Must see for women after the age of 30! These three changes indicate that aging has begun

When did the fine lines in the mirror secretly climb up to the corners of the eyes? After staying up late and never being able to revive with full health the next day? Don't rush to blame overtime and stress, these signals may be your body reminding you that the metabolic train is starting to slow down. 30 years old is like an invisible watershed, with estrogen levels fluctuating quietly, collagen factories reducing production, and even cell renewal becoming sluggish. But don't panic, read these changing codes, you are at least five years younger than your peers.

1. Aging signals emitted by the skin

1. Loss of collagen

Feeling less elasticity when touching the cheeks? This is not an illusion. Reduce collagen by 1% annually after the age of 25, and the rate of loss doubles directly after the age of 30. Ultraviolet radiation and glycation reactions are the scissor hands of collagen fibers, while dry lines and nasolabial folds are the traces of their criminal activities.

2. The skin's ability to lock water decreases

Do you want to apply more facial mask or card powder? Reduced secretion of sebaceous glands can turn the skin into a leaky basket. A 1% decrease in the moisture content of the stratum corneum can cause fine lines to appear. The sudden appearance of eyebrow wrinkles is actually a cry from the skin for hydration.

3. Increased darkening of color spots

The small sun spots on the cheekbones are connected into patches, which is not a retro freckle makeup. The metabolism rate of melanin slows down, coupled with the cumulative effect of photoaging, making the skin like a memory card filled with pigments, requiring regular cleaning of the cache.

2. Changes in bodily functions

1. Decreased basal metabolic rate

Similarly, eating hotpot, at the age of 20, the weight remained unchanged the next day, but now eating an extra bite can lead to weight gain? After the age of 30, the metabolic rate decreases by 2% -3% every decade, which means consuming about 50 fewer calories per day, equivalent to automatically accumulating 2 kilograms of fat per year.

2. Decreased muscle mass

Does it feel more difficult to carry the same bag? Starting from the age of 30, muscle loss is 0.5-1% per year. If not exercised, 10% of muscle mass may be lost by the age of 50. That's also why many people have changed from an apple shaped body to a pear shaped body without changing their weight.

3. Decreased joint flexibility

The lower dog style in yoga classes is becoming increasingly difficult, not entirely due to a lack of practice. Joint synovial fluid secretion decreases and ligament elasticity decreases, and these changes quietly begin at the age of 30.

III. Changes in the Internal System

1. Estrogen fluctuations

Sudden irregular menstruation is not as simple as high stress. After the age of 30, ovarian function gradually declines, and fluctuations in estrogen levels can make emotions feel like a roller coaster ride, even affecting sleep quality.

2. Changes in gut microbiota

Is eating the same food more likely to cause bloating? The number of beneficial bacteria in the intestine drops sharply after the age of 30, while harmful bacteria take advantage of the opportunity to expand their territory, which is an invisible driving force for skin acne and weakened immunity.

3. Decreased brain memory efficiency

Suddenly forgetting key words at the mouth may not be the fault of staying up late. The hippocampus shrinks by 0.5% annually, and the nerve conduction velocity slows down. That's why when I was young, memorizing words was like taking photos, but now it's like using dial-up internet.

There's no need to worry about these changes, your body is just reminding you to upgrade your maintenance plan. Make sun protection a daily mandatory course, include strength training in your schedule, and eat more rainbow colored foods to feed your gut microbiota. Aging cannot be paused, but we can adjust its playback speed to 0.5 times faster. Starting today, let's compete gently with time.
