Have you heard of SPF stacking? A new way to apply sun protection

One of the questions that keeps every skincare geek up at night is how much sunscreen to apply on a daily basis. As an essential step in our beauty routine throughout the year, from grey autumn days to the hottest summer months, it is important to understand how to apply it properly so that our skin can enjoy adequate protection against UV rays, which, as we know, are responsible for dreaded photoaging. One of the most talked-about methods in recent months is SPF stacking, a technique that promises effective and comfortable sun protection.

Facial skincare: what is SPF stacking?

Following in the footsteps of the already familiar blush how-to, SPF stacking involves applying and layering two or more facial products containing different sunscreen filters. In practical terms, the goal is to create an even shield capable of protecting areas that are more exposed or often harder to reach. There is one important caveat, though: the SPF values of individual sunscreen products never add up. For example, if you decide to apply an SPF 50 sunscreen before a foundation or skin tint with SPF 15, your final protection will not be SPF 65. The base product remains the primary reference point in terms of sun protection, while the second product can provide an additional layer without guaranteeing a measurable increase in SPF.

Tips for trying SPF stacking

Cleansing and your usual skincare treatments

Before experimenting with SPF stacking, it is best to start with a skincare routine that supports skin health. As always, begin with facial cleansing to remove dirt and excess sebum while respecting the skin barrier. Next, apply a face serum designed to help maintain elasticity and firmness. Finish with a face cream suited to your skin type. At this time of year, you might want to focus on dark spot treatments that brighten and nourish the skin in a single step.

Applying and layering SPF on the face

Once your moisturiser has been fully absorbed, you can move on to layering sunscreen. As always, remember to choose an SPF suitable for your skin phototype and a formula that meets your skin’s needs, whether it is oily, dry or more reactive. Apply a generous layer of facial sunscreen all over your face, making sure to spread it evenly and cover areas that are often overlooked, such as the eye contour, the sides of the nose and the ears. Wait a few minutes for the product to be fully absorbed, then follow with a liquid or compact foundation containing SPF. Throughout the day, whether you are at the office or out and about, reapply sunscreen every two hours to maintain adequate, consistent protection. In this case, you can use a sunscreen spray that can be applied over makeup in just a few quick steps.
