Daily facial sun care: a beauty and longevity gesture not to be overlooked
Do you know all the benefits of sun protection ? In addition to preventing skin diseases and sunburn, it protects the skin from harmful rays responsible for photoaging and skin reactions due to the sun.

Which sun care should you choose for daily application?
How to choose a facial sunscreen that is suited to your skin type and incorporate it into your daily routine? Here is an overview of the different types of sunscreens available to help you see things more clearly.
Types of sunscreen: understanding their differences to provide optimal skin protection
Chemical vs. Mineral Sunscreens: Which to Choose?
- A chemical filter sunscreen contains organic UV filters that absorb UV rays. It is pleasant and very easy to apply, leaving no white marks, which makes it very popular with dark to matte skin . However, this type of filter is not suitable for sensitive skin. In addition, some chemical filters are identified as endocrine disruptors, or have been associated with damage to coral reefs and marine life.
- A mineral filter sunscreen uses physical filters like zinc oxide and titanium dioxide to reflect and diffuse UV rays. These particles form a barrier on the surface of the skin. It is more recommended for people with sensitive skin, or children. Mineral filters provide immediate sun protection against sunburn. In addition, mineral filters are more environmentally friendly and do not damage coral reefs.
Sunscreens vs. Moisturizers with Built-in SPF
Some cosmetic treatments (oils, serums, creams or even tinted treatments) include an SPF in their formula. It may be tempting to turn to these products as a replacement for sunscreens, but in general the amount of SPF and UVA protection is not sufficient to block harmful rays. In addition, you would have to apply a very large amount of cream to benefit from optimal sun protection.
Sun Protection Factor (SPF): Dermatological Recommendations
SPF, or Sun Protection Factor, is the level of protection given to sunscreens. A minimum SPF30 is necessary if you go outside. But for children and sensitive skin, an SPF50 is essential. In general, dermatologists advise following these 3 rules:
- Do not expose yourself between noon and 4 p.m.
- Use a sunscreen with at least SPF 30+.
- Renew the application regularly .

Key ingredients in the composition of sun protection
Not all sun care products are equal, and the active ingredients they contain often vary from one product to another. So which ones should you choose for your skin type or, on the contrary, avoid?
- If you have combination, oily or acne-prone skin, opt for a facial sunscreen for oily skin or a non-comedogenic sunscreen , which contain mattifying active ingredients .
- For sensitive or dry skin, choose moisturizing and soothing ingredients .
- Finally, avoid certain controversial chemical sunscreens that are very present in sunscreen products such as avobenzone, octocrylene or octisalate. They can cause irritation and have a negative impact on the environment.
Misconceptions about sun protection
You've probably heard one of these phrases before: so, myth or reality? We'll explain everything to you!
"I don't need sunscreen if it's cloudy"
This is false. Cloudy weather does not mean safe. UV rays are not stopped by bad weather conditions and several studies demonstrate the importance of sun protection even on cloudy days.
"My skin is dark, I don't need sunscreen"
This is false. All skin types are sensitive to the sun's rays, especially dark and olive skin, which are most affected by hyperpigmentation problems.
