For the Curious
Approximately 80% of skin aging on the face can be attributed to ultraviolent (UV) exposure and especially in those with lighter skin, UV exposure can lead to skin cancer. For these reasons, the American Academy of Dermatologists (AAD) recommends daily use of a broad spectrum sunscreen with SPF 30 or above for optimal protection.
However what is the meaning of the terms broad spectrum and SPF? There are two types of UV rays: UVA and UVB. While UVA rays cause photo-aging of the skin, UVB rays cause sunburn. The term SPF specifically relates to protection from UVB rays that cause sunburn, rather than protection from UVA rays that cause photo-aging. SPF 30 means that it would take you 30 times longer to burn with the sunscreen than without, and an SPF 30 product blocks about 97% of UVB rays. The AAD also recommends a sunscreen that is labeled “broad-spectrum” as this specifically means that there is demonstrated protection against UVA rays as well as UVB (Guan et al. 2021, Henderson et al. 2022).
Sunscreens can either be physical with zinc oxide or titanium dioxide, or chemical with avobenzone, octinoxate, and oxybenzone amongst others. While physical sunscreens are a physical barrier that scatter or reflect UV, chemical sunscreens absorb UV rays. Chemical sunscreens absorb into the bloodstream and the long-term safety effects are unknown and hence are rated by the FDA as needing further evaluation. The FDA only rates zinc oxide and titanium dioxide as generally regarded as safe and effective (GRASE). In recent years as more people become conscious of the health ratings of skincare products particularly when pregnant or breastfeeding, physical mineral sunscreens have become more popular (Bennett and Khachemoune 2022). Of the two, zinc oxide has a broader UVA-UVB absorption curve than titanium dioxide (Schneider et al. 2019). The Sun Protector is a 100% mineral sunscreen containing 18.6% zinc oxide.
The main complaint when it comes to mineral sunscreens is that they can leave a white cast. If zinc oxide particles are made smaller (micronized) and even nano-sized, they no longer will leave a white cast. However, there are some downsides to micronized mineral sunscreens.
The first is that nano sized zinc oxide is toxic to mammalian cells. This is because it can penetrate through the cell’s covering and generate free radicals inside the cell which do damage (Liao et al. 2020). That being said, if you have a healthy skin barrier, even nanoparticles of zinc oxide do not penetrate into the skin to any significant degree avoiding this toxicity for the most part. Studies show no to minimal risk of toxicity of nano zinc oxide. However, the exception is damaged skin where a compromised skin barrier does allow the penetration of nano zinc oxide (Schneider et al. 2019). Hence, the white cast is part and parcel of a sunscreen that is safe for those with a damaged skin barrier.
The second is that along with chemical sunscreens, nano-sized zinc oxide and titanium oxide are considered toxic to coral and marine life by the National Oceanic and Atmospheric Administration and hence are not environmentally friendly (Guan et al. 2021). This being said, chemical sunscreens are considered the main drivers of harm to coral reefs and aquatic animals (Schneider et al. 2019). Nonetheless, the white cast is part and parcel of a sunscreen that is environmentally friendly.
Third, zinc oxide also protects against visible light only when it is pigmentary size and not when it is micronized. UVA rays that cause photo-aging increase enzymes involved in collagen degradation and when combined with visible light will induce increased and prolonged pigmentation (Guan et al. 2021). Hence, if you have hyperpigmentation issues, you want both protection from UVA and visible light with pigmentary size zinc oxide that leaves a white cast. In fact, the transparency of micronized mineral sunscreens is because they do not reflect visible light. In other words, the white cast and protection against visible light go hand in hand.
We recommend using both a vitamin C serum such as Glow Maker serum and sunscreen. A good broad-spectrum SPF 30 product is your first line of defense against UV rays and photoaged skin. However, even good sunscreens only block about half of the free radicals spawned from UV exposure. Antioxidant vitamin C serums help neutralize free radicals to protect your skin from harmful UV rays.
While physical sunscreens do not deplete across the day, vitamin C in the skin is quickly depleted by fighting UV damage or other free radical generating activities such as smoke and pollution throughout the day, topical vitamin C application twice a day may be useful to replenish levels when engaged in outdoors activities. Topical vitamin C and sunscreen work by differing mechanisms to protect your skin so the combination is ideal (Lin et al. 2005, Telang et al. 2013).
The Sun Protector also contains Vitamins C and E as well as plankton extract and botanicals that can offer some antioxidant protection. However, these are secondary in function and are not optimized in the way they can be in an antioxidant vitamin C serum such as the Glow Maker.
Yes you can. The Sun Protector is an 100% mineral sunscreen. The FDA only rates zinc oxide and titanium dioxide used in mineral sunscreens as generally regarded as safe and effective (GRASE). Chemical sunscreens (avobenzone, octinoxate, and oxybenzone amongst others) absorb into the bloodstream and the long-term safety effects are unknown and hence are rated by the FDA as needing further evaluation. Particularly when pregnant or breastfeeding, physical mineral sunscreens are recommended (Bennett and Khachemoune 2022). However, it is always advisable to double check skincare products and ingredients with your doctor and follow their protocol.
