COSRX The 6 Peptide Skin Booster Serum Review

Hi Everyone!

After a long day of migraine, I am back with a new review for you. This time, it is one of my favorite Korean brands. Today is the turn for COSRX, the 6 Peptide Skin Booster Serum. This product is basically a booster and a cocktail of peptides. Why are peptides so important in my skincare? because now it is demonstrated that their help increases the collagen production and improves the skin's appearance and the skin texture. 

COSRX The 6 Peptide Skin Booster Serum

The 6 peptide skin booster contains 6 multi peptides that boost overall skin condition such as pore & sebum, firmness, fine lines, skin texture, skin tone and soothing. It is perfect to use as the first step of skincare routine to prep and boost.

Conclusions

I received this product a couple of months ago, and I started using and my first impression was, this product is liquid and very easy to use. My second impression was that this provides a very moisturizing and luminous effect. The packaging is practical and has a good effect on my skin. I find that this product is absorbed quickly into my skin and doesn´t leave a sticky feeling.

I love the fact that this serum is fragrance-free. But I can notice my skin is smooth and moisturized. The texture is light-weight and watery, and after several weeks, I noticed my skin was luminous. I love how easy it is to use this product. I guess this is a great complement to my skincare routine. This product contains 150 mL, so I am sure I am gonna be using this product for at least 8 months.
