Hydrating Anti-Aging Skincare in Three Steps Post-Cleansing

A key feature of "OSAJI KAI" is its glycerin-rich formula for dryness care. Glycerin, which retains moisture on the skin and fills the stratum corneum cells with hydration, is highly concentrated in all products.

The skin naturally has a function to produce glycerin (moisturizing) and short-chain fatty acids (pH adjustment) by secreting sebum. However, as we age, sebum secretion decreases, leading to a reduction in the absolute amount of glycerin and short-chain fatty acids.

Additionally, it replenishes short-chain fatty acids (lactic acid) to maintain the skin's slightly acidic state, which promotes turnover. Furthermore, two antioxidant ingredients, "Alpenrose Extract" and "VC Glycerin," effectively prevent the generation of active oxygen, blocking melanin production and glycation (carbonylation) before they occur. They promote healthy skin, strengthen the stratum corneum cell membranes, and support the function of Vitamin C.

"OSAJI KAI" proposes a three-step care routine. After cleansing, apply the anti-aging lotion "OSAJI KAI Revelation Toner" to support the skin's fundamental strength. Layering it increases the dewy feel, allowing for adjustment of hydration levels to your preference.

Next, layer the anti-aging serum "OSAJI KAI Revelation Serum." It enhances skin's moisture density, leading to plump, firm skin. Finally, apply "OSAJI KAI Revelation Moisturizer." It forms a water-soluble protective film, keeping skin hydrated for extended periods. Suitable for use before makeup in the morning and for nighttime care.
