What it is
"The Recalca method of use is to apply CF Serum Advanced to your skin and leave it on for five minutes." It conditions your skin for health and enhances the absorption of other serums. Two types of vitamin C (ascorbic acid and trisodium ascorbyl palmitate) bring clarity and firmness, leading to a brighter, more radiant complexion. \ Point 1 / {Amphiphilic vitamin C derivative APPS (trisodium ascorbyl palmitate)} A water-soluble vitamin C derivative that easily blends with water and an oil-soluble vitamin C derivative that easily blends with oil. The amphiphilic vitamin C derivative (APPS) has both a water-soluble and an oil-soluble portion, allowing it to penetrate and moisturize a wide range of areas within the skin where both water and oil mix. *Skin refers to the stratum corneum. \ Point 2 / {Contains naturally derived MAAs} Contains MAAs extracted from cyanobacteria. MAAs penetrate deeply into the stratum corneum, leading to plump, firm skin. Point 3: To maintain the stability of ascorbic acid, it is important to prevent it from oxidizing to dehydroascorbic acid. CF Serum Advance has three features to prevent oxidation within the container.

How to use
Although it is a serum, it can also be used as a toner first. We recommend taking two pumps, applying it to your face, and leaving it on for about five minutes until it is fully absorbed.

I was attracted to the high concentration of vitamin C, so I gave it a try. It has a clear, slightly thick texture and spreads easily. You have to leave it on for five minutes to let the vitamin C penetrate your skin. Waiting just five minutes is a pain. Even a small amount is sticky and makes your hair stick to it. I didn't really like it, but the next morning, my hair texture was completely different! I could tell it was smoother within just one day. I plan to continue using it.
I bought this product after a beauty consultant recommended it. I use it twice a day, once in the morning and once after a bath. It's not an oil, but it has an oil-like texture and is very moisturizing. For dry skin like mine, this amount is just right! I recommend leaving it on for 3-5 minutes after application and then applying a moisturizing lotion or similar product. I use it in combination with the same brand's mist lotion, and what surprised me was that after applying it after a bath, my skin still felt plump and absorbed into my skin the next morning! My skin seems surprised and pleased, and I plan to continue using it.
I've been using it for 1.5 months, but I'm starting to notice fine lines and pores due to dryness under my eyes. Because it contains a fairly high concentration of glycerin, it seems to be actually drying out my skin. It worked well on uneven skin tone and radiance, but that disappeared when I switched back to Environ skincare. It's a shame it doesn't suit me. The texture is a little thick, and using it late in the morning can smudge makeup. So, I apply it immediately after cleansing my face and applying Lactope Lotion, then layer on my toner and cream after a while. One pump in the morning and evening is enough, so I think it should last for more than two months. The biggest benefit I've noticed is that my skin tone has become even! I can now wear no foundation. I also notice a noticeable increase in firmness and radiance. I love skincare and have tried all kinds of skincare products, including Environ, Gaudi, BA, Obagi, and Cosme Deco. Recalca is my current favorite brand, combining the best of doctor's and department store cosmetics in effectiveness and feel.
I've repurchased this product about four times now. It's heavy! The texture is so heavy that I only use it at night. But when I use it again after a long time, my skin looks completely different!
