空氣污染、飲食不當、熬夜、抽菸、酗酒等，都是加速老化的腳步。生活中吃的、吸的、連陽光下的紫外線 ( UVA及UVB）都會促使身體製造過多的自由基，導致皮膚提早衰老，讓皺紋出現，皮膚免疫能力下降，更有可能引致皮膚癌。而這些自由基一旦進入新陳代謝的循環中，就會去攻擊鄰近細胞並迫害好的細胞，引起細胞死亡所以說，自由基是老化的主要元兇。
Air pollution, poor diet, staying up late, smoking, and excessive alcohol consumption are all factors that accelerate the aging process.
In daily life, everything we eat, breathe, and even the ultraviolet rays (UVA and UVB) from sunlight can stimulate the body to produce excessive amounts of free radicals.
These free radicals lead to premature skin aging, causing wrinkles, reducing the skin’s immune defenses, and even increasing the risk of skin cancer.
Once free radicals enter the body’s metabolic cycle, they attack neighboring cells and damage healthy cells, leading to cell death.
Thus, free radicals are considered the primary culprits of aging.
除了自由基之外，體內發炎、荷爾蒙失調（包括生長荷爾蒙、退黑激素、甲狀腺素、腎上腺分泌的 DHEA 、性荷爾蒙）、基因損傷、膠原蛋白流失等等，也都是造成老化的因素。
In addition to free radicals, chronic inflammation, hormonal imbalances (including growth hormone, melatonin, thyroid hormones, DHEA secreted by the adrenal glands, and sex hormones), genetic damage, and collagen loss are also major contributing factors to aging.
