Sunscreen: how to avoid clogged pores?

In summer, applyinga broad-spectrum sunscreen is the golden rule for shielding skin from the deleterious effects of UV rays. However, as the weeks go by, a mechanical problem frequently appears: the appearance of imperfections, micro-cysts and a blurred skin texture.

This phenomenon is not inevitable, but a direct chemical consequence. To resist water and perspiration and ensure long-lasting wear, modern sunscreens incorporate highly lipophilic and hydrophobic molecules. These components are designed to cling tenaciously to the stratum corneum. If this adhesion is a victory for photoprotection during the day, it becomes a challenge for evening cleansing. Superficial cleansing leaves a residual film which, when mixed with sebum and pollution particles, clogs pores and asphyxiates the skin.

The chemistry of cleaning: why water alone is not enough

When faced with greasy substances and waterproof filters, a classic cleansing gel or micellar water often proves insufficient. Forced cleansing by excessive scrubbing or the use of harsh surfactants only worsens the situation: it alters intercellular lipids and weakens the skin barrier, triggering low-grade inflammation.

The solution is based on a simple rule of chemistry: like dissolves like. Only an oil phase has the molecular affinity to break the bonds of UV filters and dissolve oxidized sebum without the need for abrasive mechanical action.

PERS evening protocol: The Cleansing Duo

To deeply liberate the skin while respecting the integrity of its hydrolipidic film, we have developed a two-step approach with PERS Cleansing Duo. This protocol synergistically combines two complementary textures:

Step 1: Dissolve with Radiance Cleansing Balm

Applied to dry skin, this creamy balm transforms into an oil when massaged. Its complex of 4 gentle oils instantly fuses with hydrophobic sunscreen residues, make-up and accumulated sebum. Enriched with vitamins C and E and anti-pollution agents, it captures surface impurities. When rinsed off, it emulsifies into a milk, leaving skin perfectly smooth, soft and oil-free, without any occlusive film.

Step 2: Purify with Soothing Cleansing Gel

Once the sunscreens have dissolved, the second step removes hydrophilic impurities (sweat, dust) and the last residues. This fresh gel deeply cleanses pores without ever drying out the epidermis. Formulated with 1% Centella Asiatica and an anti-pollution agent, it instantly soothes thermal inflammation linked to the day's heat, leaving the complexion fresh, clear and even.

Preserved skin, ready to regenerate

Thanks to this double dermal cleansing process, the skin barrier is purified of toxins while remaining biologically balanced. The skin is then in optimal physiological condition: water loss is limited, and cutaneous permeability is restored. It is ready to fully assimilate your night care products, whether in a pure repair phase or the application of your stimulating serum.

Things to remember

Summer pimples aren't an inevitability linked to your sunscreen, but often the sign of incomplete cleansing. By adopting the Duo Cleansing ritual, you eliminate the most resistant UV filters while calming the day's skin stress. Proper cleansing is the first step in protecting your skin.
