What it is
RMK skin care icon A treatment oil with dual effects, an oil layer and a moisturizing layer that provides a total approach to dryness and lack of firmness. A pre-care treatment oil that combines an oil layer that softens the skin and a moisturizing layer that fills the stratum corneum with moisture. By using it at the beginning of your skin care routine, it prepares the stratum corneum for subsequent moisturizing lotions to penetrate more easily. The double action of oil-based and water-based products provides a wrapping effect that prevents dryness and supports the skin's barrier function. It can also be used as a beauty oil or massage oil, promoting blood circulation and making skin firmer. Contains argan oil, which has a high moisturizing effect. The rich, yet non-sticky texture and floral citrus scent, a blend of eight essential oils such as orange and neroli, gently envelop the skin. The massage effect promotes blood circulation.

We're working on rolling out prepaid duties for more countries soon.
I have super dry skin, so adding oil makes it soft and moisturized, never drying out. It's also great that it's reasonably priced.
Just right for massage
Thinking it might be effective for inner dryness, I bought a small size to try it out. I'm planning to use it after a bath, but as soon as I put it on my hands, it gets absorbed right into my hands - amazing... So, if you want to use it on your face, it might be better to put a fairly large amount in your palm. Despite being an oil, it's not sticky (though I wouldn't say it's smooth), and it leaves your skin feeling bouncy after application. I'm layering lotion on top of this, but I wonder if I'm using it correctly. For now, I'd like to find a good way to use it. It would also work well if I mixed it with sunscreen or foundation, which are a little hard to spread.

I was given this when I had my foundation touched up, and although I decided not to buy it at the time, I liked the scent so much that I bought it on Suzykirei. It's perfect for the dry winter season.
