How Does REN Dark Circle Eye Cream Work?

REN Radiance Brightening Dark Circle Eye Cream claims to target dark circles and puffiness through a combination of 95% naturally derived ingredients. The formula is designed to be gentle on the delicate under-eye area while delivering hydration and protection.

One key ingredient, glycogen, is claimed to improve skin hydration. This ingredient may plump and smooth the under-eye area. Glycogen also enhances moisture retention in the skin through enhancement of ceramide production, thereby promoting a healthier appearance. Elderberry flower extract is rich in antioxidants and works to calm and protect the delicate under-eye skin from oxidative stress.

The product also uses extracts derived from plant sources to brighten pigmentation and support an even skin tone. While the formula is promising, its effectiveness depends on consistent use and individual skin types.

REN Dark Circle Eye Cream Ingredients – Are They Safe & Effective?

Here are some of the key ingredients in REN Dark Circle Eye Cream:

Glycerin

Glycerin is a powerful humectant that attracts moisture to the skin. It is a plant-derived ingredient that helps to keep the under-eye area hydrated and plump. A 2022 study in Scientific Reports highlights the effectiveness of glycerin in keeping skin smooth and hydrated.

Glycogen

Glycogen is a natural moisture-retaining ingredient that helps plump the skin and reduce the appearance of fine lines. It supports the skin’s barrier function and improves hydration. A study published in the Journal of Applied Glycoscience highlights the ability of glycogen to prevent water loss and protect the skin against environmental stressors.

Hiroko Yatsuhashi and other researchers at the Institute of Health Sciences, Ezaki Glico Co., mention in their research, Accordingly, we propose that glycogen might be effective for maintaining skin health through the enhancement of ceramide production.

Elderberry Flower Extract

Elderberry flower extract is rich in antioxidants and has anti-inflammatory properties. It neutralizes free radicals and soothes the under-eye area, reducing puffiness and irritation.

A research study published in Molecules supports its role in protecting skin from oxidative damage, making it ideal for sensitive, tired eyes. Also, our review of Black Sambucus Elderberry Review (another product containing the ingredient) suggests it can help strengthen the immune system and reduce inflammation

Shea Butter Ethyl Esters

Shea butter ethyl esters provide lightweight yet effective hydration, nourishing the delicate under-eye area without clogging pores. According to research published in the International Journal of Molecular Sciences, shea butter supports skin barrier function and reduces dryness.

Sodium Hyaluronate
