What it is
Contains a balanced blend of moisturizing and emollient ingredients. Its high moisturizing power protects the skin, leaving it hydrated, firm, radiant, and soft. The moisturizing formula adheres tightly to the skin, preventing moisture from escaping. Although it has a rich texture with a high concentration of oil, it changes to a texture that spreads smoothly as the oil melts when applied, leaving a finish that blends seamlessly into the skin. Recommended for those who want to incorporate oil beauty into their daily skincare routine.
Ingredients
How to use
After preparing your skin with moisturizer (lotion), take a pearl-sized amount and spread it over your entire face, starting from the center and working outwards. Then, press the product into your skin with both palms to thoroughly blend it in.

After using the 8g sample, I purchased the full-sized product. It's an oil-in-cream, but I like that it doesn't feel sticky at all until the next morning.
The texture is quite thick, and you can feel the oiliness immediately after application. This makes it comfortable for dry skin, and it doesn't leave skin feeling tight even after a while. My mother especially likes using it at night, and loves that it leaves her skin feeling moisturized until the next morning. It's a formula that prioritizes protection over lightness, so I think it's suitable for mature skin or those concerned about dryness. The scent is also mild, making it easy to use every day.
I use this together with the lotion from the same line. I use it in the mornings. It's perfect for winter, when I don't have much time but need moisture. I use it right after applying lotion. It has a refreshing citrus scent. The texture is soft, somewhere between a cream and a lotion, and it spreads easily and doesn't feel sticky. It keeps my makeup from clinging, so this is my go-to for winter mornings.
I was starting to worry about dryness and was trying out various skincare products when I saw a review on Suzykirei and decided to buy this. The texture is a mix of oil and cream, leaving my skin feeling moisturized and smooth, and it stays hydrated the next day. The scent is also great, with my favorite citrus notes. I'm very satisfied with this product, so I plan to continue using RMK for a while.
I usually use the oil from this line in the winter, but this year I also bought the cream! It's highly moisturizing but not sticky, so it's very easy to use!
