In brief
Dry skin lacks lipids, not just water. An effective routine boils down to three principles: cleanse without stripping using a gentle product and lukewarm water, hydrate in the morning with a fluid texture, and nourish at night with a product rich in fatty substances. Apply skincare to skin that is still slightly damp, limit exfoliation to once a week, and allow for three to four weeks of consistency before judging the results, which is the time required for cell renewal.
Dry skin has the particularity of reminding you of its presence several times a day: after a shower, when stepping out into the cold, or at the end of the day when makeup starts to look patchy. It is not an inevitability, but it does require one thing that lengthy routines often overlook: consistency, and the right type of care at the right time.
If you have read our article on skin types and identified yours as dry, this article provides what comes next: what is actually happening within your epidermis, the routine to put in place morning and night, and the daily habits that, without you knowing it, perpetuate dryness.

What exactly is dry skin?
Dry skin produces very little sebum. This sebum, combined with the ceramides and fatty acids present between cells, forms the hydrolipidic film: an invisible layer that retains water inside the epidermis and blocks external aggressions.
When this film is insufficient, water evaporates continuously; this is what is called transepidermal water loss. The skin then becomes permanently dehydrated, not because it lacks water to begin with, but because it cannot manage to keep it. This explains why applying only hydrating treatments to dry skin provides relief for a few hours but then leaves the tightness to return: it is like trying to fill a leaky container.
The entire logic of the following routine is contained in this sentence: repair the barrier before hydrating, and do both together.
Dry skin or dehydrated skin: how to tell the difference?
This is the most costly confusion leading to unsuitable products. The two situations cause similar sensations but are not treated the same way.

The simplest test: dry skin is dry all year round, on both the face and body, and has been since always. Dehydrated skin has become so following a winter, a summer, a change of product, or a period of fatigue. And nothing prevents you from being both at the same time: this is actually the most common case in winter.

Why is your skin dry?
Some causes are constitutional, while others stem from habits that can be adjusted starting today.
-
Genetics: the number and activity of your sebaceous glands are largely hereditary.
-
Age: sebum production and ceramide synthesis gradually decrease from the age of thirty, and even more significantly after menopause.
-
Climate and heating: cold, wind, and heated air accelerate evaporation. Paradoxically, indoors in winter is more drying than being outdoors.
-
Hard water and hot water: they dissolve the hydrolipidic film. This is the primary cause of tightness after a shower.
-
Overly harsh cleansers: abundant foam and a "squeaky clean" sensation are warning signals, not signs of cleanliness.
-
Excessive exfoliation: frequent scrubs or daily acids maintain a state of permanent fragility.

The dry skin face routine, step by step
Three steps in the morning, three at night. At BIOLYSTERE, our products are formulated and manufactured in the south of France, 99% naturally derived, vegan, paraben-free, and dermatologically tested—a standard that counts all the more for skin whose barrier is already weakened.
In the morning: hydrate and protect
Start with a simple rinse with lukewarm water, or a gentle cleanser if your skin sweated during the night. For dry skin, morning cleansing can often be lightened: the night does not soil the face.
Then apply L’Hydratante on skin that is still slightly damp. This detail is not trivial: the residual water is captured by the skincare and trapped under the texture, which significantly improves comfort in the following hours. Help it penetrate using gentle pressing motions with your palms rather than rubbing, and do not forget the neck or the eye contour, two areas lacking or poor in sebaceous glands.
Finish with sun protection as soon as you go outside: UV rays degrade the lipids in the skin barrier, including in winter and on cloudy days.
In the evening: cleanse gently and nourish
Makeup removal is the most delicate step for dry skin. Favor an oily or milky texture, which dissolves makeup and pollution particles without emulsifying your skin's own lipids. Rinse with lukewarm water and dry by patting.
Then apply La Nourrissante, which is richer and designed to rebuild what the day has depleted. Night is the most favorable window: cell renewal intensifies, water loss reaches its peak, and the skin thus gains maximum benefit from an occlusive treatment.
L’Hydratante in the morning and La Nourrissante in the evening make up the foundation duo for dry skin. They are brought together in the L’Essentielle range, designed exactly for this complementary use.
Once a week: exfoliate sparingly
Dry skin accumulates dead cells that make it rough and dull the complexion. A weekly gentle scrub is enough to restore radiance; beyond that, you will damage a barrier that is already insufficient. Always follow it immediately with a nourishing treatment, never the other way around.

Natural ingredients that truly repair dry skin
Not all oils are created equal: some nourish deeply, while others only soften the surface. Here are the ones we rely on, and what they provide.

One principle for building your routine: always combine a hydrating agent, which provides water, with a fatty substance, which retains it. One without the other will never last the day.
The 6 habits that unknowingly worsen dryness
-
Very hot and prolonged showers: they provide immediate relief and dissolve the protective film. Keep it lukewarm and brief, always.
-
Drying by rubbing: friction irritates skin that is already fragile. Pat dry.
-
Waiting until you are dry to apply your cream: the optimal window is within the three minutes after rinsing.
-
Multiplying products: dry skin needs few products, but ones that are well-chosen and applied every day.
-
Changing creams every two weeks: no formula can prove itself in less than one cell renewal cycle.
-
Neglecting the environment: an interior heated to 22°C without humidification dries out the air, and therefore the skin. A bowl of water on the radiator is often enough.
How long until you see results?
Comfort often returns within the first few days: this is the immediate effect of surface hydration. The repair of the skin barrier, however, requires more time. Allow for about twenty-eight days, the average length of an adult's cell renewal cycle, and a little more after age forty.
Specifically: feelings of tightness space out in the first week, roughness fades around the third, and the complexion's radiance returns by the end of the first month. If nothing has changed after six weeks of a regular routine, it is not the cream you should change first, but the cleanser: it is almost always the culprit.
Adapting your routine throughout the seasons
Dry skin stays dry all year, but its degree of discomfort varies. In winter, switch to La Nourrissante morning and night if tightness persists, and space out scrubs. In spring, return to the classic duo. In summer, lighten the morning texture and concentrate the nourishing application on the evening, as the skin is naturally better hydrated by ambient humidity, without forgetting that the sun continues to damage the barrier.

Frequently asked questions
Can dry skin become normal?
Skin type does not change, but an adapted routine makes almost all symptoms disappear: no more tightness, no more roughness, an even complexion. Your skin will still be a low producer of sebum; it will simply stop suffering from it.
Should you use an oil or a cream on dry skin?
A cream, primarily. An oil alone nourishes but does not provide water: on very dry skin, it can give a deceptive feeling of comfort without correcting the underlying dehydration. Ideally, use oil as a supplement, applied over the cream in the evening to seal in the treatment.
Can you have dry skin and imperfections?
Yes, it is more common than people think. A weakened skin barrier lets irritants pass through more easily, which causes inflammatory reactions that look like pimples. The answer is not to dry it out further, but to repair it.
Is night cream really essential?
For dry skin, this is the treatment that makes the biggest difference. Water loss peaks during the night, the time when the skin repairs itself most actively. If you were only to keep one product, it should be this one.
How do I know if my cleanser is too aggressive?
One sign is enough: if your skin feels tight or "squeaky" in the minutes following rinsing, even before applying a treatment, the cleanser is to blame. Properly cleaned skin is supple and comfortable, never squeaky.
In summary
Repairing dry skin long-term does not require ten products or a spectacular routine. Cleansing without stripping, hydrating in the morning, nourishing at night, applying to damp skin, and sticking with it for a month: these five steps are enough to rebuild a functional hydrolipidic film.
The rest—the radiance, the suppleness, and the comfort that no longer calls itself to your attention—comes on its own, and it comes quickly.
