How are pain sensations produced by the body?
Pain can be caused by a myriad of factors and nociceptors are differentiated based on the type of stimuli that they detect. These include thermal, mechanical, and chemical. Silent pain receptors are activated when there is any inflammation or tissue injuries. Following exposure to harmful stimuli (e.g. heat, incisions that break the skin’s surface, corrosive chemicals, etc.), tissues become damaged and appropriate pain receptors get activated. Electrical signals are then generated and propagated along the nerve cells to the spinal cord and the brain for processing. These pain sensations will then quickly alert the body of dangerous situations and prevent further ...
What is hyaluronic acid for the skin?
Hyaluronic acid (HA) is an intricately shaped carbohydrate molecule found in abundant quantity in the human body. Its main function is to deliver moisture and nourishment to other cells for optimal functionality. This hydrating cell was first isolated from vitreous humour—the jelly-like substance—of cow eyes by 2 scientists from Columbia University, Karl Meyer and John Palmer. With further research, hyaluronic acid was proven to be an excellent humectant that draws moisture to the skin from the surroundings. Since its skincare benefits are aplenty, HA is now available in various forms, from lightweight hydrating facial mist to hydrating cream.

What is an under-eye hollow?
The under-eye area—also known as the tear trough—is the region extending downwards and outwards from the inner corner of the eye. The skin in this region is very delicate as it consists of a very thin layer of skin at just <1mm. The under-eye region has a high tendency to develop premature ageing signs like fine lines, darkness, puffiness, and hollowness. Under-eye hollows develop when fat pads under the eyes and around the upper cheek area are depleted due to ageing or even weight loss. The absence of fat pads makes the underlying muscles and vast network of blood vessels very prominent, resulting in unsightly under-eye shadows. If left uncorrected, patients with extreme under eye hollows may look gaunt or older than their chronological age.
