Ksecret SEOUL 1988 Eye Cream : Retinal Liposome 4% + Fermented Bean

Based on the ingredient list, "Ksecret - SEOUL 1988 Eye Cream: Retinal Liposome 4% + Fermented Bean" can work well for skin moisturization. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (glycerin, sodium hyaluronate and butylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (cholesterol, caprylic/capric triglyceride, brassica campestris sterols, butylene glycol dicaprylate/dicaprate and cetearyl alcohol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

• We particularly like that there is a good concentration of Niacinamide (1.40% - 2.10%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and help improve the skin tone, reducing pigmentation marks.
• This moisturizer contains Bakuchiol (0.10% - 0.45%). It is a plant extract that is has a similar effect to that of Retinoids but with less irritation. Bakuchiol can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation.
• This moisturizer contains an effective form of Retinoids (vitamin A): retinal 0.05% - 0.30%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily. Because of the irritation risk of Retinoids, we recommend to have another, retinoid-free moisturizer in your routine to use on the alternate days or when your skin feels dry.
• We like that this moisturizer contains peptides (sh-polypeptide-1 0.05% - 0.20%, sh-oligopeptide-2 0.05% - 0.20% and sh-oligopeptide-1 0.10% - 0.35%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
• Adenosine 0.10% - 0.35%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
