How To Apply

Apply generously to cleansed, toned and hydrated skin, pay special attention to sun-exposed areas, and re-apply if active, sweaty, or after swimming. For optimal results use together with Shunly antioxidant vitamin B,C,E + Ferulic Treatment to help neutralize free radicals and maximize sun protection.

1. Place one to two pumps to hand.
2. Apply to skin by using a finger to make a lot of dots over the face, neck, and body. Follow by tapping motion (do not apply like cream) until fully absorbed into the skin.

Ultraviolet C (UVC) - (100-280 nm) shortest wavelengths UV rays that can photo damaging to the skin, results in the skin burn with exposure. UVC generated by the sun is screened from reaching us by the protective ozone layer.

Ultraviolet B (UVB) - (280-320 nm) intermediate wavelength of ultraviolet rays and causes the initial appearance of erythema, commonly called "Sunburn": usually perceived as redness. It primarily damages the epidermis (the outermost layer of the skin). The superficial redness and painful irritation caused by UVB subside after a relatively short period of time, but the underlying damage remains and accumulates, potentially resulting in basal cell and squamous cell cancers. Excessive exposure to UVB is the foremost promoter of premature aging of the skin. Some indoor tanning devices also emit UVB. In addition to staying out of the sun between 10 a.m. and 4 p.m. when UV rays are strongest, you can protect UVB by applying sunscreen, wearing protective clothing, sunglasses, and avoiding tanning devices.

Ultraviolet A (UVA) - (320-400 nm) - UVA is the longest of the ultraviolet wavelengths. While energy from the shorter UVB wavelength is absorbed in greater amounts in the epidermis and in keratinocyte DNA, energy from UVA penetrates more deeply into the dermis. In addition to skin darkening (tanning), UVA-induced photodamage, usually seen as dryness, uneven pigmentation, inflammation, fine wrinkles, and skin cancer. Even a low dose of UVA can cause photodamage leading to wrinkles and sagging skin. UVA adversely affects the deep dermis resulting in a loss of the elastic quality of its supportive collagen, causing premature aging. UVA represents 90-95% of terrestrial UV radiation. Unlike the shorter UVB wavelengths, UVA easily penetrates window glass and retains essentially the same energy level all day long, every day of the year, presenting the same damaging effects at 9 a.m. in December as it dies at 4 p.m. in July. As with UVB, we can protect ourselves against UVA by staying out of the sun, applying sunscreen, wearing protective clothing and sunglasses, and avoiding indoor tanning devices. Use products that address this wavelength to specify "UVA protection" or "Broad-Spectrum Protection" on the label. However, "Broad-Spectrum Protection" is not total spectrum protection, and safely maintaining unaltered essential biological functions can only be achieved by well-balanced, photostable sunscreens that protect against the entire spectrum of UV radiation. Unfortunately, there is presently no standardized indicator, numerical or otherwise, to signify the level of protection against UVA, but sunscreens containing Zinc Oxide and Titanium Dioxide will protect against UVA radiation.
