How To Repair Wrinkles and Damage Caused by Sun Exposure
You & your family must have Sun protection. Wrinkles, premature ageing and painful, unsightly skin damage from the Sun can be avoided with the right know-how.
Aging Effects of the Sun and Wrinkles.
Exposure to ultraviolet light, UVA or UVB, from the Sun accounts for over 85% of the symptoms of premature skin aging. 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 person's pigment protection.
To prevent this damage happening in the first place protect yourself with sunscreen containing the proper ingredients, apply it properly. Also, wear UV-protective clothing, designed to protect you.
Primary Repair Treatments.
The primary repair treatments available to reduce the appearance of wrinkles are Alpha Hydroxy Acids (AHA) and Beta Hydroxy Acid (BHA). With increasing research into what causes wrinkles and the effects of photoaging (exposure to sunlight) these repair tools have increased greatly in popularity. They're a very common additive to numerous skin care products including cleansers, moisturizers, masks, toners, and other products.
Alpha Hydroxy Acids
Remember Cleopatra? AHA's have been used for thousands of years as a skin rejuvenating product. She is reported to have bathed in sour mild milk (lactic acid) to improve her already beautiful complexion.
These acids are derived from milk and fruit sugars. The most commonly used sources are lactic acid and glycolic acid because they have a special ability to penetrate the skin. They also have the most scientific data on their effectiveness and side effects.
How Alpha Hydroxy Acids Work.
AHA's work mainly as an exfoliant, allowing the dead skin cells to be removed, making room for regrowth of new skin.
Beta Hydroxy Acids.
There is only one Beta Hydroxy Acid - Salicylic Acid. BHA also works mainly as an exfoliant. Research indicates that Beta hydroxy acid found in skin-care products works best in at a pH of 3 to 4 and a concentration of 1% to 2%.
What's the Difference Between the Two Types?
The main difference is their lipid (oil) solubility. Alphas are water soluble only, while Beta acid is lipid (oil) soluble. This means that Beta hydroxy acid is able to penetrate into the pore which contains sebum and exfoliate the dead skin cells there too.
Because of this difference in properties, Beta hydroxy acid is better used on oily skin with blackheads and whiteheads. Alphas are better used on thickened, sun-damaged skin where breakouts are not a problem.
Side Effects
The two major side effects of Alphas and Betas are irritation and sun sensitivity. Consult your dermatologist.
It's essential that anyone using any Alpha or Beta hydroxy acid must use a good sunscreen that contains UVA and UVB protection.

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 ounce of prevention is better than a pound of cure.

Buy Wrinkle Cream and Practice These Four Healthy Skin Habits
Wrinkles are inevitable. As we age, our skin will form wrinkles. Because of this, we buy wrinkle cream. It helps prevent more wrinkles and lessens the appearance of the ones we already have, but it is not enough to keep those pesky wrinkles away. In addition to buying wrinkle cream, there are four healthy skin habits that will give your skin a healthy and youthful appearance.
1. Protect yourself from the harmful UV rays from the sun. UV rays are most harmful between 12:00 p.m. and 4:00 p.m. Light clothing, hats, and shade, protect your skin from direct sunlight and prevent sunburn and dry skin which can cause premature wrinkles in the skin.
2. Use at least SPF 15 sunscreen everyday. Not even cold and cloudy weather will protect you from those harmful UV rays. Replacing everyday products with ones that contain SPF 15 will make wearing sunscreen effortless.
3. Keeping your skin hydrated with moisturizer will temporarily mask unwanted creases and prevent new ones from developing. Applying moisturizer daily is a great healthy skin habit and applying one that contains at least SPF 15 is even better!
4. Break your smoking habit for great skin care. Not only does smoking cause you to make exaggerated facial expressions, it inhibits the blood flow around your mouth causing wrinkles that you would not get from natural aging.
Aging and wrinkles are a part of life. In order to diminish the appearance of wrinkles and help ward off as many wrinkles possible, buy wrinkle cream and practice the four healthy skin habits. Protect your skin from direct sunlight, use SPF 15 sunscreen, use moisturizer, and quit smoking for great looking skin at any age.
