Torriden Dive In Low Molecular Hyaluronic Acid Serum is a product that densely replenishes moisture from deep within using 5D complex hyaluronic acid, allowing you to feel hydration plumping up from the inside out without any tightness. It provides 48 hours of lasting hydration with just a single application, and the addition of panthenol and allantoin enables intensive hydration and soothing care. As someone who constantly searches for the perfect toner/serum combination in my skincare routine, I have tried many different products; I purchased the Torriden Dive In Low Molecular Hyaluronic Acid Serum because it has great ingredients and is the best value for the price. I have combination skin that is prone to dehydration; specifically, my T-zone is oily while my cheeks and chin are dry, making basic skincare very tricky in both summer and winter. In the summer, I sweat a lot and my skin becomes very oily, so applying multiple products feels stifling. However, Torriden Dive In products are lightweight and non-sticky, making them ideal for summer use. Perhaps because the ingredients in the Torriden Dive-in line are gentle, I didn't experience any breakouts after applying it. It is a decent serum that is great to use before lotion. The texture is watery and moisturizing; if you apply a generous amount to your face and gently pat it in, it absorbs quickly. I heard that using the wrong serum can cause blemishes, but I haven't experienced any so far. This product is very reliable and affordable, so I am using it to my heart's content. It is a must-have item. It is a serum that can be used as a basic skincare routine in both hot summers and cold winters. I highly recommend it!
