WIMJ summary

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: 3-o-ethyl ascorbic acid.

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.

WIMJ summary

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: 3-o-ethyl ascorbic acid, 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.

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.

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: 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: dimethicone, caprylyl glycol.

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

Ingredients by volume

Ingredient Estimated concentration
Plain old water
45% - 55%
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
4.5% - 5.6%
Used to add a nice rose smell to the product. Can be irritating
4% - 4.9%
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
3% - 3.7%
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
2.4% - 2.9%
Used to create a nice product consistency
1.9% - 2.3%
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
1.6% - 1.9%
Helps water and oil mix together and create gel-like textures
1.4% - 1.7%
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products

The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging
0.9% - 1.1%
Helps preserve products and creates a nice product texture
0.7% - 1%
A cactus extract that can help neutralize free radicals because it contains a chemical compound called betacyanins and flavonolglycosides. Can help make the surface of the skin dryer helping make pores look smaller for a very short period of time. The concentrations usually used in cosmetics are too small to have any effect
0.55% - 0.8%
