Science-Driven Skincare

At the heart of OS-01 BODY SPF lies a deep commitment to scientific rigor and evidence-based formulation. Like all OneSkin products, this sunscreen was born in the OneSkin lab, where our team of dedicated researchers refined its unique blend of active ingredients. Together with the OS-01 FACE SPF (formerly OS-01 SHIELD), these two sunscreens represent a groundbreaking advancement in the field of sun protection. When used in conjunction with our OS-01 topical supplements, you can experience the maximum benefits of this innovative peptide and start to see your skin looking and behaving like its younger self.

OS-01 BODY SPF Protects Skin From UV-induced Collagen Degradation

With broad-spectrum SPF 30+ and PA+++, OS-01 BODY SPF blocks out more than 97 percent of harmful UVB rays (see why a higher SPF isn’t necessarily better here). Our broad-spectrum formula protects your skin from the kind of UV damage that can degrade collagen and accelerate aging. Keep in mind that sun damage is the number one cause of skin aging. (3)OneSkin scientists treated ex vivo human skin samples with OS-01 BODY SPF and exposed these samples to UVB radiation to measure collagen density against a control sample. This three-color dye procedure, known as Masson's Trichrome staining, displays collagen (blue), nuclei (dark brown), muscle tissue (red), and cytoplasm (pink).

Representative histological images of ex vivo human skin samples (59y) that were treated with nothing (No Treatment) or OS-01 BODY SPF with and without 1J/cm2 UVB radiation and stained with Masson’s Trichrome after 24hrs.
Upon examination under the microscope, the scientists observed that the skin treated with OS-01 BODY SPF displayed a more cohesive stratum corneum and an increased collagen density, as indicated by the deeper blue color in the epidermis even after exposure to UVB radiation. When they quantified the collagen density results, the data revealed that OS-01 BODY SPF effectively protected the skin from this collagen degradation, unlike the benchmark SPF. By protecting your skin from this radiation, OS-01 BODY SPF helps prevent the visible signs of UV aging.

OS-01 BODY SPF Reduces the Effects of UV Aging

While the damaging effects of UV radiation on the skin are well-documented, the story of skin aging is complex. Skin aging involves both extrinsic and intrinsic factors. Extrinsic aging accelerators include UV radiation and other environmental exposures. Intrinsic aging includes increased levels of senescence and inflammation. Along with the breakdown of essential skin components like collagen and hyaluronic acid, skin aging is a physical process within the skin that is accelerated by UV exposure.To better understand how OS-01 BODY SPF mitigates skin aging, we compared the gene expression levels of key biomarkers associated with aging and skin deterioration of ex vivo human skin samples treated with OS-01 BODY SPF against a control. The results showed that OS-01 BODY SPF decreased the levels of key biomarkers associated with the aging process and cellular senescence. Specifically, the product was shown to reduce the expression of p16, a marker of cellular senescence, as well as IL-8, a pro-inflammatory cytokine. Additionally, OS-01 BODY SPF was found to mitigate the degradation of hyaluronic acid (as indicated by lower HYAL1 levels) and collagen (as shown by decreased MMP-1 levels).

OS-01 BODY SPF Offers Superior Antioxidant Power

While UV radiation is undoubtedly the biggest extrinsic skin aging factor, it's not the only culprit. Ionizing radiation (IR), blue light (HEV light), and pollution are all known to generate free radicals, unstable molecules that have one or more unpaired electrons. (4) These free radicals wreak havoc in the skin damaging DNA and proteins leading to more visible signs of skin aging. Luckily these free radicals can be neutralized by antioxidants in your diet and skincare. To ensure that OS-01 BODY SPF covers the multifaceted assault on skin health, our formula is infused with a blend of potent antioxidants like vitamin C, green tea, acai, and tara fruit extracts. To test how well these antioxidants work to neutralize free radicals, our scientists put OS-01 BODY SPF to the test, comparing its antioxidant capacity against strong antioxidants like green tea oil and commonly used "anti-aging" SPFs that contain antioxidants.

Intrinsic aging:Intrinsic aging happens over time, central to which is cellular senescence. This is where the OS-01 peptide comes into play. As the first body SPF to be formulated with this cutting-edge compound, OS-01 BODY SPF is designed to target a key driver of intrinsic skin aging, helping to slow the process at the cellular level. Extrinsic aging:On the other hand, to tackle extrinsic aging, OS-01 BODY SPF utilizes non-nano zinc oxide to provide broad-spectrum protection against UVA and UVB rays, as well as a blend of potent antioxidants to help neutralize the free radicals that can be generated by exposure to blue light, infrared radiation, and pollution. This protects the skin from various aging accelerators.
  • Pollution. Exposure to pollutants increases ROS and inflammation, exacerbating photoaging and leading to a more aged appearance. (5)
  • Chronic infrared radiation. Exposure can generate free radicals and ROS by penetrating the dermis, degrading proteins like collagen, and contributing to premature skin aging. (6)
  • Visible light. Up to half of free radicals produced in skin may be due to visible light, including blue light emitted by electronic screens - high doses and chronic exposure can generate damaging free radicals, though low doses may have some benefits for skin conditions. (7)

Usability and Skin Compatibility

When choosing a UV filter, we opted for non-nano zinc oxide, as current data suggests it presents the lowest risk of health effects and the maximum broad spectrum protection compared to other chemical and mineral alternatives. However, non-nano mineral sunscreens are criticized for their chalky, gritty texture and the unsightly white cast they can leave on the skin due to the large size of particles. OS-01 BODY SPF, however, was designed to be lightweight, absorb quickly, and blend seamlessly.To ensure that OS-01 BODY SPF not only provides exceptional benefits to the skin but also an excellent experience when you apply it, our team conducted a one-week beta test with 30 randomly selected participants. The results were overwhelmingly positive:
  • 100% of users agreed that OS-01 BODY SPF applied evenly and smoothly.
  • 96.7% of users agreed that the product felt light and weightless on their skin.
  • 93.3% of users, comprising skin tones from Type I to Type VI, agreed that the product blended seamlessly with their skin tone.
Moreover, zinc oxide is known to be suitable for all skin types, including sensitive, oily, acne-prone, and dry skin. Its anti-inflammatory properties make it beneficial for those with inflammatory skin conditions, while its antibacterial qualities can help control oil production and reduce secondary infections associated with acne. (8)For those with dry skin, the protective barrier created by zinc oxide can help prevent transepidermal water loss, which becomes increasingly important as we age and the skin's natural ability to regulate moisture decreases. When used in conjunction with the OS-01 topical supplements - OS-01 FACE, BODY, and EYE - users can experience the maximum benefits of the OS-01 peptide.
