Product Summary
"May Island - 7 Days Secret 4D Collagen Cream" is a well-rounded moisturizing product. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Betaine, glycerin, glyceryl acrylate/acrylic acid copolymer, hydrolyzed collagen and sodium hyaluronate in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (ceramide np, hydrolyzed collagen, caprylic/capric triglyceride, cetearyl alcohol and cyclopentasiloxane) 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 love that this moisturizer contains a good concentration of niacinamide 1.90% - 2.30%. Niacinamide is a perfect active in a moistruizer because it helps calm down inflamation in skin and support the skin barrier. More than that, it is helpful for most common skin concerns: it helps regulat oil production, help reduce acne and clogged pores, improve skin tone and prevent pigmentation marks. It also helps fight photodamage.
- As a plus, this moisturizer also contains Ceramides (ceramide np 0.25% - 0.45%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
- Adenosine 0.20% - 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).
- Actives derived from an extract of the Centella Asiatica plant (also known as Gotu Kola) - madecassoside 0.20% - 0.35% The Centella Asiatica Actives, even in low concentration, can help reduce inflammation in skin, strengthen the skin barrier and reduce photodamage. They can also help to decrease scarring.

Anti-aging
What does the product description say?
This collagen cream features 4 Collagen to promote smoother, firmer-looking skin while replenishing hydration with Ceramide, Chinaberry Leaf and Flower Extract, Allantoin.
Source: Yesstyle
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: madecassoside.
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.
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
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)
An antioxidant that is typically derived from plant Centella Asiatica. It can help neutralize free radicals in skin and support skin barrier function. It could, however, itself be irritating. It is often unstable in formulations
Anti-blemish
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.

Anti-oxidation
This product contains antioxidants (madecassoside) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

Evens skin tone
What does the product description say?
Contains Niacinamide and Adenosine to help improve the appearance of fine lines and dull skin tone.
Source: Yesstyle
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: madecassoside.
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 Collagen Cream
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:
betaine, glycerin.
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: ceramide np, madecassoside, niacinamide
Helps attract water to the upper layer of the skin and provide a longer-lasting hydration. Can create a thicker product consistency
