What happens to the skin after the age of 70? There are many changes, often underestimated but today at the center of new investigations so much chand we start talking about precision dermatology for aging skin. The main changes are extreme dryness and thinning, persistent itching, new age spots, creases, irritation, inflammation, scaling and allergies. Over the years, skin infections increase and form more easily bruises and rashes, you sweat less and wounds heal more slowly.
The disturbances
With age, the integrity of the skin decreases and affects the quality of life – explain the researchers of Ballarat University, in Australia, in a survey dedicated to skin hydration in over 70s. – The junction between dermis and epidermis is reduces, stiffening the tissue and exposing it to lesions and ulcerations, which in fact affect up to 22% of the elderly. They are poorly investigated, underestimated, but preventable disorders.
Analysis of products and genetics
Australian scholars have conducted an analysis on current remedies and evaluated the use of moisturizing lotions and emollient ingredients, considering them insufficient and hoping for new therapies and remedies. They also speak of a new ad hoc dermatology for octogenarians University of Bristol researchers pointing a curb the biological mechanism of skin aging modulated by genes. Observing over 500,000 British people from the UK BioBank program, they selected the great old men with excellent skin, discovering 75 genes that are significant for slowing down the biological processes underlying skin aging. In the study, published in the Journal of Investigative Dermatology, explain how this could open up the possibility of precision treatments to keep skin healthy over the years.
The American Guidelines
In the meantime, mature skin can be protected and discomfort alleviated by following the guidelines of the American Academy of Dermatology (Aad): to reduce itchy skin in the cold months a ten-minute bath in not too hot water is good; no soap, better a ddelicate, creamy and fragrance-free cleanser; Surfactants are not recommended (avoid using bath cleansing oils as they increase the risk of slipping in the tub or on the shower tray). To alleviate itching and dryness, dermatologists recommend luse of humidifiers in the home because dry air and heating accentuate itching, dehydration, erythema and skin fragility. The humidity in the house should be between 45 and 60%. Late and better avoid perfumes, colognes, creams and cosmetics that contain fragrances because they can irritate fragile skin. Instead, indicated the emulsions that compensate the deficiencies of the hydrolipidic film, with water / oil type formulas, ceramides, cholesterol, fatty acids and hyaluronic acid.
To combat itching
Great polidocanol, also prescribed in case of eczema, and natural rehalba oat extracts against itching explains Emanuele Bartoletti, plastic surgeon and president of the Italian Society of Aesthetic Medicine. For youth errors related to sun exposure, today’s seniors pay the price of increasing skin cancers, such as melanoma and squamous cell carcinoma.
Skin tumors
Researchers from the University of Texas at Houston, in a review of studies published in the journal Jama Dermatology, remind that the phenomenon very underestimated around the world. We are also witnessing a significant increase in actinic keratoses already from the age of 60 – adds Bartoletti -. They are precancerous lesions correlated with the dose of ultraviolet rays received by young people without precaution. THEn increase also senile lentigo, keratosis and angiomas due to UV rays. The great old men must not let their guard down and must protect their skin with high shielding creams. For reduce age spots on the other hand, antioxidant and lightening serums are indicated, based on glycolic and retinoic acid at 0.1% in galenic formulation or at 0.05% in cosmetic products. Urea creams are also useful in percentages between 20 and 30% and depigmenters with kojic acid, azelaic acid and vitamin C. These compounds must be combined with emollient emulsions because they can cause an increase in skin dryness.
Antioxidants and beauty treatments
Among the antioxidants also vitamin C, vitamin E. In addition to extracts of snail slime, ferulic acid and resveratrol. Finally, after the age of 70 there are contraindications to undergo aesthetic treatments, even if done regularly in previous years. Bartoletti explains: The so-called anti-wrinkle “punctures” are no longer suitable, they give unpleasant results. There are dermatological therapies more suitable for giving light and uniformity to the complexion rather than rejuvenating it. on the other hand, it is very useful to follow a diet rich in fresh and seasonal fruit and vegetables, making an effort to drink at least two liters of water a day even if thirst tends to disappear in old age.
