•In the US, Avobenzone is the only approved chemical filter that absorbs UVA rays, which helps to reduce skin aging caused by the sun. This would mean that octocrylene, homosalate, and octisalate all absorb UVB rays that are typically shorter in wavelength than UVA. So functionally, octisalate and homosalate perform similarly in absorbing UVB rays, which tend to be around 295-315nm.
• With this in mind, a combination of all 3 filters in our current FLA architecture contributes to broad spectrum performance.

•Following Sephora's Clean standards, Octocrylene was banned from Sephora in 2024. We thoughtfully formulated this product with Sephora Clean compliant filters while achieving a high broad spectrum SPF value of 60.

•No. We recommend using a water-resistant  SPF if swimming or sweating.

•Yes, it can double as a daytime moisturizer and SPF. It also layers well under makeup!

•SPFs should be applied as the last step in your skincare routine, and before makeup if makeup is being used. To maintain an SPF value, in our case: SPF 60, this product should be re-applied every two hours.

•[ Strengthens skin barrier in just 1 hour ]We have bio-instrumental data showing that with the use of YOUTHSCREEN, there was 25% less TEWL (trans-epidermal water loss) than compared to the untreated site (without YOUTHSCREEN). This concludes that YOUTHSCREEN helps keep more moisture in the skin barrier.

•[ +23% defense against pollution adhesion ] This test is typically done on cleansers to prove they remove pollution from the skin, which is what makes this metric is so impressive for a leave-on product. This claim states that with the use of YOUTHSCREEN, the skin is shielded against 23% of pollution adhesion versus an untreated site (without YOUTHSCREEN).

•[ +115% immediate hydration ] YOUTHSCREEN was tested to increase hydration by 115% immediately after use.

•[ Antioxidant activity helps defend against free radicals ] We love talking about antioxidants at YTTP! Constant oxidative stress can lead to premature aging, such as dullness, fine lines, and dryness. The presence of antioxidants help stabilize free radicals to defend against those effects. We formulated with 1% vitamin E for many reasons, but one being AOX activity. In addition, this ingredient is known for nourishing the skin for a softer feel overall.

•Pollution adhesion is the action of toxic airborne microparticles (PM 2.5) sticking to and accumulating on your skin throughout the day, whether inside or outside, and regardless of where you live. And depending where you live, these 2.5 pollutants can come from a multitude of sources, for example: pollen, dust, smoke, etc. Why is this so important in reducing? Pollution on skin can lead to skin un-comfortability, dullness, oxidative stress, skin barrier damage, etc.

•SPFs should be applied as the last step in your skincare routine, and before makeup if makeup is being used. To maintain an SPF value, in our case: SPF 60, this product should be re-applied every two hours.

•With the 4 factors of skin health, we focus on factors that might contribute to premature aging, alongside constant sun exposure. This product is about protecting what you already have (nothing wrong with aging! 😊), versus allowing UV damage and pollutants to cause unnecessary, premature aging. We formulated this product for a high Sun Protection Factor of 60 (SPF 60) and impressive level of antioxidant activity to help promote skin longevity.

•UV rays, whether you're in low or high exposure zone, reach you everyday, indoors and especially outdoors! Using a broad spectrum sunscreen helps protect the skin from UVA rays, known for causing photodamage, and UVB rays, known for causing sunburns. Protecting from both helps reduce the potential risk of premature skin aging, as well as skin cancer.

•The difference between the two filters are that chemical sunscreens absorb into the skin and absorb UV rays, and mineral sunscreens sit on the skin and deflect UV rays. There is a misconception that mineral is "safer," likely because of the fact it sits on the skin, leaving less room for ingredients to interact with someone who might be allergic to them. Those with darker skin tones are almost always limited to chemical sunscreens because of the non-negotiable white/purple cast. For us, a chemical sunscreen made the most sense to develop first to prioritize inclusivity, and that it has the potential to provide more skincare benefits than that of a mineral sunscreen.
