What are the best anti-aging prevention methods in 2025?

By 2025, we know that

are not the only way to combat skin aging. Sleep is also an essential pillar of

, because it is precisely between 11pm and 2am that a fascinating process begins: cellular renewal.

During this cycle, old and damaged cells are replaced by new cells, rich in water, lipids, and pigments, which rise to the surface of the epidermis. This process, which can take between 21 and 28 days to complete, acts as an invisible but constant regeneration. It repairs damage caused by the sun, pollution, or stress , strengthens the skin barrier, and preserves the skin's natural moisture. Thanks to this process, collagen and elastin are supported, elasticity and firmness are maintained, and the complexion gains radiance and evenness.

Thus, sleep is not just a rest for the mind: it is a time when the skin rebuilds itself, nourishes itself and prepares to resist daily aggressions, slowing down time in a subtle and lasting way.

According to a study published in the journal Medical News Today, alcohol is a powerful diuretic that accelerates water elimination by inhibiting the production of vasopressin, an antidiuretic hormone. Its consumption can therefore lead to overall dehydration, resulting in a loss of elasticity and dry skin.

As a vasodilator, alcohol can also cause redness and weaken the skin's capillaries . Furthermore, it can trigger oxidative stress by increasing the production of free radicals, which directly damage collagen and elastin fibers while slowing cell renewal.

We know that cigarettes are a known carcinogen. What is less well known, however, is that smoking is one of the main factors in skin aging because it leads to a

. But that's not the only reason to be wary of it. According to the National Union of Dermatologists-Venereologists, each puff of cigarette smoke releases an average of 200,000 free radicals that attack skin cells.

Studies conducted on cultured cells exposed to tobacco smoke have also demonstrated a notable slowing of the cell renewal process by acting on matrix metalloproteinases, regulatory proteins of renewal.

One might legitimately wonder why hydration and nutrition are considered the cornerstones of anti-aging prevention. Before going into detail, it is essential to distinguish between these two concepts:

Hydration is the process by which the skin receives and retains water , allowing it to remain plump, supple, and elastic.

Nutrition, meanwhile, provides the epidermis with the essential nutrients necessary for its structure and defense , thus strengthening the skin barrier and making it more resistant to daily aggressions.

These two processes are closely linked and, together, help combat skin aging. But why? When the hydrolipidic film is weakened, the skin loses water and its balance is compromised. In this case, moisturizing alone is not enough, because the barrier function is unable to retain water in the skin tissues. The result: the skin becomes dehydrated, loses elasticity, and dehydration lines appear .

The solution is simple: you need to seal in the moisture by applying an oil-based treatment or

. A more occlusive product is used as the final step in the beauty routine. This way, the water remains trapped in the skin, which retains its bounce and hydration.

Using harsh cosmetics can be tempting for quick results, especially when you want to refine skin texture, smooth out imperfections, and fight acne. The problem is that including super-powerful active ingredients can also disrupt the skin's balance, and more specifically, its hydrolipidic barrier . 

This film, composed of sweat, water, mineral salts, ceramides, and lipids, protects the skin from external aggressors (pollution, cold, sun rays). But when it's damaged, it loses its impermeability, leading to dehydration, increased skin sensitivity, an imbalance of the skin's flora, and the premature appearance of signs of aging known as dehydration lines. As you can see, when it comes to skincare, gentleness and balance remain key.

Preventing skin aging also involves protection. Wind, pollution, UV rays, and cold weather can all disrupt the skin barrier. And when the hydrolipidic film is damaged, it can no longer maintain optimal skin hydration against external aggressors. 

This dehydration leads to a loss of elasticity and suppleness, making fine lines more visible . Furthermore, repeated aggressions promote the production of free radicals that degrade collagen and elastin, two proteins essential for maintaining skin firmness and bounce. 

Over time, this combination of factors accelerates skin aging, and wrinkles eventually appear. But how can you protect your skin from external aggressors? The answer is simple: by moisturizing it and maintaining a strong hydrolipidic barrier. But protection also involves using sunscreen every day to limit the harmful effects of UVA and UVB rays on the skin. 

Stress, gut flora imbalance, prolonged pain… Chronic inflammation should not be taken lightly, as it can lead to increased formation of free radicals. These free radicals are responsible for premature skin aging because they damage the DNA of skin cells . 

While this problem is the most common, another, more insidious one can also occur silently: the disruption of cell renewal . This phenomenon can occur when inflammation slows down metabolism and disrupts the function of fibroblasts, which are responsible for the production of collagen and elastin. 

To detect inflammation and its cause, it is in order to find solutions adapted to each situation and to prevent this problem from becoming established.

According to Geroscience, a scientific journal, the seven pillars of anti-aging are inflammation, stem cell regeneration, stress, macromolecular damage, proteostasis, metabolism, and epigenetics.

There are two main causes of premature wrinkles on the face and body:

• Prolonged exposure to sunlight.

  This is one of the main factors responsible for skin aging. While UVB rays can cause sunburn and superficial skin burns, it is UVA rays that are the real enemies of skin health. UVA rays are the main cause of skin cancer and premature skin aging because they penetrate deep into the dermis and cause damage to the DNA of exposed cells.

  Unfortunately, this phenomenon does not diminish when living in an area where clouds are prevalent. In France, it is in Brittany, not Provence, where the rate of skin cancer is highest, according to Ameli.

  As you can see, it is essential to protect yourself from UV rays by exposing yourself moderately with sunscreen suited to your skin type, even on cloudy days.

  
  

• Repetitive movements.

  Repeated facial expressions can cause wrinkles to appear, mainly on the thin and fragile areas of the face such as around the eyes and mouth. However, a study has shown that the area most affected by expression lines in women is the forehead, which is often used to express surprise, astonishment, or joy.
