The world of skincare is often steeped in popular beliefs that circulate without any real scientific evidence. To help shed some light on the subject, this article takes a critical look at some common claims, based on advice from expert dermatologists.

1 Do moisturizers make skin "lazy"?

It is often said that regular use of moisturizing creams could make skin "lazy" by reducing its natural capacity to produce sebum. However, this notion is widely refuted by dermatologists.

The application of a moisturizing cream does not stop the skin producing sebum. In fact, if dry skin shows signs of improvement following the use of such creams, it simply means that it adapts better to ambient conditions thanks to the extra moisture provided.

Another frequent question concerns the effect of retinola popular ingredient in anti-ageing products and acne treatments. We sometimes hear that retinol can make skin thinner. But is this really the case?

The question of daily showers also raises a lot of questions. Some people fear that a daily shower may dry out or damage their skin.

Dermatologists recommend avoiding prolonged hot showers to preserve the skin's natural moisture. Gentle cleansers are also recommended, especially for those with particularly dry skin.

By following these precautions, taking a daily shower is not harmful. It even helps to eliminate impurities and maintain optimal hygiene.

4 Should you protect your lips from the sun?

Often overlooked lips are nevertheless highly sensitive to UV rays. As the upper stratum corneum is very thin and lacking in protective pigments, they require special attention.

To avoid sunburn on the lips, it is crucial to use lip balms containing a sun filter, especially for outdoor activities or prolonged exposure to the sun.

This not only helps prevent burns, but also keeps lips supple and moisturized.

5 Are lip balms addictive?

Some believe that regular use of lip balm creates a form of addiction, making lips even drier with each application. This phenomenon is often referred to as a vicious circle.
