While OS-01 EYE CREAM and OS-01 FACE RICH CREAM share our proprietary OS-0 Peptide™, each formula is tailored to the specific needs of the skin it should be applied to.

The skin around your eyes is thinner and experiences higher levels of senescence than the skin on the rest of your face. Because of these differences, OS-01 EYE CREAM is formulated with the optimal concentration of the OS-01 Peptide™ for this accelerated aging, plus it contains supporting ingredients specifically designed to support the delicate eye area skin. OS-01 FACE RICH CREAM is specifically designed for the skin on the face and neck to deliver deep, replenishing hydration for dry, depleted skin through an optimized level of the OS-01 Peptide™, plus powerful humectants and barrier-supporting lipids. 

Using each product where it's designed to go helps you get the most out of your routine.

With twice-daily use, one 50ml jar should last approximately 1–2 months. This varies from person to person depending on how much you use per application, but many people find that 1–2 pumps generously cover the face and neck.

OS-01 FACE RICH CREAM has a rich, fast-absorbing texture that melts into your skin without feeling greasy or heavy.

OS-01 FACE RICH CREAM can be used day and night, depending on your skin's needs. You can use OS-01 FACE MOISTURIZER as a lightweight daytime moisturizer and OS-01 FACE RICH CREAM as a night cream—or use OS-01 FACE RICH CREAM morning and evening if you have dry, depleted skin, are in a dry climate or season, or just want a little extra hydration.

OS-01 FACE RICH CREAM can work well under makeup, but we always recommend patch testing with your specific makeup to ensure the combination works well for you. We recommend giving it a few minutes to fully absorb before applying makeup on top.

Both OS-01 FACE MOISTURIZER and OS-01 FACE RICH CREAM contain the OS-01 Peptide™ in concentrations optimized for efficacy, but they differ in their textures and their supporting ingredients. The choice between the two depends on your skin type and hydration needs. 

OS-01 FACE MOISTURIZER is a lightweight daily moisturizer designed for oily, combination, and normal skin. Supporting ingredients include a triple-weight hyaluronic acid, niacinamide, and oleic pau mulato extract, which provide instant hydration, barrier support, and antioxidant defense.

OS-01 FACE RICH CREAM is a deeply replenishing cream designed for dry, depleted, or mature skin. Supporting ingredients include Tremella fuciformis mushroom, torula oil, and vegan collagen amino acids  to draw moisture deep into the skin and lock it in.

While you can layer OS-01 FACE MOISTURIZER and OS-01 FACE RICH CREAM, you certainly don't need to in order to get optimal benefit from the OS-01 Peptide™. Each formula is calibrated with a precise amount of the OS-01 Peptide™ to deliver an effective amount to skin and to account for the different viscosity and supporting ingredients.

If you already layer a rich cream over OS-01 FACE MOISTURIZER, you may consider switching to OS-01 FACE RICH CREAM for the same OS-01 Peptide™ benefit but with fewer steps.

Not exactly. How much peptide reaches the deeper layers of skin depends on the supporting ingredients and the formula's viscosity—not concentration alone. Because OS-01 FACE RICH CREAMis a thicker, richer product, it requires more peptide to achieve that same optimal efficacy as OS-01 FACE MOISTURIZER. So while OS-01 FACE RICH CREAM contains a higher concentration of the peptide, both provide effective levels to the skin.

OS-01 FACE MOISTURIZER provides lightweight hydration and is suitable for oily, combination, and normal skin. OS-01 FACE RICH CREAM delivers deep hydration in a rich, replenishing texture and is suitable for dry, depleted, or mature skin. As seasons and climates change, you may choose to switch between the two depending on your hydration needs.

Yes. You may choose to use OS-01 FACE MOISTURIZER in warmer, more humid months and OS-01 FACE RICH CREAM when skin feels drier in winter. Because both contain optimal levels of the OS-01 Peptide™, you get skin longevity benefits either way.

Yes—the identical OS-01 Peptide™, optimized with the most effective concentration for each formula's viscosity and supporting ingredients.

Each formula contains the OS-01 Peptide™, which targets the dysfunctional senescent cells that drive visible skin aging. OS-01 RICH FACE CREAM was specifically engineered for mature, depleted skin with supporting ingredients that address the chronic dehydration and loss of firmness often experienced with age. OS-01 FACE MOISTURIZER may be more suitable for younger skin that doesn’t require deep hydration. Because senescent cells start to accumulate in your 20s, the best strategy to resist visible signs of aging is to prevent their accumulation before they become visible.

OS-01 FACE RICH CREAM is suitable for sensitive skin, non-comedogenic, dermatologist tested, fragrance free, and formulated without parabens, sulfates, phthalates, or other common irritants. Based on its formula and clinical testing, it has been awarded the National Eczema Association Seal of Acceptance™. Additionally, it contains barrier-supporting and hydrating ingredients, including a Triple Lipid Barrier Complex (ceramides, cholesterol, and free fatty acids), ectoin, and tremella mushroom extract—ingredients generally recognized for their gentle and soothing properties. In consumer testing, 87% of users agreed the cream deeply moisturizes and comforts dry skin.¹

That said, as with any new skincare product, we recommend patch testing before full application, especially for those with known sensitivities or reactive skin conditions.
