I normally use Lancôme serums, but using them morning and night is too cost-effective, so I was looking for a serum that would moisturize and prevent rough skin during the day, and I found this one. First of all, the texture is a dense gel that blends in beautifully with the skin. The recommended amount is one pump, but I apply one pump and then half a pump on my cheeks. My biggest issue is dryness, which causes sebum breakdown, but even when I work in an environment with large temperature swings during the day, my skin doesn't feel tight and I can stay comfortable. This is a serum that I'm very satisfied with at this price. I'm happy that I haven't had any small breakouts. I plan to buy a refill again.
I apply it after taking a bath. I apply it in the following order: lotion → serum → emulsion, and it's amazing... Before, I didn't feel like the emulsion after the serum was absorbed very well, but this one adheres firmly and feels like it's sealed in, and my skin, which was rough from being exposed to the winter air, is now moisturized. My skin feels calmer and more at ease.
I've been feeling particularly dry this winter, partly due to the effects of the medication I'm taking, so I decided to try this product. Since I'm also taking medication, I chose this product because it's gentle and readily available. I've used d Program products before, so I felt comfortable choosing it. It's a thick, watery liquid. It absorbs quickly, isn't sticky, and doesn't leave a greasy, oily feeling. It's gentle and easy to use, both in the morning before makeup application and as part of my evening skincare routine. Since it's originally a brand for sensitive skin, the results aren't immediately noticeable, but I think it's a product that's easy to continue using regardless of skin condition. The only drawbacks are that it wears off surprisingly quickly, and the effects felt a little gradual on my skin. However, this is definitely a product and brand I'll continue to use when my skin is in an unstable condition.
I use it together with the lotion. The lotion alone is moisturizing, but adding this serum makes my skin feel denser. It feels sticky right after application, but over time I can feel it moisturizing from the inside. It's an essential product for combating dry winter skin!
My dry skin irritation (redness on my eyelids, redness and dryness on both cheeks) just wasn't improving with my usual skincare routine (ceramide-based cosmetics), so I bought this product based on the ingredients and reviews. I also started taking a ceramide supplement again, which had helped me with dry skin in the winter, and switched to a lotion for sensitive skin, so I'm not sure which one was the most effective. However, this product caused no irritation to my dry skin. As I write this review, I'm truly relieved that the redness in the less oily areas of my face and the dryness on my cheeks, which used to make me sad every time I looked in the mirror, have completely improved. The only problem I had was that the lid was slippery and difficult to open, partly because I was rubbing the lotion in with my hands, but I liked the pale pink, round shape and the refill, which is the same volume as the main product.
