What is the reason for yellowing of the T-shaped area

The yellowing of the T-shaped area may be caused by factors such as oil oxidation, keratin accumulation, insufficient sun protection, dietary factors, liver and gallbladder diseases, etc. This phenomenon is closely related to skin metabolism, external stimuli, and internal health status, and needs to be judged based on specific manifestations.

1. Oil oxidation

T zone sebaceous gland secretion is vigorous, and the oxidation and yellowing of oil after exposure to air is a common cause. Excessive sebum secretion combines with pollutants in the air, easily forming a yellow oily glow on the nose and forehead. Use mild cleansing products for daily cleaning and avoid using alcohol containing astringent water to stimulate sebaceous glands. Salicylic acid or fruit acid skincare products can help dissolve oxidized oils, but should be used with caution for sensitive skin.

2. Accumulation of keratin

Failure to timely shed old keratin can lead to dull and yellowish skin. The T zone has a thicker stratum corneum, which makes it easier for dead cells to accumulate when metabolism is slow. Use keratin conditioning products containing lactic acid or papain 1-2 times a week, combined with warm towels for wet application to soften keratin. Excessive exfoliation may damage the skin barrier and trigger sensitive reactions.

3. Insufficient sun protection

Ultraviolet rays can accelerate sebum oxidation and stimulate melanin deposition. The T-zone is located in the prominent part of the face and is more susceptible to direct ultraviolet radiation, resulting in photoaging melasma. It is recommended to choose a broad-spectrum sunscreen with SPF30 or above, and reapply every 2-3 hours. Physical sunscreens such as zinc oxide are more friendly to sensitive skin, while chemical sunscreens should be cautious of possible irritants.

4. Dietary factors

Excessive intake of foods rich in carotenoids, such as pumpkin and citrus, may lead to carotenoids, manifested as yellow deposition in the stratum corneum. A high sugar and high-fat diet can exacerbate the degree of sebum oxidation. Appropriately increasing the intake of fresh vegetables and fruits with high vitamin C and vitamin E content, and reducing the intake of fried foods can help improve skin color.

5. Liver and gallbladder diseases

jaundice may occur when bilirubin metabolism is abnormal, which appears early in weak skin areas such as the sclera and T-zone. Be alert to diseases such as hepatitis and bile duct obstruction when accompanied by symptoms such as dark yellow urine and fatigue. In such cases, it is necessary to seek medical attention immediately to check liver function and avoid using whitening products to mask the symptoms.

To improve yellowing in T zone, a complete skin care process needs to be established: use antioxidant essence in the morning for priming, and choose oil control sunscreen products; After cleaning with amino acid at night, use the repair lotion containing nicotinamide to adjust the water oil balance. Apply a moisturizing facial mask containing tranexamic acid or arbutin once a week to avoid the use of powerful bleaching products. Continuous yellowing accompanied by other symptoms should be promptly screened for liver and thyroid function. Maintaining sufficient sleep and regular exercise can promote skin metabolism and reduce the probability of pigment deposition.
