Skin Care For Aging Skin

The process of caring for your skin is very intricate and delicate. As people age, their skin tends to require more effort and care. Aging skin is prone to dryness, wrinkles, sagging and age spots. As such, it is necessary that special care be taken so that aging skin can still look its best. For persons who are aging, the importance of wearing daily sunscreen cannot be stressed enough. Sunscreen serves to protect the skin from wrinkling and from the development of age spots. This not only applies to the face but the entire body, especially the hands. When purchasing cosmetics such as moisturizer and foundation, you should purchase one that includes a sunscreen and that blocks both UVA and UVB rays. The moisturizer or foundation should have a minimum SPF of 15 in order to be effective against the damage that can be done to the skin by sun rays. In addition to the use of sunscreen, persons who are aging should try as best as possible to minimize the time that is spent in the sun since excessive exposure to sun is damaging to the skin. As much as possible, persons who are aging should try to wear long sleeved shirts, long pants and hats when in the sun. It is necessary that attention be paid to the ingredients that are in your skin care products since certain ingredients tend to damage skin. Since aging skin is more prone to damage, then extra care should be taken. Products that include ingredients such as menthol, lime, lavender, fragrances and botanical oils should be used in small amounts if they are used at all. Also, the skin should be moisturized especially in cold weather and dry heat. These environmental factors tend to make skin more susceptible to damage. Wrinkles also appear to look worse when the skin is dry, therefore the skin should remain moisturized. With respect to cleansers, persons with aging skin should make use of alpha-hydroxy cleansers and lotion especially if they have age spots on their skin. These cleansers and lotions aid in the reduction of the appearance of fade spots. In addition to cleansers and moisturizers, it would be wise to use fade creams or cosmetic products that are geared specifically towards reducing the appearance of age spots. With respect to skincare, it would be remiss to not mention the effect that lifestyle plays in the aging process of the skin as well as the appearance of skin. There are certain habits that speed up the process of aging and these should be eliminated as best as possible from one’s lifestyle. Habits such as smoking tend to speed up the process of aging of the skin and it also increases wrinkles and dryness. Cigarette smoke serves to deplete the level of Vitamin C in the body, a vitamin which is essential in keeping the skin looking moist and plump. Lack of exercise, lack of sleep, exposure to cold weather, alcohol consumption and stress also speed up the aging process of skin. Removing these things from your lifestyle would ensure that you would have healthy skin, even as you age.

The relationship between the sun and wrinkles

Many may not be aware, but the sun and wrinkles are closely related with each other and reading further will help you piece together the relationship between the sun and wrinkles. It is a fact that exposure to ultraviolet light, whether UVA or UVB, that is derived from sunlight, accounts for 90% of the symptoms of premature skin aging. Since most of the photoaging effects occur by the age of 20, the amount of damage to the skin caused by the sun is determined by the total lifetime amount of radiation exposure and the pigment protection. Among the changes in the epidermis caused by continued exposure to the sun include, many harmful, thinning of the epidermis and the growth of skin lesions such as actinic keratoses, squamous cell carcinomas and basal cell carcinomas, Prolonged exposure to the sun cause collagen in the dermis to break down at a higher rate than just chronologic aging. Collagen fibers get damaged by sunlight and causes the accumulation of abnormal elastin and when this sun-induced elastin accumulates, enzymes called metalloproteinases are produced in large quantities. Under normal conditions, metalloproteinases are responsible for fixing sun-injured skin by manufacturing and reforming collagen. However, this process does not always work well and some of the metalloproteinases actually break down collagen, resulting to the formation of disorganized collagen fibers known as solar scars. And when the skin repeats this flawed rebuilding process, wrinkles develop. As the sun continues to be the principal suspect in causing wrinkles, the most important skin-care product available to prevent wrinkles is sunscreen, but most people do not use sunscreen correctly. It would be best to consider the important factors with sunscreen use, especially with the spectrum of UV radiation absorbed, the amount of sunscreen applied, and the frequency of application. As mentioned earlier, the sun gives off ultraviolet (UV) rays that can be divided into categories based on the wavelength. UVC radiation is absorbed by the atmosphere and does not cause skin damage, while UVB radiation affects the outer layer of skin, the epidermis, and is the primary agent responsible for sunburns. UVB does not penetrate glass and the intensity of UVB radiation depends on the time of day and season. UVA radiation, on the other hand, penetrates deep into the skin and works more efficiently and cannot also be filtered by glass, but overexposure to UVA can also be dangerous. The intensity of UVA radiation is more constant than UVB without the variations during the day and throughout the year. Regardless of their wavelengths, both UVA and UVB radiation can cause wrinkles as it breaks down collagen, creating free radicals, and inhibiting natural repair mechanisms of the skin. A classification system of sun-sensitivity is the Skin Phototype (SPT) classification, which is being used to determine the potency and spectrum of protection that sunscreen formulations help protect from these radiation, as well as inhibit, if not minimize, wrinkles. People with skin types I and II are at the highest risk for photoaging effects including wrinkles and skin cancer, thus the proper use of sunscreen to block both UVA and UVB radiation is an important in the battle against wrinkles. As promised, the relationship between the sun and wrinkles has been established and the age old agae still holds true that says, an ounchttp://skin-care.hot-trend-now.com/category/wrinkles-2/e of prevention is better than a pound of cure.

The Role of the Sun in Skin Care

Many people believe that the sun is a good contributor to ensuring good skin, but always be wary that the role of the sun in skin care can only be limited in ways that it actually can do more harm than good when one is not guided accordingly. Vitamin D from the sun can be helpful for many, but it can only be left to that since we all know that we actually need to protect our skin from the sun’s harmful rays, especially from prolonged ultraviolet radiation. Here are some tips to make good use of sun exposure and avoid the dangers of getting too much of it. Always make it a point to wear sunscreen formulated with a sun protection factor (SPF) of no less than 15, regardless if the weather is cloudy or not wanting to spend a lot of time outdoors, since this will help keep your body filter out ultraviolet rays that can be reflected on the earths surface. Make sure to also reapply sunscreen every 2 to 3 hours if you plan to go swimming or get involved in sports activities. Same goes even for sunscreen that is labeled waterproof. It is always better to be safe than sorry. Also look for sunscreen that blocks both UVA and UVB rays, especially those labeled with broad spectrum protection or UVA protection for formulation with an SPF of 15 or greater. Select a sunscreen that is labeled nonacnegenic or noncomedogenic to help keep pores clear and also prevents the skin from having pimples or acne. If possible, stay away from the sun between 10:00 AM and 4:00 PM, which are the times of the day when the sun happens to be the hottest. If staying indoors is unavoidable during these times, make sure to reapply sunscreen frequently and take indoor breaks every so often if you can. One good tip in knowing when it is safer to be under the sun is when your shadow is longer than you are tall, but continue to wear sunscreen just to be safe. Take note to apply more sunscreen with higher SPF when around reflective surfaces like ice, snow or water, since it intensifies the heat, as well as the ultraviolet radiation of the sun. Some medications, like prescription acne treatments or birth control pills can increase a persons sensitivity to the sun, so make sure to ask your doctor if you are taking any or both of these treatments, as well as increasing the SPF of the sunscreen to use when exposed to the sun. If you want the glow of a tan, try to fake it with self-tanners or salon tanning treatments to avoid the risk of getting harmful ultraviolet radiation. You may also want to avoid tanning beds, although manufacturers claim that tanning beds are free of UVB rays, they still use ultraviolet radiation that could also be harmful to the skin. Never ever consider applying sunscreen on your exposed skin to be wasteful, since the cost of getting skin disease costs much more than several tubes of sunscreen. Always make sure to give careful attention to children and do not hesitate to apply sunscreen on them, even double the frequency as you do on yourself. Children have more sensitive skin than adults and need it more than we do. To avoid the risk of getting over exposed you may resort to going on a healthy diet that includes vitamin supplements, especially vitamin D and can be sourced from foods like dairy products, fish, oysters or fortified cereals. Lastly, make sure to always go to a dermatologist whenever you feel something wrong in your skin, since skin cancer is very treatable when discovered early.
