Skin aging is an inevitable process, but did you know that it is possible to slow down its progression with simple steps and wise choices? Hydration, sun protection, and a balanced diet are just a few of the strategies for maintaining youthful, radiant skin. Explore these five essential science-backed tips to understand how to care for your skin on a daily basis.

1. Hydration: a fundamental basis

Drink enough water
An adult loses approximately 2.5 liters of water daily (through urine, sweat, breathing, and bowel movements). To compensate, it is recommended to drink at least minus 1.5 liters of liquid per day, not forgetting the water provided by food (fruit, vegetables, soups, etc.).

Moisturize the skin from the outside
The skin naturally loses some of its water (insensible water loss, or IWL). Apply creams or serums enriched with hyaluronic acid helps retain this water and limits the appearance of fine lines.

2. Sun protection: a barrier against the weather

UVA and UVB rays: real enemies
The sun is responsible for approximately 80 % of premature skin aging. UVA rays, which can penetrate deep into the dermis, damage collagen and elastin fibers, causing skin sagging.

Adopt daily protection
To protect your skin, apply a broad spectrum sunscreen every day, even when it's cloudy. Supplement with skincare products containing antioxidants (vitamin C, retinol, resveratrol) that neutralize free radicals caused by UV exposure.

3. A healthy diet: your best beauty asset

Foods that protect
A diet rich in fruits, vegetables, nuts, green tea and olive oil contributes to the skin's radiance. These foods are packed with’antioxidants which combat oxidative stress, responsible for cellular aging.

Pitfalls to avoid
Conversely, an excess of sugarof red meat or’alcohol can accelerate the appearance of wrinkles via glycation, a process that stiffens collagen and elastin fibers, impairing skin elasticity.

4. Avoid imbalances: quit smoking

The effects of tobacco on the skin
Nicotine and other chemical compounds in cigarette smoke damage the skin's elastic fibers. Tobacco dries out the epidermis, destroys collagen, and causes a dull complexion.

The benefits of stopping
Quitting smoking can significantly improve texture and the color skin in a few months, while slowing down the aging process.

5. Intrinsic aging: understanding the mechanisms

Oxidative stress
Free radicals destabilize skin cells and promote premature aging. A healthy lifestyle, combined with care rich in antioxidants, can mitigate these harmful effects.

Hormonal changes
With age, the decline in certain hormones (estrogen, DHEA, etc.) can lead to decrease skin elasticity and collagen production. Consulting a healthcare professional (dermatologist, endocrinologist) can help you better manage these changes.

In a nutshell, adopting a healthy lifestyle, protecting your skin from the sun, eating a diet rich in antioxidants, and avoiding tobacco are fundamentals to slow down the appearance of signs of aging. Every step counts in preserving radiant, healthy skin.
