    My Positive Review

    My review: Kiehl’s Powerful-Strength Line-Reducing Concentrate As a 31-year-old man, I have been using Kiehl’s Powerful-Strength Line-Reducing Concentrate for a couple of months now, and I am really satisfied with the results. I started using it to tackle the first fine lines and to generally refresh my skin – and I must say, it has lived up to that. The serum has a pleasant, slightly warming feeling when applied, and the consistency is smooth and easy to spread. It absorbs quickly and doesn’t leave the skin greasy, which I greatly appreciate as someone with a relatively simple skincare routine. After a few weeks of use, I could clearly feel that my skin felt firmer and smoother. The fine lines around my eyes and on my forehead have become less visible, and my skin looks more fresh and healthy. I have also noticed a clearer skin tone and an improved texture, which I did not expect to such a high degree. All in all, it’s a product I intend to keep using. It fits well with my lifestyle, is easy to use, and provides visible results. I can definitely recommend it to other men who want to do a little extra for their skin without overcomplicating their routine.

    Top!

    I've been using it for several weeks now and can feel that my lines have become finer. I will continue to use it. I am participating in a test panel and have received a free test product.

    Review of Kiehl’s Powerful-Strength Line-Reducing Concentrate

    I have been using Kiehl’s Powerful-Strength Line-Reducing Concentrate for a couple of weeks now, and it has become a staple in my routine both morning and night. The first thing you notice is the slightly warm sensation when the serum goes on the skin – not uncomfortable, but a bit surprising at first. You quickly get used to it, and it feels almost like a sign that the product is starting to work. The serum has a creamy consistency that is easy to spread all over the face. It absorbs quickly without being greasy, which I really appreciate – especially in the morning when I need to quickly move on to moisturizer and sunscreen. The scent is fresh and slightly citrusy, but not too overpowering. After a few weeks of use, I feel that my skin looks a bit more even and "happy". I don’t have deep wrinkles, but I can see a difference in my skin’s glow and texture – especially around the mouth and on the forehead, where the skin used to look a bit tired. All in all, a super product if you want to add vitamin C and anti-aging to your routine without too much hassle. I am participating in a test panel and have received a free test product.

    Fantastic product

    I have been using this product for a while now and can see a significant difference. The product dries quickly and doesn't leave a greasy feel, which makes it perfect for applying makeup afterwards. The product smells good, which is a plus. My lines have become much finer and my skin has gotten a beautiful tone that people at work have asked about. I am participating in a test panel and have received a free test product.

    Delicious product

    The product delivers satisfactory results but does not reach the highest standards. Easy to use and you don't need to use much. You can go far with a little. Feels nice and comfortable on the skin. I haven't seen a significant difference in my skin yet, but I like using it and will continue to use the product.

    Nice product

    Received for testing via SMARTSON. I have used the product for about 6 weeks. I experience that the product feels dry when applied to the face and I get a warm sensation on the skin. It doesn't feel uncomfortable and is just a sign that the ingredients are being activated. I don't notice a significant reduction in fine lines, but I do notice that the elasticity in my skin has improved.

    Soft skin

    I have tested it for a month. I think it has a lovely soft consistency that leaves the skin with a thin soft film - just like a primer. I find it hard to say if it has made any difference, but I think it is a good product. I am participating in a test panel and have received a free test product.

    Renewed Glow

    This vitamin C serum has made a noticeable difference for my skin. After a few weeks of use, my skin looks clearer and more radiant. The serum has a light consistency, absorbs quickly, and works well under makeup. I've especially noticed that pigmentation spots and acne scars have become less visible. I use it every morning before moisturizer, and my skin looks healthier and more even. A really good serum, especially for tired and uneven skin that needs a glow. "The review was conducted on behalf of Smartson - the test pilot was allowed to try the product for free."

    Delicious, but

    It’s a delicious product that absorbs quickly and gives a nice feeling on the skin. I have combination skin. Dry on the cheeks but a tendency to oily skin in the T-zone. The product gives me a greater tendency to get oily in the T-zone - especially when I have primer and foundation underneath. So if I were to try it again, I would consider using it only in the evening. I might have combined this product with a cream that could mattify my face a bit.

    Works well

    I have been using the product for a couple of months, and I actually think it has made a difference for my skin. On clean skin, you can clearly feel how something is actively happening when you apply the product, as it gets very warm, and the skin reddens easily. It absorbs quickly and doesn't leave a greasy feel, but I'm not so fond of the faint scent it has. All in all, it's definitely a product that does something for the skin.

    Works, but gets a bit greasy

    I have been using Kiehl's Powerful-Strength Line-Reducing Concentrate for about a month, and I can definitely see that my skin's elasticity has visibly improved and my pores are smaller. All in all, I think the product works, and my only complaint is that I find my skin gets quite greasy and my face shines after 3-4 hours.
