“If your freckles have ceased to be ‘cute’ and are more like brown patches than beauty spots, lighten up with Zelens’s Z Luminous Skin Brightening Serum – a powerful blend of melanin-managing ingredients, which helps to lessen existing dark spots while preventing the development of new ones, so your complexion quickly recovers its youthful clarity.”

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: phenylethyl resorcinol.

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.

NiacinamideKey activeEffect: HighIs 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~5.8–7.1%
Phenylethyl resorcinolKey activeEffect: MediumMight help reduce hyperpigmentation in skin and help neutralize free radicals~1–1.2%

“Infused with a host of potent ingredients, including Hyaluronic Acid, Pearl and Niacinamide, the antioxidant-rich serum melts effortlessly into skin, targeting dark spots and discolouration to leave the complexion clearer, brighter and younger-looking.”

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

What the product description says
“Smoothing, hydrating and revitalising, this cocktail of radiance-boosting active ingredients – including cell-energising niacinamide to counteract pigmentation and blotchiness, zinc-glycine complex to reduce melanocyte proliferation and melanin production, and phytic acid, which exhibits a mild exfoliating action to accelerate the cell-renewal process – will quickly recapture your skin’s youthful lustre.”

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: 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: caprylic/capric triglyceride, dimethicone.

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

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
