Among the ideas circulating about Vitamin E, this compound is considered effective in combating dark circles. But what is the reality?
Vascular dark circles are characterised by the presence of a concentric circle under the eyes with a bluish or purplish hue, linked to a failure of the blood and lymphatic micro-circulation around the eye contour. The causes of this type of dark circles can be internal and external: lack of sleep, genetic reason, skin ageing.
The brown circles (or pigmented circles) appear as halos present under the eyes of a brown colour, resulting from a hyperpigmentation issue in the area(accumulation of melanin pigments in the superficial layers of the epidermis). They primarily affect individuals with medium to dark skin tones.
The hollow dark circles are V-shaped hollows under the eyes, which can appear black depending on the light. They are caused by a loss of fat between the skin of the lower eyelid and the orbital bone towards the cheekbones, resulting in a loss of volume. The factors are ageing, heredity or even significant weight loss.
Although vitamin E has many benefits for the skin, there is virtually no scientific study that proves its effectiveness in reducing dark circles.
Only a 2004 study concluded that a gel containing 2% phytonadione, 0.1% retinol, and 0.1% vitamins C and E was effective in reducing dark circles and wrinkles on the lower eyelids in adults. However, the amount of vitamin E in this gel was too low and, more importantly, this compound was combined with other active ingredients, making it difficult to discern the effectiveness of vitamin E in reducing dark circles in subjects compared to the other ingredients in the gel.

Dandruff is a persistent condition that affects nearly half the population worldwide. The presence of white or yellow flakes, together with itching and irritation, can be both uncomfortable and frustrating. Recently, glycolic acid, renowned for its use in skincare, has begun to attract attention for its potential role in dandruff management. Could this versatile alpha-hydroxy acid help alleviate the symptoms of dandruff? Let us explore its potential benefits and the scientific rationale underpinning them.
Dark circles under the eyes are a common cosmetic concern. Contributing factors include genetic predisposition, lifestyle choices, skin thinning and hyperpigmentation, all of which can alter the appearance of the under-eye area. A range of treatments exists, from topical agents to cosmetic procedures, with glycolic acid (GA) emerging as a popular chemical peel. But can GA effectively reduce dark circles? This article examines the scientific evidence on the use of glycolic acid for dark circles and its potential benefits.
