Much more than a summer accessory, sunscreen should be the essential treatment to adopt in your routine, all year round. At TOPICREM, we provide very high protection to your skin every day, through a selection of dedicated treatments.

Understanding the effects of UV rays

The sun's rays come in several distinct categories, each with specific implications for skin health:

  • UVA rays are associated with premature aging of the skin . They can penetrate deep into the skin , causing premature aging, loss of firmness , and contributing to the development of age spots . And if you didn't know yet, they pass through clouds and windows.
  • UVB rays , most intense between April and September, especially from 10 a.m. to 4 p.m. , are the main cause of sunburn . They act on the surface of the skin, causing redness or burning .

Everything you need to know about SPF

First of all, understanding the meaning of protection factors is essential to choosing the sunscreen suited to your needs. If you browse our HYDRA + , MELA and CALM+ ranges you will see this acronym appear: SPF , meaning “Sun Protection Factor” in French. This index is a key element to take into account when choosing your cream.

  • SPF 30 blocks 95% of UVB rays,
  • SPF 50 increases this protection to 98% .

The difference between SPF 30 and SPF 50 is minimal .

The TOPICREM guide to choosing the right protection

1. Choose a suitable SPF:

  • First, make sure the sunscreen offers broad-spectrum protection , meaning it protects against both UVA and UVB rays.

  • To make your choice easier, know that the SPF index indicates the level of protection against UVB rays . The higher the SPF rating, the greater the protection against sunburn.

  • To identify protection against UVA, responsible for skin aging, look for the circled UVA logo or the PA logo followed by + .

  • For daily protection, we suggest opting for a cream with a protection factor of at least 30 . However, if you plan to spend a lot of time outdoors , opt for a higher SPF, such as 50 or even 50+ .

  • 2. Look for effective and approved active ingredients

    Beyond sun filters, choose products containing additional active ingredients ensuring internal biological protection of your skin cells (echinacea extract, vitamin E, etc.).

    Prefer compositions that have been rigorously tested to assess their impact on marine biodiversity , thus ensuring that this will be as minimal as possible.

  • 3. Consider your skin type

    If you have sensitive or allergy-prone skin , look for formulas that have been tested on this target . For oily skin , opt for non-comedogenic, lightweight formulations that won't clog pores. Explore our SUN PROTECT range , designed to meet the needs of the most delicate skin.

    Also adapt the choice of your protection to your needs and your phototype , this allows you to classify your skin according to its reaction to the sun and its sensitivity to UV .

4. Consider water resistance

If you plan to swim or sweat, choose water-resistant sunscreen and reapply it regularly , especially after swimming or sweating.

The essential steps to properly apply your sunscreen

On summer days, sunscreen naturally joins your ritual. And yet taking care of your skin and protecting it daily is essential.

How much sunscreen to use for protected skin?

In practice, many users tend to underestimate the recommendations of dermatologists: generous application is essential for optimal protection against UV rays.

The ideal is to cover our entire body with 35 g of sun protection, which is equivalent to 7 teaspoons.¹

TOPICREM tip:

Apply a generous line of sunscreen from the tip of your middle finger to your wrist , which you then apply to each part of the body. For spray sunscreens, this amounts to 15 sprays on each area of ​​your body. And your skin will be protected.

What sunscreens should you avoid?

Certain ingredients and formulations found in sunscreen should be avoided due to their potential impact on your health and the environment . Here is a brief list:

  • Octocrylene is a filter against UV rays which, over time, transforms into benzophenone and can therefore become dangerous. This compound has potential as an endocrine disruptor due to its modest estrogenic activity, and it is also associated with many allergic reactions.

  • Oxybenzone and octinoxate : These ingredients used as UV filters are present in many sun creams. Upon application, they are absorbed by the skin, metabolized and excreted. These compounds can cause skin allergies and some also consider them to be harmful to coral beds .

  • Untested and unsuitable: If you have sensitive skin , we recommend that you ensure that the product has undergone dermatological testing, particularly suitable for your skin type.
TOPICREM advice:

After expiry dates, certain components may present health risks. A practical tip: sometimes solar products display a pictogram representing an open jar accompanied by a number followed by the letter “M”. This indication represents the duration in months during which the product can be kept after opening. In any case, it is not recommended to use a sunscreen product from one year to the next.


Practical, simple, but essential , sunscreen should not be a summer option, but an essential all year round . Make the health of your skin a priority with products adapted to its needs and take full advantage of each sunny day with complete peace of mind.
