Wrinkles and fine lines: how to diminish them?

Wrinkles and fine lines: how to diminish them?

Wrinkles and fine lines are the result of natural factors, related to the biological aging of the skin. However, certain external factors can promote their early onset. Here are some simple actions to limit their appearance, and reduce their visibility once they have formed.

What is the mechanism behind the appearance of wrinkles and fine lines?

As we age, numerous factors impact the various tissues, resulting in a less smooth, more fragile appearance. Cellular renewal slows down, which reduces the skin's tone and radiant appearance. The sebaceous glands also become less active, leading to skin dryness and a decrease in barrier function. Consequently, the epidermis becomes more vulnerable and sensitive.

Collagen and elastin, which are present in the dermis to support the skin and provide it with elasticity, begin to decrease from the age of 25 - 30 years.

  • The production of elastin by fibroblasts ceases at puberty. Even though elastin proteins are resilient and hard to degrade, certain enzymes called elastases, also secreted by fibroblasts, are capable of cleaving them and making them less effective. The skin then loses its elasticity and wrinkles deepen.

  • As the years pass, collagen synthesis slows down. This loss can begin around the age of 25, and the body can lose approximately 1% of collagen per year, and gradually up to 25% per year. Thus, by the age of 80, we have lost 75% of collagen compared to young adults. Moreover, over the years, collagen fibers become rigid, fragmented, and disorganized.

In addition to this, there is a stock of hyaluronic acid, a sugar naturally present in the skin that ensures its hydration, which decreases by 50% at the age of 50. Consequently, the skin becomes less plump and less hydrated.

It is the accumulation of these skin weaknesses that creates folds on the surface of the skin, known as wrinkles and fine lines.

What are the factors that accelerate skin aging?

  • A prolonged and repeated exposure to the sun contributes to the aging of skin cells, just as tobacco use and pollution do. Fine lines are the first consequences;

  • The stress and the lack of sleep can also contribute to skin aging;

  • The lack of hydration, it is recommended to drink 1.5 L per day which is approximately 8 glasses of water.

What are the good habits to adopt?

The answer appears to lie, quite logically, in a healthy lifestyle:

  • Maintaining a balanced diet;

  • Do not smoke;

  • Regularly drink water to hydrate yourself (at least 1.5 L per day);

  • Engaging in regular physical activity is also recommended to promote blood circulation;

  • Avoid sun exposure or at least always protect the skin with an SPF care product suitable for one's phototype;

  • Finally, quality sleep proves to be very important in the process of cellular recovery.

We also recommend that you hydrate daily with skincare products tailored to your skin type. You can also use targeted treatments for areas that need special attention such as the eye contour or lips.

There are also cosmetic active ingredients available to reduce the appearance of wrinkles and fine lines:

  • Thehyaluronic acid, thanks to its hydrating action, plumps and saturates the skin with water. The skin then regains its suppleness.

  • The antioxidant action of the vitamin C can be beneficial in combating skin aging. It helps to neutralize free radicals, thereby boosting the activity of skin cells.

  • Theglycolic acid or thelactic acid (A.H.A.) help to remove dead skin cells. Therefore, they stimulate cellular renewal.

  • The retinol is also well-known for reducing the appearance of wrinkles and fine lines by stimulating the production of collagen and elastin, two structural proteins. As a reminder, the levels of these two components tend to decrease with age.
