As summer shifts to autumn, fighting melanin deposits becomes a priority. So, how to save the skin damaged by UV rays in the summer?
When our skin is exposed to ultraviolet light in the summer, melanocytes receive the signal of invasion, and they activate tyrosinase, which is the catalyst that accelerates melanin production.
Under the synergistic action of tyrosinase and oxygen, the tyrosinase in the melanocyte is converted into dopamine, which is then influenced by the tyrosinase and further converted into dopa quinone, and finally formed melanin.
Once melanin is formed, it migrates upward with the metabolism of the epidermis. Over time, melanin gradually emerges on the surface of the skin, causing the skin tone to darken and even form spots. Therefore, autumn is a good time to take measures to reduce melanin deposition.
First, the root cause of skin problems after sun
The root cause of sunburnt skin problems lies in the damage of ultraviolet rays, which is an important factor that can not be ignored in medical cosmetology. Uv rays are divided into two main types, UVA and UVB, which each have different effects on the skin and therefore require different treatments.
UVA UV
This ultraviolet light is able to penetrate deep into the skin and directly affect the dermis, which is the deep tissue of the skin. Long-term exposure to UVA UV rays can trigger problems with skin aging, including but not limited to wrinkles and sagging.
In addition, UVA can also promote pigmentation, leading to the appearance of so-called sunspots, which are uneven patches of color that appear on the skin. These sunspots not only make the skin look uneven, they can also cause uneven skin tone and affect the overall appearance of the skin.
UVB
It mainly acts on the surface of the skin, the stratum corneum. UVB light causes sunburn and redness because it directly damages the cells in the stratum corneum. In addition, UVB can also stimulate the skin to produce melanin, which can cause the skin tone to become darker and lose a healthy glow. A dull complexion can make a person look tired and unhealthy.
For post-sun skin problems, light medical treatment usually needs to consider the different types of ultraviolet light and its different effects on the skin.
For skin aging and pigmentation caused by UVA ultraviolet light, such as photon rejuvenation, ultra-picosecond laser treatment and acids can be used to help skin metabolize melanin and even skin tone.
For sunburn and dullness caused by UVB rays, soothing and restorative skin care products, as well as topical anti-inflammatory treatments, are available.
Two, how to treat
1. Gentle and clean
Gentle cleansing is the first step in repairing post-sun skin, and it paves the way for subsequent skincare routines. It is important to choose the right cleanser for your skin type, as cleansers that are too irritating or contain too many chemicals may further damage sensitive post-sun skin.
Choose a gentle cleanser
Look for cleansers that do not contain strong cleansing ingredients such as sulfates and alcohol. Cleansers or cleansing gels are generally gentler than soaps and foam cleansers and do not strip the skin of its natural moisturizing factors.
Professional facial care equipment
You can choose a professional facial cleanser, such as Haifei Show, which can clean pores while improving the absorption capacity of the skin.
2. Exfoliate
Choose the right exfoliator for your skin type
Exfoliating products come in many forms, including physical exfoliation (such as scrubs) and chemical exfoliation (such as products containing alpha-hydroxy acids, salicylic acids, or fruit acids). It is important to choose the right product for your skin type and needs. Sensitive skin may be better suited to a mild chemical exfoliator, while oily skin may need a stronger physical exfoliator.
Excessive exfoliation can lead to sensitive and dry skin.
Maintain skin moisture balance
After exfoliating, make sure to moisturize promptly to help maintain skin moisture balance.
Exfoliating helps reduce clogged pores and blackheads, leaving skin smoother. It can also help skin care products penetrate the skin better, making them more effective.
3. Mesotherapy/Phototherapy
(1) Mesotherapy
Many skin care products now advertise the ability to penetrate deep into the skin and achieve deep hydration benefits, but the reality may not be so. To look at the propaganda of skin care products rationally, even if the molecules are very small, their penetration ability is limited, mainly limited to the maintenance of the skin surface, and the maintenance effect of the deep skin is relatively weak.
Mesotherapy, also known as "beauty plastic" therapy, uses the method of introduction to locate, layer, and quantitatively deliver nutrients to the dermis of the skin to solve different skin problems. This method can be more targeted to improve skin problems, compared to ordinary skin care products, it may have a more significant effect on deep skin treatment.
Reverse dull skin tone and reduce melanosis
(2) photoelectric therapy
Can significantly improve post-sun spots and skin dullness. These treatments typically use different types of phototherapy devices, such as photon rejuvenation, ultra-picosecond lasers, and so on, combined with specific wavelengths and energies to achieve even skin tone and improved skin quality.
Photon rejuvenation
Photon rejuvenation uses an adjustable light wave plate to target different skin problems by releasing intense pulses of light at multiple wavelengths. It can stimulate the production of collagen, thereby reducing wrinkles, improving the texture of the skin, and brightening the complexion. At present, the M22-AOPT unique filter is often used to treat sunspots, vascular lesions and red blood lines, and can also improve the texture and luster of the skin, helping to reduce sunspots and pigmentation, making the skin look more even.
Laser therapy
Laser therapy helps eliminate spots and pigment problems on the skin, and different types of laser devices are available for different types of spots and skin problems.
4. Skin care routine
Skin care habits are crucial in the process of skin repair and whitening after light medical treatment. Good skin care habits help skin repair and speed up melanin metabolism and delay the formation of wrinkles.
Complete makeup removal:
Make sure to remove all makeup, sunscreen and dirt. Choose gentle makeup removers to avoid rubbing your skin too much.
Eye Care:
Don't neglect eye care and use an eye cream that is suitable for the skin under your eyes to help reduce dark circles, fine lines and swelling.
Moisturizing:
Use products that contain moisturizing ingredients, such as hyaluronic acid or glycerin, to help the skin retain moisture and prevent dryness and dehydration.
Regular cleaning and exfoliation:
Exfoliating and scrubbing steps can be regularly included in your skin care routine to help remove old skin and promote cell regeneration.
