How to choose and use a face wash
Cleansing is the simplest step in a routine, and the one where most mistakes happen. A good facial cleanser removes dirt, excess oil and sunscreen without stripping away the skin's own oils. If your skin feels tight or "squeaky clean" after washing, the product is too harsh.

What does a face wash do?
Throughout the day the surface of your skin collects its own oil (sebum), dead cells, sweat, dust, pollution particles, makeup and sunscreen. If these are not removed, pores can clog and the serums and creams you apply next spread less easily.
The surfactants in cleansers lift oil and dirt off the surface so they rinse away with water. The problem is that harsh surfactants also strip the lipids that make up the skin barrier. So a good cleanser needs to be effective but gentle.
Soap vs face wash
Traditional bar soaps are alkaline, usually with a pH around 9–10. The skin's surface, by contrast, is slightly acidic (about 4.5–5.5). Washing often with alkaline products disrupts this balance and can cause dryness, tightness and sensitivity.
Most dermocosmetic cleansers are based on "syndets" (synthetic detergents) and have a pH close to the skin's own. The words "soap-free" on the label are an easy way to spot them.
Choosing a cleanser for your skin type
- Oily and acne-prone skin: gel or foam cleansers; cleansers with 0.5–2% salicylic acid can help with breakouts
- Combination skin: gentle gel cleansers that do not tighten the drier areas
- Dry skin: cream, milk or oil-based cleansers containing glycerin, ceramides or panthenol
- Sensitive skin and rosacea: fragrance-free products with no essential oils and a short ingredient list
- If you wear makeup or water-resistant sunscreen: in the evening, use a cleansing oil or micellar water first, then your cleanser
What to look for when buying
- The words "soap-free" or "syndet" and a skin-friendly pH
- No fragrance (parfum) or essential oils if your skin is sensitive
- For dry skin, no harsh surfactants such as sodium lauryl sulfate (SLS) near the top of the ingredient list
- No tightness after cleansing, even for oily skin
- Salicylic acid or zinc options for breakouts; use them once a day if they dry you out
How to use it
Wet your face with lukewarm water, lather a hazelnut-sized amount in your palm and massage it in with your fingertips in circular motions for about 30–60 seconds. Rinse with plenty of lukewarm water and pat dry with a soft towel; do not rub.
Never skip the evening cleanse, as that is the only way to remove the sunscreen and grime of the day. In the morning, rinsing with water alone can be enough for dry or sensitive skin; oily skin can use a cleanser in the morning too.
Applying serum or moisturizer within a minute of cleansing, while the skin is still damp, helps lock moisture in.
Common mistakes
- Washing three or four times a day because of breakouts: the drier the skin gets, the more oil it may produce
- Using very hot water: it increases redness and dryness
- Scrubbing every day with harsh grainy products or brushes
- Leaving the cleanser on for a few seconds and rinsing it straight off
- Trying to remove makeup and water-resistant sunscreen with a single cleanser
FAQ
Should I use a cleanser in the morning too?
For oily skin, yes, a light cleanser in the morning works well. For dry and sensitive skin, rinsing with lukewarm water is often enough in the morning.
Does a foaming cleanser clean better?
No. The amount of foam does not reflect cleansing power; some gentle cleansers barely foam but still work well. What matters is that your skin does not feel tight afterwards.
Can I use a salicylic acid cleanser every day?
Most oily skin can use it once a day. If you notice dryness or stinging, switch to every other day. Because a cleanser is only in contact with the skin briefly, its effect is milder than a leave-on product.
Can a face wash remove makeup?
It can remove light makeup. For mascara, long-wear foundation and water-resistant sunscreen, it works better to use micellar water or a cleansing oil first and then wash with your cleanser.
