1. Normal Aging

The cause of normal aging skin is no other than the natural decline in our bodily functions that we experience when we age.

Our skin loses some of its integrity as we age. This is inevitable, and it will gradually come no matter how much we take care of our skin. As we age, the skin changes in appearance. The epidermis thins and becomes paler. Elder adults have translucent, crepey skin with more visible veins. Biologically aged skin will become increasingly lax, wrinkled, dry, and thin overtime. Biologically aged skin typically will lack blemishes and sunspots and will be textually flat.

2. Photoaging

Photo aging is characterized by early onset of signs of aging caused by frequent exposure to the sun. This damage is not exclusive to sun exposure though. Getting exposed to other UV sources can also add to the skin damage.

Photo aged skin is characterized by a generalized growth and thickening of skin overtime. This is directly opposite of biological aging skin. Patients with this type of skin will have enlarged glands, skin cancers, thickening skin, visible blood vessels, sunspots, deep wrinkling, and other pigmentary changes.

The Characteristics of Photoaging

Both endogenous and exogenous skin aging processes affect the quantity and quality of collagen fibers and elastic fibers in the skin.

Normal aging skin becomes thinner, and the epidermis junctions are flattened, resulting in decreased adhesion between the epidermis and the elastic fibers becomes thinner, and reduce in quantity. The collagen fibers become straight, the structure is loose, proteoglycan decreases, and blood vessels between tissues decrease.

Photoaged skin is mostly thickened and the junction of the epidermis is flat, resulting in decreased adhesion between the epidermis, thicker elastic fibers, and increased numbers; reduced collagen fibers, basophilic changes, increased proteoglycans, and vasodilation of blood vessels.

Ultraviolet rays are the main cause of photo-aging. Ultraviolet rays are classified into wavelengths: near ultraviolet (UVA), far ultraviolet (UVB) and ultra-short ultraviolet (UVC).

The penetration of UV rays into human skin is different. The longer the ultraviolet wavelength, the greater the harm to human skin. UVA rays can pass through the dermis. UVB rays has a certain physiological effect on human skin. A large part of UVB rays is absorbed by the skin epidermis and cannot penetrate into the skin. However, due to its higher energy level, it can cause intense light damage to the skin. The dermal blood vessels in the irradiated area can be expanded. The skin can have redness, blisters and other symptoms. When exposed to the sun for a long time, erythema, inflammation, and skin aging can occur. Severely will cause skin cancer.

How to Treat Photoaging

1. Filling therapy

Filling therapy refers to the method of injecting natural or artificial filling materials into the skin to eliminate wrinkles through supporting action. The ideal injectable filling material should have good histocompatibility, have a certain binding ability with the host tissue and have a proper fluidity, be injected into the skin to achieve a plastic and fixed long-lasting effect.

2. Laser treatment

For the prevention of skin aging, the efficacy of various drugs is unsatisfactory, chemical exfoliation and skin grinding operations are complex, postoperative side effects are greater, and the risk is greater! The application of lasers provides a new technique for improving the appearance of skin aging.

2.1 CO2 Fractional Laser treatment

CO2 fractional laser has the advantages of exact curative effect and quick recovery. For yellow skin, most patients will have obvious pigmentation after treatment, so they need good follow-up skin care. Within 3 weeks after receiving CO2 fractional laser treatment, the stimulated fibroblasts continued to produce new collagen, the skin continued to shrink, and new collagen synthesis increased dermal collagen deposition. Wrinkles disappear and the skin is full and delicate.

IPL treatment with 560nm wavelength, will stimulate the formation of new collagen in the papillary dermis. The tolerability and comprehensive repair effects of skin treatment are also better.

4. AHA Chemical Peeling

Panrylic acid can increase the rate of metabolism of epidermal cells, and open the hair follicles, effectively preventing the pores from obstructing, deep into the dermis of the skin, and can stimulate the proliferation and rearrangement of dermal matrix (hyaluronic acid), acidic mucus polysaccharides, collagen and elastic fibers. The skin becomes firm and elastic, fine lines and wrinkles also decrease. It is a very good way to treat photoaging and acne.

Postoperative Repair of Photoaging

In the macro sense, the treatment of photoaging is specifically anti-aging and wrinkle. Our target tissue is the aged fibrous tissue of the dermis. The skin after above treatment by these methods needs to be repaired.

1. Collagen repair products

The first step in the repair of photoaging is the timely addition of collagen to the skin. Immediately after the skin has been broken (except for acid), type III collagen sprays and gels are immediately sprayed and then Type I collagen masks are applied.

2. Compound polypeptide essence

After completing the first step of repair, the next step is to speed up the growth of collagen fibroblasts in our mesoderm and repair the subtle defects of the epidermis, and use a variety of complex growth factors (aFGF, bFGF, EGF, KGF) to achieve their effects. With collagen as the structural framework that supports the skin, fibroblasts are the makers of these structural frameworks.

3. Repair of epidermis

In the course of repair and treatment against photoaging, our laser treatment will destroy the skin barrier function; the skin's TEWL (transcutaneous moisture loss) will rise significantly at this time, in order to moisturize and accelerate the metabolic rate of the epidermis, we can use moisturizing essence for hydrating and to restore skin barrier function.

How to Prevent from Photoaging?

1. Hold an umbrella and wear a mask

Good sun protection awareness has to be cultivated from a young age. If the child does not have sun protection, their skin will become very bad after growing up, which will further lead to an increase in photoaging. So go out for an umbrella and wear a mask for good physical sun protection is necessary.

2. Active use of sunscreen

The principle of physical sunscreen is the use of reflective particles (the main component is titanium dioxide, the use of reflection or scattering, blocking the ultraviolet rays to achieve the purpose of sun protection.) Adhere to the surface of our skin to block, reflect or scatter ultraviolet light, so that the amount of ultraviolet light reaching the skin Can be reduced to achieve the purpose of sun protection.

Physical sunscreen usually stays on the surface of the skin and does not chemically react, so it is mild to the skin.
