How to "save yourself" for sensitive skin that can't bear the damage

Let's follow Li Feng, a dermatologist at Peking Union Medical College

Let’s learn scientific skin care methods together:

If your skin has the following symptoms, such as itching, burning, flushing, swelling, dryness, scaling, oil overflow and red blood streaks, it means that there is a problem with your skin barrier.

In order to repair the damaged skin barrier, we must start by understanding the skin’s natural repair period.

# What is the 28-day natural repair period? #

First of all, our skin is composed of three parts: epidermis, dermis, and subcutaneous tissue. The structure of the epidermis is divided into four layers from the inside to the outside: basal layer, spinous layer, granular layer, and stratum corneum. The 28-day natural repair period of the skin is the process of skin cells gradually moving and renewing from the basal layer to the stratum corneum.

This process occurs naturally, and the specific repair process is roughly as follows:

First, the repair starts from the basal layer of the skin. The basal cells divide to produce new epidermal cells. The new epidermal cells continue to move to the outer layer to the granular layer. This process takes about 14 days. Then they enter the stratum corneum and finally fall off on the surface of the stratum corneum. This process takes another 14 days, for a total of about 28 days.

However, we cannot generalize the skin's repair cycle, as it is also affected by many factors, such as strong sunlight, unclean environment, age, physical condition, etc.

So how to make good use of these 28 days of skin self-healing? You need to listen to the scientific advice of dermatologists.

# How to effectively manage your skin in 28 days? #

Dermatologists recommend that during these 28 days you should:

The first is to reduce cleaning, mainly to protect our "brick wall structure", especially the "cement" in our brick wall - the sebum membrane from being damaged.

The sebum membrane is a protective film formed on the skin surface by the oil secreted by the sebaceous glands, the lipids produced by the keratinocytes and sweat. It is the most important layer for the skin to lock in moisture, which can effectively lock in moisture and prevent excessive evaporation of skin moisture. At the same time, it can prevent a large amount of external substances from penetrating and keep the skin healthy.

Second, reduce the types of skin care products, focus on moisturizing and moisturizing, and reduce possible irritants or allergens such as exfoliants, spices, alcohol, and preservatives.

Third, fully moisturize to maintain normal moisture content of the skin, protect the skin barrier, avoid overreaction of the skin to the external environment, and also moisturize the skin.

Fourth, avoid invasive medical cosmetic treatments, stabilize the skin’s internal environment, avoid new inflammation or microcirculation disorders, and give full play to the skin’s self-repair function.

Fifth, get regular sleep, keep a good mood, and relax. A stable neuroendocrine system can better secrete hormones that are beneficial to the skin. This is a way to improve your skin without spending money, and everyone can do it.

Sixth, scientific sun protection can resist the damage of ultraviolet rays to the skin and avoid "thermal aging" of the skin.

* Take sunshade measures:

When going out, you should hold an umbrella and wear protective clothing, such as long sleeves, shirts, wide-brimmed hats, etc. Tightly woven, old, wide or dark-colored textiles are more effective in protecting against outdoor ultraviolet rays. Of course, the simplest way is to find shade, as the SPF value of leaves is equivalent to 4 to 50.

* Apply sunscreen:

Most people apply sunscreen too thinly, so the "actual SPF" is about half of the label value. Broad-spectrum sunscreen with SPF 30 or higher should be applied routinely, especially in areas with high sunlight levels. It should be applied 20 to 30 minutes before sun exposure to form a protective film on the skin, and reapplied within 30 minutes after sun exposure to enhance the sun protection effect. It is recommended to reapply every 2 hours if you are outdoors.
