Application
Sunscreens should be applied at least 30 minutes prior to going out in the sun. Sunscreens absorb ultraviolet [UV] light in certain wavelengths. The UVA rays can cause long-term effects and contribute to photoaging and wrinkles. UVB rays are responsible for short-term effects like sunburns. UV light can easily degrade sunscreen, so its crucial to reapply every few hours for maximum effectiveness.

Sunscreen vs Sun Block

Avobenzone[Butylmethoxydibenzoylmethane], Octylmethoxycinnamate and Oxybenzone are common ingredients in many chemical blockers these days.

In contrast, sun blocks, also known as physical blockers, primarily sit on top of the skin and reflect the suns UV rays prior to its penetration into the skin. The earliest physical blockers included zinc oxide or titanium dioxide [think of the white paste on a lifeguards nose]. Todays formulations are micronized, allowing more even coating and a lighter feel on the skin. Because sun blocks do not absorb into the skin, they are an ideal choice to use on children and infants aged older than 6 months. Many products on the market do contain both physical and chemical blockers. 

UVA [ultraviolet-A] long- wave solar rays of 320-400 nanometers [billionths of a meter]. Although less likely than UVB to cause sunburn, UVA penetrates the skin more deeply, and is considered the chief culprit behind wrinkling, leathering, and other aspects of photo aging. The latest studies show that UVA not only increases UVBs cancer-causing effects, but may directly cause some skin cancers, including melanomas.

UVB [ultraviolet-B] short-wave solar rays of 290-320 nanometers. More potent than UVA in producing sunburn, these rays are considered the main cause of basal and squamous cell carcinomas as well as a significant cause of melanoma.

UVC [ultraviolet-C] shortest from the sun, usually does not reach the earths surface being absorbed by the ozone layer above the earth. Occasionally articles are written on the ozone depletion and the possible exposure to UVC where only a brief exposure can cause light sunburn. Prolonged exposure to UVC is considered fatal.

SPF [sun protection factor]

Solarin 60 has sun protection factor [SPF] 60. The SPF of any sunscreen is calculated as

SPF= Time needed to produce sunburn with sunscreen / Time needed to produces unburn without sunscreen

The SPF of any sunscreen reflects the products screening ability only for UVB Rays. It means that SPF is not a measure of UVA rays. However, many sunscreens products with ingredients such as titanium dioxide, zinc oxide, Octylmethoxycinnamate and Butylmethoxydibenzoylmethane also provide protection against UVA rays. These sunscreen products, apart from having their own SPF, are labelled as Broad spectrum sunscreens to indicate their protection ability against UVA as well as UVB.

The Japanese have a rating system which reflects a sunscreens ability to protect specifically against UVA. This rating is known as Protection Factor of UVA or PFA. According to this system Solarin 60 has PA +++ grading. This grading comes from Japanese Cosmetic Industry Association [JCIA] and represents a roughly UVA protection factor. PFA is calculated as
 
PFA= MPPD of protected area / MPPD of unprotected area

Where MPPD is Minimum Persistent Pigmentation Darkening [2 to 4 hours after exposure to UVA] Unlike SPF which can range from any number between 2 to 60 or even higher, the PFA grading has been assigned following three categories;

PA+ = PFA >2 - <4
PA++ = PFA >4 - <8
PA+++ = PFA >8


Why I Need Sun Protection 

Sun Effects on Skin Information / Repeated Sun Exposure is responsible for

  • Pigmentation Changes such as freckles, brown spots, liver spots, uneven skin tone or hyperpigmentation signal the first signs of sun damage. More than 90% of sun damage skin presents darker colour changes before wrinkles or fine lines appear.
  • Hypopigmentation no colour or pigmentation permanent white spots.
  • Telangiectasia [tee-lang-jeck-tah-zee-ah], permanent dilation of small blood vessels, spider veins. Often on the face, neck and chest, giving the skin a constant red flush.
  • Wrinkles premature or accelerated aging called photo aging. The Velcro like layer holding the epidermis [top layer] and the dermis [second layer] together is flattened allowing the two layers to slide in different directions causing bruising. UVA rays destroy the collagen and elastin in the dermis causing the layer to shrink and crack allowing the epidermis to hang off the body like baggy clothes responsible for loose or redundant skin.
  • Epidermal Thickening occurs as protection against the sun the texture may be rough to the touch. Clients often say they never feel pain or discomfort they have tough skin.
  • Senile Comedones blackheads caused by repeated sun exposure prominent on construction and road workers. Actinic Kerotoses actinic is the Greek word for sun, keratoses is the medical name for callous = sun callous = scaly lesions often precancerous.
  • Basal and squamous cell carcinoma also the fastest rising cancer melanoma. Melanoma rates in children less than 15 years increased by 60% between 1992 and 2001, according to the National Cancer Institute. The melanoma rate nearly doubled between 1973 and 1994 for people ages 15 to 29 and increased about 10% since then. It is the most diagnosed cancer in women ages 22 to 29.

 


Ingridents

Chemical UVA sunscreen/sunblock agent Avobenzone [Parsol 1789, Eusolex 9020, Escalol 517]
Type Chemical
Range of UV spectrum covered UVA [both UVA-1 and UVA-2]
Wavelengths covered 310-400 nm, which covers all of UVA
StabilityAvobenzone degrades in the sunlight, which leads to loss of protective effect. The rate of degradation can be reduced by photo stabilizers. However, photo stabilizers may increase the risk of skin irritation.
Summary Abobenzone is one of the very few chemical sunscreens with good coverage of UVA spectrum. Abobenzone is relatively nonirritating, although, as with many skin care ingredients, the possibility of low-level topical or systemic toxicity with long-term use remains unresearched. Abobenzone degrades in sunlight [especially if mixed with inorganic sunscreens] and loses effectiveness over time. Development of stabilized and microencapsulated versions of avobenzone is promising and may reduce the above drawbacks.
DetailsAvobenzone is an oil soluble chemical agent capable of absorbing light throughout the entire UVA spectrum. It is one of the very few comprehensive chemical UVA sun blocks in widespread use. Avobenzone appears to be relatively non-toxic and rarely causes skin irritation. However, as with many synthetic chemicals, it is unclear whether avobenzone or its degradation products may produce low-level toxicity with long-term use.
Chemical UVB sunscreen/sunblock Octylmethoxycinnamate [octinoxate]
Type Chemical
Range of UV spectrum covered UVB
Wavelengths covered 280-320 nm
Stability When exposed to sunlight Octylmethoxycinnamate is converted into a less UV absorbent form [from E-octyl-p-methoxycinnamate into a Z-octyl-p-methoxycinnamate]. This conversion can be partly prevented by certain other UV blockers, particularly bemotrizinol [Tinosorb M].
Summary Octyl methoxycinnamate [octinoxate] is a chemical sun blocking agent that absorbs ultraviolet radiation in UVB range. When exposed to sunlight octyl methoxycinnamate is converted into a less UV absorbent form, which reduces its effectiveness. This conversion can be partly prevented by certain other UV blockers.
Physical UVA+UVB sunscreen/sunblock Titanium Dioxide
Type Physical [ Microfine Titanium dioxide]
Range of UV spectrum covered UVA [better covers UVA-2 than UVA-1], UVB
Wavelengths covered good uniform coverage between 290-350 nm; insufficient coverage between 350-400 nm, especially in microfine/nanoparticle forms
Stability Regular titanium dioxide is highly stable under most conditions. However, it has some photocatalytic activity [i.e. promotes reactions between other chemicals], especially in direct sunlight. Titanium dioxide nanoparticles appear to have much greater photocatalytic activity than regular titanium dioxide powder and might trigger formation of harmful free radicals when exposed to sunlight. Most manufacturers of titanium dioxide nanoparticles coat them to reduce or eliminate such effects.Titanium dioxide is a physical sunscreen protecting against UVB and short UVA light. It has a long history of seemingly safe use and is not irritating.
 
Physical UVA+UVB sunscreen/sunblock Zinc Oxide
Type Physical [Micronized Zinc oxide]
Range of UV spectrum covered UVA, UVB
Wavelengths covered good uniform coverage between 290-400 nm, and some coverage up to 700 nm
Stability Regular zinc oxide is highly stable under most conditions; minimal reactivity may occur, especially in direct sunlight. However, zinc oxide nanoparticles are far more reactive/catalytic than regular zinc oxide powder. Most manufacturers of zinc oxide nanoparticles coat them to reduce or eliminate such effects.
Summary Regular zinc oxide is one of the most broadly effective, established and safe sun blocking ingredients available. Also, it is difficult to achieve high SPF [UVB protection measure] with zinc oxide alone. Therefore, in high SPF sunscreens, it is generally combined with chemical UVB blockers.
Details Zinc oxide is a physical sun blocking agent that works primarily by reflecting/scattering ultraviolet light. It has a broad range of effectiveness, covering UVB as well as both short [320-340 nm] and long [340-400 nm] UVA. Regular zinc oxide also blocks visible light up to wavelengths 700 nm, whereas zinc nanoparticles block only up to 380 - 400 nm, depending on the specific formulation. As a single ingredient, zinc oxide is the broadest range sunscreen on the market. Zinc oxide has a long history of safe use. It is not irritating and compatible with sensitive skin. In fact, zinc oxide is a skin protectant and anti-irritant, and is widely used in treating various forms of dermatitis/skin irritation, including diaper rash. The main complaint about zinc oxide-based sunscreens is that they may leave unsightly white residue. In fact, the concentrations of ordinary forms zinc oxide required for high degree of protection against the full range of UVA and UVB inevitably produce some whitish tint. This problem has been partly addressed by the advent of zinc oxide nanoparticles as a sunscreen agent . Zinc oxide nanoparticles have different optical properties and tend to produce much less whitish tint than regular powdered zinc oxide. Yet, early research indicates that zinc oxide nanoparticles retain the capacity to protect from UVA and UVB light.
Vitamin C + E enhancing stability and effectiveness of topical ascorbic acid
Most vitamin C derivatives on the market, including ascorbyl palmitate and magnesuim ascorbyl phosphate, consist of the ascorbic acid fragment [ascorbyl] and a fragment of another acid [e.g. palmitate or phosphate]. Recent research indicates that new vitamin C derivatives consisting of multiple chemical fragments bound to a single ascorbic acid fragment may work even better. These new derivatives are more stable compared to both vitamin C and older derivatives. Furthermore, some of these newcomers [particularly the so-called tetrasubstituted lipophilic ascorbates] also appear to be more powerful boosters of collagen synthesis. Even though relatively few skin care products currently on the market contain these new compounds, they may become widely used as more evidence of their benefits accumulates.
Vitamin E is a fat soluble antioxidant. In living systems, vitamins C and E can regenerate each other and thus potentiate each others antioxidant effects. While the capacity of vitamin E to protect vitamin C from oxidation in a water solution is relatively modest, vitamin E enhances the antioxidant effects of vitamin C when they are co-applied to the skin. Therefore, even if some of the vitamin C in a product is degraded, the remainder works better in the presence of vitamin E. Studies indicate that the combination of vitamins C and E provide better protection from UV-induced damage than either vitamin alone. On the other hand, vitamin E appears to have little effect on the ability of vitamin C to stimulate the synthesis of collagen.
