WIMJ summary

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

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.

What does the product description say?

"PHA Moisture Renewal Power Cream"

From product name

WIMJ summary

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: allantoin, betaine.

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: beeswax, caprylic/capric triglyceride.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

WIMJ summary

This product contains antioxidants (gluconolactone) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Ingredients by volume

Ingredient	Estimated concentration
cocos nucifera fruit extract An emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic	22% - 33%
butylene glycol Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin	5.5% - 8.2%
glycerin One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant	4.4% - 6.5%
caprylic/capric triglyceride 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	4% - 5.9%
helianthus annuus seed oil A great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function	3% - 4.5%
cetearyl alcohol A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture	2.2% - 3.3%
gluconolactone A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals	1.6% - 2.4%
