Keeping makeup in place during summer can feel like an impossible task. A foundation that looks flawless when applied in the morning often starts to fade, separate, or become shiny after just a few hours in the heat. Whether you’re commuting, spending time outdoors, or simply dealing with rising temperatures, maintaining a fresh-looking complexion can quickly become a challenge.
That’s why a simple technique shared by professional makeup artists is attracting so much attention online. Known as the “sandwich technique,” this easy method is designed to help foundation stay put for longer, even on particularly warm days. It doesn’t involve complicated products or a lengthy routine.
Summer Is Often the Ultimate Test for Your Makeup
Hot weather can dramatically affect the way makeup wears throughout the day. As temperatures rise, the skin naturally produces more oil and sweat, which can cause foundation to break down more quickly. The result is often unwanted shine, patchiness, or makeup that seems to disappear from certain areas of the face.
Many people try to solve the problem by layering on more products. However, beauty professionals often recommend the opposite approach. During warmer months, lighter skincare and makeup routines tend to perform better because they place less stress on the skin.
This is one reason why lightweight moisturizers, gel-based formulas, and breathable complexion products have become increasingly popular. The goal is to create a smooth base without adding unnecessary layers that may struggle to hold up in the heat.
Choosing the right foundation also matters. Products that are overly rich can feel heavy and may move more easily throughout the day, while ultra-matte formulas can sometimes look dry or emphasize skin texture. Many makeup artists suggest opting for formulas that strike a balance between matte and radiant finishes.

The “Sandwich Technique” Takes Just Seconds to Do
The technique gained popularity after being shared by French makeup artist Charly Salvator, who regularly posts beauty tips on social media. Despite its unusual name, the process is surprisingly simple.
The first step is applying a layer of setting spray directly onto the skin before foundation. Once sprayed, the product is blended lightly so it sits evenly across the face. Foundation is then applied as normal.
After completing the complexion, a second layer of setting spray is applied over the finished makeup. This creates what makeup artists refer to as a “sandwich effect,” with the foundation positioned between two layers of setting spray.
According to supporters of the technique, this helps makeup bond more effectively with the skin and improves overall wear time. The method has become especially popular among people looking for ways to keep their foundation looking fresh during heatwaves, outdoor events, and long summer days.
A Viral Beauty Hack That Actually Makes Sense
Part of the reason this technique has resonated with so many people is its simplicity. Unlike some viral beauty trends that require a long list of products or advanced skills, this one can be tested with items many people already own.
It also fits into a broader beauty trend focused on maximizing results without overcomplicating routines. Rather than adding more layers of makeup, the sandwich technique works by improving how existing products interact with the skin.
