Sunscreen

Sun protection is an important aspect of skin care. Though the sun is beneficial in order for the human body to get its daily dose of vitamin D, unprotected excessive sunlight can cause extreme damage to the skin.
Ultraviolet Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nanometer, nm (with a corresponding frequency around 30 Hertz, PHz) to 400 nm (750 Hertz, THz), shorter than that of visible light, but longer than ...
(UVA and UVB) radiation in the sun's rays can cause sunburn in varying degrees, early ageing and an increased risk of skin cancer. UV exposure can cause patches of uneven skin tone and dry out the skin. It can even reduce skin's elasticity and encourage sagging and wrinkle formation.

can protect the skin from sun damage; sunscreen should be applied at least 20 minutes before exposure and should be re-applied every four hours. Sunscreen should be applied to all areas of the skin that will be exposed to sunlight, and at least a tablespoon (25 ml) should be applied to each limb, the face, chest, and back, to ensure thorough coverage. Many tinted moisturizers, foundations and primers now contain some form of SPF. Sunscreens may come in the form of creams, gels or lotions; their SPF number indicates their effectiveness in protecting the skin from the sun's radiation. There are sunscreens available to suit every skin type; in particular, those with oily skin should choose non-comedogenic sunscreens; those with dry skins should choose sunscreens with moisturizers to help keep skin hydrated, and those with sensitive skin should choose unscented, hypoallergenic sunscreen and spot-test in an inconspicuous place (such as the inside of the elbow or behind the ear) to ensure that it does not irritate the skin.


Elderly

Skin ageing is associated with increased vulnerability. As one ages, so does their skin. Fine lines, bruising, spots, dry skin, and more can slowly, overtime become more apparent. Although wrinkles occur naturally as we age, smoking can worsen the appearance of wrinkles. As humans spend time in the sun, we aren't aware of the long-term effects. As time progresses, sunspots, dryness, wrinkles, or even cancer can occur from sun exposure. This can also occur by tanning either with the sun or with the usage of UV lights. The exposure to UV makes skin less ecstatic. Skin problems including

There is limited evidence that moisturizing soap bar; combinations of water soak, oil soak, and lotion are effective in maintaining the skin integrity of elderly people when compared to standard care.


Acne

According to the American Academy of Dermatology, between 40 and 50 million Americans develop acne each year. Although many associate acne with adolescence, acne can occur at any age, with its causes including heredity, hormones, menstruation, food, and emotional stress. Those with inflammatory acne should exfoliate with caution as the procedure may make conditions worse and consult a dermatologist before treatment. Some anti-acne creams contain drying agents such as

Wound healing

Wound healing is a complex and fragile process in which the skin repairs itself after injury. It is susceptible to interruption or failure that creates non-healing chronic wounds.

Preventive intensive moisturizing with emollient ointments several times, avoidance of water-based creams and water soaks (although in certain circumstances white vinegar or potassium permanganate soaks may help), protection the skin from excessive exposure to sunshine, and soap substitutes which are less dehydrating for the skin than normal soaps, as well as shampoos that reduce the risk of scalp folliculitis, are recommended. Treatment measures with topical antibiotic medication can be helpful.
