How to use sunscreen
Multistage skin care is effective only if the order of application is correct. With the onset of summer, there is a logical question, how to deal with sunscreen. About that, they are applied before or after the moisturizer, even specialists argue.
“To do its job, a sunscreen with chemical filters must be absorbed into the skin,” said Joshua Zeichner, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York. – In other words, first SPF. Do not use anything that interferes with its penetration. So, a dense moisturizing cream will create a barrier between the skin and the SPF. “
Not all dermatologists agree with this. According to Sejal Sha, a certified dermatologist from New York, SPF should be applied after the morning moisturizer. “Moisturizing cream applied after sunscreen, it can reduce the concentration of the agent with SPF, change its properties and effectiveness, as well as the way ultraviolet rays affect the skin,” she explains.
Also note the type of sunscreen in the product. The type of SPF is another important factor that should be considered when choosing a sunscreen. Means with chemical filters work, absorbed into the skin. Physical (those that leave whitish stains until they are thoroughly rubbed) are protected, creating a layer between the skin and the sun. “Mineral filters (they are often called” blocks “), explains Zeychner. “That’s what they have to do last.”
There are also multifunctional tools. “A lot of moisturizers already contain components to protect themselves from the sun,” says Zeichner. – What kind of scheme to prefer – a moisturizer plus Sanskrin or a combined product – is a personal matter for everyone. “The main thing is that the SPF should be at least 30”.
To stop the debate, it is important to know that technically Sanskrit does not require a combination with a moisturizer. “For most people, the sunscreen is already sufficiently moisturizing itself,” explains Alan Parks, a certified dermatologist, Ohio.
So how do you apply the SPF right up to the moisturizer or afterwards? Both Zeychner and Sha agreed that the option that suits everyone is as follows: first apply a light moisturizer, then allow it to completely absorb – and then use SPF. “In general, I advise you to be safe,” Zeychner says, “First apply a moisturizing cream with SPF, and when it absorbs,” a layer of sunscreen, “whether it’s mineral or chemical.”
