have SPF?

In most cases, the answer is yes, you should still apply sunscreen. While many primers and foundations nowadays come with SPF/PA ratings, the level of protection they offer is often insufficient.

The issue is that we typically use a very small amount of primer and foundation, and to achieve the stated sun protection, one would need to apply 2mg/cm² of skin – which is not feasible with a typical makeup application. Moreover, the sun protection offered by these products is relatively weak. Primers are meant to correct skin tone and prolong the wear of your base, while foundations primarily conceal imperfections and even out the skin tone.

Therefore, no other product can truly replace a dedicated sunscreen. Only a specialized sunscreen can effectively protect your skin from UVA/UVB rays, which are the main culprits of sunburn, skin darkening, and premature aging.

You should still apply sunscreen even if your foundation and primer have SPF.

Under what circumstances can you skip sunscreen?

If you’re using a tinted primer with sunscreen, marketed as an “all-in-one” product, with an SPF of 30 or higher and PA+++ or more, and you apply a sufficient amount as recommended, then you may skip the separate sunscreen step if you’re only going to be briefly exposed to mild sunlight.

However, if:

– You spend a significant amount of time outdoors

– You are directly exposed to intense sunlight for prolonged periods

– You wish to more effectively combat UV-induced aging

– You want comprehensive protection, including your neck and décolletage

It is advisable to apply a dedicated sunscreen before your makeup. This step remains crucial if you’re serious about safeguarding your skin.

If your foundation offers sufficient sun protection and you’re only going to be outdoors for a short period, there’s no need to apply additional sunscreen.

What’s the correct order for applying sunscreen when wearing makeup?

Applying sunscreen in the correct order is key to optimizing skin protection and ensuring a smooth base for your makeup. The ideal routine is: skincare → sunscreen → primer → liquid foundation. This approach not only safeguards your skin from UV rays but also ensures your makeup stays put without caking or smudging.

Applying sunscreen before primer and foundation prevents smudging and ensures your makeup stays flawless.

What to avoid when using sunscreen.

How can I reapply sunscreen without ruining my makeup?

Reapplying sunscreen is crucial to maintaining adequate sun protection throughout the day. Even if you’ve applied sunscreen in the morning, it can be rendered ineffective by sweat, sebum, or friction, especially on hot days or during physical activities. Therefore, reapplication is essential if you want to truly shield your skin from the sun’s harmful rays.

The frequency of reapplication depends on your lifestyle and environment: for those who work indoors, a single touch-up at noon should suffice. Conversely, if you spend a lot of time outdoors, reapply every two hours. If you engage in strenuous activities or perspire heavily, reapplication should be more frequent. Notably, reapplying after 30 minutes significantly boosts sun protection.

Here’s how to reapply sunscreen without disturbing your makeup:

– First, gently blot away excess oil and sweat with blotting paper or a soft tissue to keep your base matte and prevent caking.

– Choose the right sunscreen format for reapplication: sunscreen sprays (convenient and quick), cushion/powder sunscreens (ideal for touch-ups on specific areas), or liquid sunscreens applied with a makeup sponge for even coverage.

Only by understanding and diligently practicing sunscreen reapplication can you maintain healthy, radiant skin and effectively prevent skin darkening, sunspots, and premature aging caused by sun exposure.
