Product summary
Judging from the ingredient list, "Secret Key - MAYU Healing Facial Cream" works well for improving skin hydration 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. Humectants in this product (glycerin, sodium hyaluronate, honey extract 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 (ceramide np, hippophae rhamnoides oil, butyrospermum parkii butter, caprylic/capric triglyceride and dimethicone) 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 1.70% - 2.10%. 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 0.25% - 0.45% in this product adds an anti-aging property to it. Adenosine is a chemical present inside our skin cells. A clinical trial confirmed that topical application of adenosine in a low concentration reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where we our mimic is the most active, for example, in the corners of the eyes or on the forehead).

Price
The product retails from 18.90$ up to 26.00$ in the United States.
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, sodium hyaluronate.
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:
butyrospermum parkii butter, caprylic/capric triglyceride.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: ceramide np, niacinamide
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
A type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin

Anti-blemish
This product might be able to help reduce blemishes and clogged pores because it contains niacinamide.
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.

Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
Anti-aging
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.

Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following
effective ingredients:
