Product Summary
"May Island - 7 Days Secret 4D Hyaluronic Serum" is effective for: Moisturizing, Anti-aging, Evens skin tone and Anti-blemish
Ingredient callouts
- A good concentration of Niacinamide (1.70% - 2.50%). Niacinamide is a well-studied multi-tasking active. 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 improve the skin tone, reducing pigmentation marks.
- Adenosine 0.10% - 0.50%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
- Humectants (sodium acetylated hyaluronate 0.40% - 0.95%, sodium hyaluronate 0.50% - 1.15%, hydrolyzed collagen 1.30% - 1.90% and glycerin 4.10% - 6.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
With a blend of adenosine and niacinamide to help promote a brighter complexion while reduce the appearance of wrinkles.
Source: Yesstyle
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production

Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycyrrhiza glabra root extract, morus alba bark extract.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Moisturizing
What does the product description say?
7 Days Secret 4D Hyaluronic Serum
Source: From product name
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, hydrolyzed collagen.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, hydrolyzed collagen.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin
