I have thin, sensitive skin, and until now I've only used it before my period or when my skin is rough or sensitive. However, when I broke out in an eczema all over my face for the first time for an unknown reason, this product was the best I could use without any irritation compared to the many basic skincare products for sensitive skin I have at home. It's one of those products I want to keep in stock at home as a talisman. It's also hygienic because it's a disposable product.
Protect your skin from all angles! CAC Gel Serum... With the sudden cold weather, many people are concerned about skin instability*... This is the solution to those instability* and dryness! *Skin changes due to seasons, etc.... This serum addresses skin concerns caused by a disrupted stratum corneum. It strengthens the skin's barrier function and regulates the stratum corneum before damage accumulates. It contains a carefully selected and exquisitely balanced blend of amino acids and sugars essential for healthy skin... Although it's called a gel serum, its texture is smooth and non-sticky. Its smooth texture makes it easy to combine with other skincare products, and its individual packaging makes it convenient for overnight stays away from home. It eliminates potentially harsh ingredients, making it suitable for all skin types... I love CAC's skincare because, despite its simplicity, I can clearly see the changes in my skin with continued use.
CAC is my favorite brand, and the changes it brings to my skin are obvious with continued use. It's additive-free cosmetics, and the term "skin-nurturing" is a perfect fit. The gel serum's texture is more watery than thick. Perhaps because of this, it absorbs smoothly into my skin, forming a film like a film. It doesn't feel sticky, but rather refreshing. However, it doesn't dry out my skin at all, and when I use it in combination with CAC's lotion, my skincare routine is complete. It's amazing how I don't feel like applying cream or anything else. Just the lotion and serum are enough. I wholeheartedly recommend it to anyone looking for a simple skincare routine. Ultimately, I realized that the quality of the ingredients and simplicity are what matter most when it comes to CAC.
I've used a variety of cac cosmetics, but this serum was too expensive for me. I was able to get it at a good price this time, so I tried it right away and it's great. I usually use a non-oil nighttime skincare routine, and recently I've been loving Curel's spray. This one isn't as sticky as I thought it would be, and it really does improve my skin's condition. I think it's also great for tired skin. I recommend it.
It's been a month since I started using it. In my case, if I continue to use it, my skin starts to feel irritated and I can no longer use it, but like other CAC products I've used, the CAC Gel Serum has not caused any irritation and has remained comfortable to use. I'm currently pregnant, so I'm also happy that it's fragrance-free. It has a slightly thick, yet refreshing texture that spreads easily, leaving my skin moisturized. It's oil-free, making it easy to use with the rest of the brand's products. I would recommend it to those with sensitive skin!
