“The foundation will be locked in by the setting spray”: the “sandwich” technique that stays put even in the heatwave
Does your foundation slide, fade, or change color after a few hours as soon as the sun comes out? The “sandwich” technique is quickly becoming the most talked-about makeup method of summer 2026. The concept is intriguing, and the results promised by professionals really make you want to give it a try.
The method that’s taking social media by storm
It was professional makeup artist Charly Salvator, known on social media as @charlysalvator, who popularized this approach. He regularly shares makeup tips on TikTok, and his videos on the topic quickly went viral among makeup enthusiasts.
The “sandwich” technique is based on a simple principle: applying layers of setting spray over the foundation to help it stay on the skin longer. This way, your makeup stays in place even in high temperatures.
Charly Salvator says he is a professional makeup artist and has worked with several celebrities, including Marilou Berry, Sylvie Tellier, and Nolwenn Leroy. His professional background lends credibility to his recommendations, going far beyond mere viral trends.
“If you want a complexion that doesn’t budge, especially if it’s very hot with summer coming, you apply a setting spray all over your face.”
A very precise three-step process
The method consists of three key steps: applying the setting spray, applying foundation, and then spraying on another layer of setting spray. It is this layered approach that gives the technique its name.
The first step is to spray a setting spray all over your face. The makeup artist explains that the product should then be blended in with a brush to help it blend into the skin. This prepares the base for foundation.
- Apply a setting spray all over your face before applying any makeup.
- Use a brush to blend the spray into the skin.
- Apply foundation, preferably one with a balancing texture.
- Avoid formulas that are too oily or too matte, depending on your skin type.
- Spray a second coat of fixative spray over foundation.
Choosing the Right Foundation: A Crucial Step
In his explanations, Charly Salvator emphasizes the texture of the foundation used. He points out that in the summer, it’s best to avoid formulas that are too oily, as they tend to cause makeup to run. This point is often overlooked, yet it is key to the success of the method.
On the other hand, very matte formulas aren’t ideal for everyone either. The makeup artist points out that they aren’t suitable for dry or mature skin. He therefore recommends a so-called “balancing” foundation with a medium finish for a more long-lasting result.
Therefore, choosing the right product is just as important as the method itself. Matching the texture to your skin type is the key to ensuring that layering the setting spray is truly effective.
Why Hairspray Plays a Central Role
The second application of the spray, once the foundation has been applied, is the core of the “sandwich” technique. As Charly Salvator puts it: “The foundation will be sandwiched—it will be completely encased in the setting spray.” This explanation clearly illustrates the logic behind the method.
The spray acts as a protective layer around the makeup. In addition, applying the setting spray before and after foundation creates a barrier that minimizes the effects of heat and sweat.
A trend that is taking hold for the long term this summer of 2026
The “sandwich” method is gaining increasing popularity on platforms like TikTok. Professional makeup artists, including Charly Salvator, are helping to spread it to a wide audience. Its simplicity is also a key factor in its rapid success.
This technique requires no special tools or hard-to-find products. All you need is a setting spray and a foundation suited to your skin type. As a result, it’s accessible to everyone, whether you’re a beginner or an experienced makeup user.
The “sandwich” technique addresses a very practical need: maintaining a flawless complexion as the weather gets warmer. Now known far beyond professional circles, this three-step method has become a beauty routine to adopt as soon as the warm weather arrives.
