The effects of the sun on skin aging

As the body ages, the appearance and properties of the skin change – for example, “looks really ugly” becomes more common. The parts of the skin that are exposed to the sun’s UV radiation suffer the most damage and, as a result, age faster. The condition can manifest itself at a young age among those who have spent a lot of time outdoors and who are often sunburned, especially those with pale skin.

Photoaging is the term used to describe this unpleasant process. Several factors are implicated, including short-wavelength (UVB) damage to the epidermis (outer skin layers) as well as long-wavelength (UVA) damage to the dermis (inner skin layers) (middle layers).

Once again, UV light is a major contributor to the problem. The ongoing and significant impacts of oxidation, ionization and genetic alterations of biological components, including DNA (deoxyribonucleic acid), on the skin’s immune system, weaken it over time and make it more vulnerable. As a result, aging skin is more susceptible to skin cancer.

Scars caused by recurrent inflammation caused by sunburn (as well as acne and other skin conditions) increase dermal collagen and cause the dermis to lose its flexibility, resulting in wrinkles and fine lines. As the epidermis thins, the skin is more prone to dryness, blistering and tearing. Because it is less able to retain water, the skin is weaker than normal and appears to be dry.

It’s especially obvious on the face, where fine lines and wrinkles, discoloration and texture changes can all be seen – either on closer inspection or, in more extreme situations, with remarkable clarity.

Excessive exposure to the sun without adequate protection promotes hyperactivity of tanning cells, also known as melanocytes, in the skin. This would result in the appearance of unsightly pigmentation patterns such as brown freckles, solar lentigines and white spots on the skin.

Yellow, thickened lumps in the dermis are caused by tangled masses of degraded elastin protein in the dermis (elastosis or heliosis). In addition to brown warty lesions (seborrheic keratoses), cherry-red spots (angiomas), dilated small blood vessels (telangiectases) and bruises, aging skin is also prone to developing other skin conditions (senile purpura).

Red, dry patches, also known as solar keratoses (also known as actinic keratoses), are most often seen on the backs of the hands, although they can also be found on the temples, bridge of the nose, cheekbones and upper lip if they are on the right location.

Dermatologists classified the degree of photoaging into the following categories: Mild (between 28 and 35 years): few wrinkles, no keratoses. The condition is moderate (age 35-50 years) and manifests itself as early wrinkles, dull complexion and actinic keratoses. Advanced (50-60 years): persistent wrinkling, skin discoloration and actinic keratoses; Severe (age 65-70 years): severe wrinkles, photoaging, gravitational and dynamic forces affecting the skin, actinic keratoses with or without skin cancer; e, Severe (age 65-70 years): severe wrinkling, photoaging, gravitational and dynamic forces affecting the skin,

It is preferable to fully protect sun-damaged skin from further sun exposure, even if it is simply to prevent further damage from occurring. Outdoor activities should be avoided during the middle of the day, especially during the summer. Sunscreens should be used at least once a day and more often when spending time outdoors.

There are a wide variety of cosmetic products available on the market today to care for aging skin, from basic moisturizers and sunscreens to retinoid creams and alpha hydroxy acids. Expert guidance from a dermatologist or plastic surgeon is still the best source of information. If you have photoaged skin, a cosmetic surgeon can recommend clinical treatments to rejuvenate it, such as BOTOX® Cosmetic to reduce brow furrowing and various resurfacing procedures to remove the top layer of damaged skin, such as dermabrasion, chemical peels, and skin resurfacing. laser to remove the top layer of damaged skin. Cosmetic surgery is needed to remove superfluous skin sagging, and blepharoplasty is needed to tighten jowls.
