The Sun And Ageing Of The Skin

The Sun And Ageing Of The Skin



The Sun and​ Ageing of​ the​ Skin
As the​ body ages,​ the​ appearance and​ characteristics of​ the​ skin alter say looks real ugly . ​
the​ areas of​ skin exposed to​ the​ sunlight’s ultraviolet radiation suffer the​ most damage and​ expectedly age faster . ​
it​ can occur at​ an​ early age in​ people who have spent much time outdoors and​ those who are often badly sunburned,​ particularly those who are fair skinned . ​

The dreaded process is​ known as​ photoageing . ​
it​ is​ attributed to​ a​ combination of​ short wavelength UVB injury to​ the​ epidermis outside layers of​ the​ skin and​ long wavelength UVA to​ the​ dermis middle layers . ​

Again,​ ultraviolet radiation is​ largely to​ blame . ​
the​ continuous and​ profound effects of​ oxidation,​ ionisation and​ genetic changes of​ cellular components including DNA deoxyribonucleic acid Weakens the​ skin’s immune system . ​
Hence,​ aging skin is​ prone to​ skin cancer . ​

Scarring from repeated inflammation due to​ sunburn also acne and​ other skin diseases increases dermal collagen and​ causes the​ dermis to​ lose elasticity . ​
the​ epidermis becomes thinner so the​ skin easily dries up,​ blisters,​ and​ tears . ​
the​ skin is​ weaker than normal and​ feels dry because it​ is​ less able to​ hold water . ​

The ageing changes are particularly apparent on​ the​ face where fine lines and​ wrinkles,​ discolouration and​ textural changes can be noticed at​ closer look or​ in​ serious cases,​ remarkably noticeable . ​

Lingering under the​ sun without adequate protection causes overactivity of​ tanning cells,​ called melanocytes . ​
Consequently,​ ugly sights of​ blotchy pigmentation with brown freckles,​ solar lentigines and​ white marks would appear . ​

Tangled masses of​ damaged elastin protein in​ the​ dermis result to​ yellow thickened bumps elastosis or​ heliosis . ​
Aging skin is​ also very prone to​ develop brown warty lesions seborrhoeic keratoses,​ cherry red spots angiomas,​ dilated small blood vessels telangiectases and​ bruises senile purpura . ​

Tender red dry spots or​ solar keratoses also known as​ actinic keratoses,​ though more common on​ the​ backs of​ the​ hands are also often found on​ the​ temples,​ bridge of​ nose,​ cheeks and​ upper lip . ​

The degree of​ photoageing has been classified by dermatologists as​ Mild age 2835 years Few wrinkles,​ no keratoses; Moderate age 3550 years early wrinkling,​ sallow complexion with early actinic keratoses; Advanced age 5060 years persistent wrinkling,​ discoloration of​ the​ skin with actinic keratoses; and,​ Severe age 6570 years severe wrinkling,​ photoaging,​ gravitational and​ dynamic forces affecting skin,​ actinic keratoses with or​ without skin cancer . ​

To remedy,​ or​ if​ only to​ delay further harm,​ it​ is​ still best to​ completely protect sundamaged skin from more sun exposure . ​
Outdoor activities during the​ middle of​ the​ day,​ especially on​ summer should be avoided . ​
Almost obligatory,​ sunscreens should be applied daily,​ more often when outdoors . ​

Range of​ cosmetic products to​ care for​ ageing skin from simple moisturizers and​ sunscreens to​ retinoid creams and​ Alphahydroxy acids are available in​ the​ market today . ​
a​ dermatologist or​ plastic surgeon is​ still the​ best source for​ expert advice . ​
a​ cosmetic surgeon may suggest clinical treatments that rejuvenate photoaged skin such as​ BOTOX® Cosmetic to​ reduce frowning and​ several resurfacing procedures such as​ dermabrasion,​ chemical peels,​ and​ laser resurfacing remove the​ top layer of​ damaged skin . ​
Cosmetic surgery is​ required to​ remove redundant sagging skin,​ baggy eyelids necessitate blepharoplasty while a​ face lift is​ needed to​ tighten the​ jowls . ​
