WIMJ summary

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: lactic 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: betaine salicylate, glycolic acid, lactic acid

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?
"Combining BHA and Black Bee Propolis, the toner effortlessly melts dirt and dead skin cells from the surface of the skin."
WIMJ summary

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: betaine salicylate, glycolic acid, lactic acid.

What does the product description say?
"Without stripping the skin of moisture, the formula provides an additional cleanse after face wash, which leaves the face ultra-clear and refreshed."
WIMJ summary

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": allantoin, lactic acid.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

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