- UV exposure: Prolonged exposure to the sun's harmful UV rays can increase the production of free radicals and cause oxidative stress.
- Pollution: Exposure to air pollution, smoke, and other environmental toxins can also increase oxidative stress levels in the skin.
- Stress: Psychological stress can trigger oxidative stress and contribute to skin aging.
- Lifestyle choices: Poor diet, lack of sleep, and alcohol consumption can also increase oxidative stress levels in the skin.
- Fine lines and wrinkles: Oxidative stress can cause the skin to lose its elasticity, leading to the formation of fine lines and wrinkles.
- Dull complexion: Oxidative stress can leave the skin looking dull, lifeless, and lack luster.
- Dark spots: Oxidative stress can cause hyperpigmentation and the formation of dark spots on the skin.
- Inflammation signs: Oxidative stress can also trigger inflammation, exacerbating existing skin conditions and leading to further damage.
Impact on the skin
- Premature aging: Oxidative stress can accelerate the skin aging process, leading to a loss of elasticity and the formation of fine lines and wrinkles.
- Weakened barrier function: The skin's barrier function can be weakened by oxidative stress, making it more susceptible to damage from external factors.
- Increased sensitivity: Oxidative stress can make the skin more sensitive, leading to redness, itching, and irritation.
- Loss of radiance: Oxidative stress can leave the skin looking dull and lack luster, taking away its natural radiance and glow.

These two women are twins: one is exposed to the sun and the other is not! Jeanne (left), 61, says her twin sister Susan (right) looks "ten years older"… A scientific study showed that she looked exactly 11 years older than her sister. This is explained by a bad habit of regularly exposing herself to the sun (Susan lives in Florida) while her sister avoids it (she lives in Ohio). We see here the sun spots (which people modestly call "age spots") and the much more marked wrinkles on the twin who abused the sun… The environment (called the "exposome" by scientists) is responsible for 90% of the signs of aging… What if we took care of our skin?
