A friend recommended this to me, so I tried it! The first time I used it, I was amazed at how quickly it penetrated my dry skin. It absorbed quickly into my skin, which made it easy to apply my next skincare routine (lotion, cream, etc.), which was great!
I received this serum as part of a Coetas campaign and am using it. It's a luxurious blend of high-concentration vitamin C glucoside, high-concentration placenta extract, human stem cell extract, exosomes, and sodium hyaluronate. Apply an appropriate amount (5-8 drops) to your skin immediately after cleansing. Its smooth, watery texture feels like it penetrates deep into your skin (all the way to the stratum corneum), creating a pleasant sensation. Gently pressing it into your hands leaves a non-sticky, yet still soft, texture. It's non-irritating and almost fragrance-free, so it pairs well with other skincare products (all personal impressions). With continued use, my skin feels softer (pores appear plumper and less noticeable), and my next skincare product seems to work better. (^^) It's fragrance-free, colorant-free, paraben-free, and UV-absorber-free. It's a must-have addition to your daily skincare routine for those concerned with dullness, pore size, and firmness. #DLSerum #Exosomes #PlacentaExtract
I bought this product after being recommended it by the owner of a beauty salon. I noticed results after just three days of use! My pores are less noticeable and my makeup goes on so well! I've been using it for a year now, and my skin tone has brightened so much that I've switched to a lighter foundation. I think this is amazing!
Diffstory's ultimate serum, finally perfected after years of research, is Diffstory's #1 best-selling item, DL Serum (Concentrated Serum). This concentrated serum contains placenta, vitamin C, two types of human stem cells, and hyaluronic acid, resulting in a translucent, beautiful complexion. It's recommended for combating dullness in adults. Use this concentrated serum at the beginning of your skincare routine after cleansing. Simply apply 5-8 drops to the palm of your hand and massage it into your entire face. Its smooth texture blends easily into your skin. It's non-greasy and won't interfere with subsequent skincare routines. We recommend storing it in the refrigerator after opening. Recommended for treating skin damaged by UV rays! Perfect for the coming season.
I was told to store it in the refrigerator after opening! I have a tendency to get acne, but since I started using this, my skin irritation has really decreased!! I really like it (^^)
