Why do you become a yellow faced woman as you get older

Dark yellow skin is a common phenomenon after aging, mainly related to factors such as collagen loss, slowed metabolism, and melanin deposition. During the aging process, the skin's ability to self repair decreases, the stratum corneum thickens, sebum oxidizes, and photoaging accumulates, collectively leading to dull and yellowish skin tone.

1. Collagen loss

The core cause of skin sagging and yellowing is the rupture and atrophy of collagen fibers and elastic fibers in the dermis. After the age of 25, the amount of collagen synthesis in the human body decreases annually, and by the age of 40, skin thickness can decrease by 20%. Suggest supplementing with vitamin C, moderate massage to stimulate collagen regeneration, and using skincare products containing retinol to slow down the rate of loss.

2. Metabolic slowdown

The cell renewal cycle has been extended from 28 days in youth to over 50 days, and the accumulation of old dead skin cells has reduced skin translucency. Gentle exfoliation can improve this problem, but excessive cleaning should be avoided to damage the barrier. Regular exercise can increase basal metabolic rate and promote epidermal cell regeneration.

III. Melanin deposition

Long term exposure to ultraviolet radiation induces an increase in tyrosinase activity, a decrease in melanin metabolism ability, and the formation of stubborn melasma. In addition to strict sun protection, skincare products containing niacinamide can block melanin transport, and ingredients such as arbutin can inhibit tyrosinase activity.

Fourth, glycation reaction

Genuine collagen binds with carbohydrate molecules to produce advanced glycation end products, which can cause the skin to appear caramel colored. Controlling blood sugar levels, reducing high sugar diet intake, and supplementing with anti glycation ingredients such as alpha lipoic acid can help alleviate this phenomenon.

V. Microcirculatory disorders

The decrease in capillary network density leads to insufficient oxygen supply to the skin, and the decrease in hemoglobin oxygen content causes yellowing of the skin color. Alternating cold and hot care, facial scraping can improve local blood circulation, and dark fruits and vegetables rich in anthocyanins can enhance vascular elasticity.

To prevent skin dullness, a systematic maintenance plan needs to be established. Use sunscreen above SPF30 every day, choose antioxidant skin care products containing vitamin E and coenzyme Q10, and replenish water facial mask 2-3 times a week. In terms of diet, consume more foods rich in lycopene and anthocyanins such as tomatoes and blueberries, and supplement collagen peptides in moderation. Ensure 7 hours of deep sleep to avoid exacerbating free radical damage caused by staying up late. If there is a sudden worsening of skin color change, it is necessary to investigate internal medicine issues such as liver and gallbladder diseases. Although aging is irreversible, scientific care can significantly delay the process of skin yellowing.
