Cleansing: enhanced barrier for dehydrated and sensitive skin

Facial cleansing: the essential first step in any routine

Facial cleansing is the foundational step of any skincare routine, often underestimated in its importance. Inadequate cleansing alone can compromise the comfort of subsequently applied treatments: excessive cleansing can make the skin uncomfortable and alter its feeling of suppleness, while insufficient cleansing leaves residues that dull the complexion. Yet, this step rarely receives as much attention as the choice of a serum or cream.

Throughout the day, the skin accumulates several categories of "dirt": sebum, perspiration residue, atmospheric pollution (PM2.5 particles, ozone, nitrogen dioxide), makeup and sun filters, and daily impurities. The goal of cleansing is to remove these elements while preserving the skin's comfort and apparent balance. Even brief exposure to alkaline or aggressive cleansers can be enough to make the skin uncomfortable and dull the complexion for several hours.

Skin pH: why a cleanser should be slightly acidic

The skin's natural pH is generally between 4.5 and 5.5 (slightly acidic). This acidic environment supports several aspects of skin comfort: it contributes to the skin's apparent balance, aids in the natural renewal of the skin's surface, and helps maintain a feeling of suppleness. A classic soap with a pH of 9-10 or a facial cleanser with a pH of 7-8 can disrupt this acidic balance, with consequences for skin comfort and appearance.

pH disturbance alkalizes the skin and can create a sensation of discomfort as well as a dull appearance. Returning to the natural pH takes from 30 minutes to 2 hours, depending on the extent of the aggression. Choosing a cleanser formulated at pH 4.5-5.5 (or a maximum of 6-6.5) is therefore an essential selection criterion, even before the ingredient list.

Types of cleansers: characteristics and indications by skin type

The facial cleanser market is vast and often confusing. Here is a functional classification. Foaming gel cleansers are the most common. Those formulated with mild surfactants (coco glucoside, lauryl glucoside, sodium lauroyl sarcosinate) are suitable for normal to oily or blemish-prone skin. Formulas with SLS (sodium lauryl sulfate) should be avoided for all skin types, especially dry and sensitive ones. Creamy or milk cleansers contain emollients (oils, butters, esters) that maintain comfort during cleansing. They are suitable for dry and mature skin. Cleansing oils dissolve oily substances (sebum, waterproof makeup) by the principle of similarity. They emulsify upon contact with water and rinse off easily. Paradoxically, they are also suitable for oily skin (solubility principle: oil dissolves oil). Micellar waters contain micelles (spherical aggregates of surfactants) that capture impurities. They cleanse without rinsing but can leave residues on sensitive skin if not rinsed. Powder cleansers (enzymes, clay) are interesting for gentle exfoliation but require precise dosing to avoid irritation.

Mistakes to avoid when cleansing your face

The first mistake is using water that is too hot. Heat dilates pores, true, but it also dissolves surface lipids and increases water loss. Lukewarm to cold water is systematically recommended for rinsing. The second mistake is using a washcloth or rough towel. Mechanical friction can damage the skin's surface and irritate sensitive skin. A clean, soft cotton towel, used with gentle patting, is the least aggressive option. Ideally, soft fabric makeup remover pads or a very wet konjac sponge (whose gelatinous texture is non-abrasive). The third mistake is over-cleansing, thinking it will control imperfections or oiliness. Paradoxically, overly frequent or aggressive cleansing can make the skin appear shinier due to rebound. Facial cleansing should not exceed twice a day for most skin types. The fourth mistake is ignoring the neck and jawline, areas where makeup and pollution frequently accumulate and are nevertheless prone to imperfections.

Cleansing methods according to skin type

For oily and blemish-prone skin, a pH 4.5-5.0 cleansing gel with salicylic acid 0.5% or diluted tea tree extract in the evening, followed by a cold water rinse. In the morning, a simple lukewarm water rinse is often sufficient for oily skin that hasn't accumulated impurities overnight. For dry and mature skin, a cleansing milk or makeup remover oil in the evening, a creamy cleanser or simple floral water in the morning. The principle of cleansing oil is particularly suitable: it dissolves impurities while preserving skin comfort, thanks to its affinity for fatty substances. Prickly pear oil, for example, used as a cleansing method, cleanses while providing a feeling of comfort and suppleness. For sensitive and reactive skin, micellar water without rinsing (or with a light cold water rinse) in the morning, an unscented milk or oil in the evening. Never exfoliate, never use water that is too hot.

Pore cleansing: realities and limitations

The idea of "opening pores" then "closing them" with cold water is a persistent myth. Pores do not have sphincter muscles and do not open or close. What changes with heat or cold is the viscosity of sebum and the appearance of the skin, not the anatomical size of the pores. Visible pores are pilosebaceous follicles dilated by excess sebum or a keratinocyte plug (microcomedones). To help refine the appearance of dilated pores, we favor active ingredients known to help mattify the appearance of shiny areas (niacinamide, retinol, salicylic acid) and regular chemical exfoliation, rather than thermal treatments. Hyaluronic acid applied to the surface can help reduce the appearance of pores by improving the skin's hydrated appearance, but it does not change their actual anatomical diameter.

Frequently asked questions about facial cleansing

Should you wash your face in the morning if your skin was clean from the evening?
For dry and sensitive skin, a simple rinse with lukewarm water or a floral water is sufficient in the morning. For oily or combination skin, a gentle cleanser in the morning remains beneficial to remove sebum accumulated overnight.

Are electric cleansers (Foreo, Clarisonic) effective?
They improve mechanical cleansing through ultrasound or vibrations. For normal to oily skin without sensitivity, they can optimize cleansing. For sensitive or redness-prone skin, they should be avoided: their stimulation can accentuate reactivity.

Can you wash your face with Marseille soap?
No, even authentic Marseille soap has a pH of 9-10, which is largely alkaline. It can disrupt the skin's pH and comfort, even if it is of natural origin. The criterion is pH, not origin.

Does mineral makeup require special cleansing?
Mineral pigments (iron oxides, mica, titanium dioxide) are water-insoluble and require an oil-based first step to be completely removed. Double cleansing is recommended for any long-wearing makeup or mineral SPF.

Should micellar water be rinsed off?
Theoretically no, but micelle residues can make sensitive skin uncomfortable. A light cold water rinse after application is advised for reactive skin.

How often for a deep pore cleansing?
A deeper cleanse (clay mask, AHA serum in the evening) once a week is sufficient for most skin types. Beyond that, the risk of irritation and dryness outweighs the benefit.

Is the konjac sponge suitable for sensitive skin?
Yes, it is the gentlest mechanical accessory available. Its moist gelatinous texture cleanses by capillarity without abrasive friction. It should be rinsed after each use and replaced every 4-6 weeks to prevent bacterial proliferation.

Which facial cleanser to choose according to your skin type?

Facial cleansing is the first step in any routine. The right cleanser depends on your skin type and the nature of the impurities to be removed.

• Oily skin: a foaming cleansing gel helps mattify the appearance of shiny areas and unclogs pores without stripping.
• Dry to normal skin: a cleansing oil or makeup remover oil dissolves makeup and impurities while preserving the hydrolipidic film.
• Sensitive skin: a gentle micellar water or cleansing milk respects the skin barrier.

Steps for effective facial cleansing

Successful facial cleansing removes accumulated impurities (pollution, excess sebum, makeup) without harming the epidermis. In the evening, start with a cleansing oil to dissolve makeup, then a facial cleanser adapted to your skin type to gently purify the skin. Finish with an alcohol-free toner that rebalances the skin and refines the appearance of pores. In the morning, a lighter cleanse with micellar water is enough to refresh the complexion.

Whatever your skin type, avoid water that is too hot and harsh cleansers: overly aggressive cleansing weakens the skin barrier and gives the skin a shinier appearance. For normal as well as oily skin, regularity takes precedence over intensity to maintain clear skin and refined-looking pores.
