  • Clinical Research

    Sunlight that reaches the earth’s surface is composed of three wavelength components, namely Ultraviolet (UVR), Visible (VIS), and Infrared (IR) radiation. Approximately 6% of the solar spectrum is UVR (200 - 400 nm), 52% is Visible Light (400 - 760 nm), and the remaining 42% is IR (760 - 10^6 nm).

    Fortunately, the most energetic form of UVR, UVC (100 - 280 nm) does not reach ground level because it is effectively absorbed by the stratospheric ozone layer. Of the UVR that impinges upon the skin’s surface, about 5% comprises UVB and 95% comprises UVA. UV within 280 nm - 400 nm induces photodamage including sunburn, pigmentation, wrinkle formation, and cancer.

    UVB radiation is biologically active and is ‘partially’ filtered by the ozone layer. It penetrates the superficial layers of the skin, down to the basal layer of the epidermis, where it generates harmful reactive oxygen species (ROS), resulting in inflammation,  sunburn and skin ageing.

    UVA, on the other hand, has lower energy than UVB but is present in larger amounts. UVA radiation (315 - 400 nm) penetrates deeper into the skin and reaches the dermis. UVA generates ROS that alters proteins, lipids and DNA.

    Sunscreen helps by reducing exposure to UVR, specifically UVB and UVA, primarily from the sun. To prevent sunburns and protect the skin from serious damage, sunscreens must meet certain criteria. They should be photostable, dissipate the absorbed light energy through photophysical and photochemical pathways without the formation of harmful reactive intermediates, and should be well tolerated.

    The active ingredients in sunscreens work by creating UV filters that keep harmful UV rays from penetrating the skin. There are two types of sunscreens – mineral sunscreens and chemical sunscreens. Each type uses a different mechanism for filtering UV rays and protecting the skin from damage.

    Mineral sunscreens sit on top of the skin’s surface, acting as a physical blocker by deflecting and scattering UV rays away from the skin like tiny mirrors. Because they block UV rays at the surface level, mineral sunscreens protect against both UVA and UVB rays.

    Also, because mineral sunscreens create a physical barrier, they are effective as soon as they are applied, so there is no need to wait.

    Mineral sunscreens tend to have a white-ish cast to them and can be visible on the skin. Also, because they sit on the skin’s surface, mineral sunscreens can be rubbed, sweated, or rinsed off easily, which makes frequent reapplication a necessity.

    They also must be applied liberally to ensure adequate protection. Because the nanoparticles in mineral sunscreens should not be inhaled, it is best to avoid spray and powder formulations to minimize lung exposure. Mineral sunscreens contain the active ingredients titanium dioxide and zinc dioxide or a combination of the two.

    Pros: full protection from UVA and UVB rays; effective immediately; will not clog pores

    Cons: frequent reapplication is needed; may leave a white cast on the skin; spray and loose powder formulations should be avoided

    On the other hand, Chemical Sunscreens are absorbed into your skin and sit in the deeper layers. They absorb UV rays and change them into heat, then release the heat from the skin.

    Since UV rays must penetrate the skin to reach these chemicals, chemical sunscreens may not protect against all UVA rays, which still causes damage to the deeper layers of the skin.

    Because chemical sunscreens take about 20 minutes to be effective, planning is required.

    Also, direct light causes the chemicals to be used up more quickly, so re-application must be more frequent when you are in direct sunlight. The heat-releasing nature of chemical sunscreens can be problematic for sensitive and rosacea-prone skin, as well as for individuals with hyperpigmentation.

    The heated skin can cause an increase in existing brown spots. Chemical sunscreens can also clog pores and be problematic for acne-prone skin. Chemical sunscreens contain oxybenzone, avobenzone, octinoxate, octocrylene, octisalate, homosalate, or combinations thereof.

    Pros: less product is needed per application to offer protection; thinner and easier to spread on the skin; applies invisibly

    Cons: allows some UVA exposure; requires time to be effective; can exacerbate acne, rosacea, and hyperpigmentation; frequent application required.

    The CosIQ SPF serum is a hybrid (a blend of chemical and mineral sunscreens) that provides broad-spectrum UVA, UVB, UVC and IR protection which leaves no white cast and is sweat as well as water resistance. This double encapsulated formula also provides protection against pollution and is an antioxidant support matrix, lightweight vanishing serum for easy wearability every day.
