Why is Collagen Essential for Your Skin?

The gradual process of aging starts from the inside. Aging causes a natural degradation of the skin’s processes, leading to signs of aging.

Aging does not start from the surface of the skin. Even before they become visible on the surface, the aging process has already begun deep inside the skin. 

The first visible signs of aging can appear in as early as mid-20s, as fine lines and wrinkles start to appear around the eyes and mouth. They often appear in the form of crow’s feet and drooping of the eyelids. Over time, fine lines also begin to form around the forehead and upper lip.

As we age, the body starts to produce less collagen over time. Collagen is the key protein in the skin that serves as a structural building block to keep the skin firm and supple, giving rise to healthy-looking skin.

What is collagen?

Collagen is a hard, fibrous protein that makes up one-third of all proteins in the human body. Most collagens are packed together to form long, thin fibrils that act as supporting structures and hold cells together. They give the skin strength and elasticity, which is commonly associated with younger people.


Collagen is mainly secreted by connective tissue cells. 

In particular, collagen helps to form a fibrous network of cells called fibroblasts in the dermis, encouraging new cells to grow. At the same time, it also plays the role in generating and replacing skin cells.

Our body functions generally slow down when we age. Collagen production also slows down in the body, compromising the structural integrity of the skin, causing wrinkles to form and joints to weaken.

Collagen can be broken down, converted, and absorbed back into the body. Scientists have found that collagen can also be compacted into a gel-like form. This unique nature of the protein has allowed doctors to create a diverse range of treatments that involves administering collagen to localized areas of the body for various medical purposes.

How to increase collagen levels

Boosting and restoring the level of collagen can be an uphill battle. Most people often turn to skincare products and supplements to boost collagen production. Unfortunately, these are not effective and do not directly stimulate the production of collagen in the skin.

Some medical treatments provide an immediate improvement by stimulating the body to produce collagen so that the skin remains firm and supple. 


Ultherapy is a non-surgical, non-invasive procedure that uses high intensity focused ultrasound to lift and tone saggy skin on the face, particularly on the brow, neck, chin, and décolletage.

It works by bypassing the superficial layers of the skin to deliver ultrasound energy at controlled depths at the right, consistent temperature. By heating the tissue to about 60-70°C, it triggers the skin to stimulate new collagen growth, as it has been proven that collagen growth occurs at around that temperature. 

Collagen dermal fillers

Collagen dermal fillers work in two ways – Improve the contours of the skin by filling out depressions and stimulate collagen by creating fibroblasts. 

Collagen fillers such as Radiesse and Ellanse can be used cosmetically to smooth out lines and wrinkles on the face immediately. At the same time, the contents in these filler injections help to establish a scaffold under the skin and work with your body to revitalize collagen production.

Rejuran Healer

Hailing from Korea, Rejuran Healer is made of polynucleotide from salmon. This injectable treatment assists with tissue repair and promotes the production of collagen for skin rejuvenation.

It induces fibroblasts production necessary for the stimulation of collagen. In addition, it creates a natural result in improving skin laxity, enlarged pores, and fine lines.

INFINI micro-needling

Micro-needling technology coupled with radiofrequency waves is another option doctors commonly recommend to stimulate dermal collagen with precision and reach deeper for a more customized treatment.

By bypassing the superficial layers of the sin, INFINI laser administers radiofrequency energy directly into the dermis to trigger the skin’s natural healing process and kickstart collagen remodelling. 

Do collagen skincare products work?

Many off-the-shelf skincare products claim to contain collagen. They claim to revitalize the skin by increasing collagen levels within the body.

This is highly unlikely because collagen molecules are generally large and they cannot be absorbed through the skin. 

If you notice any visible reduction of wrinkles and fine lines after applying a layer of so-called collagen cream, it is probably due to the moisturizing effects that temporarily plump up the skin. They do not directly increase collagen production.

The earlier you take active steps to slow down the aging process and maintain a healthy level of collagen in your skin, the more delayed the onset of aging, making you look younger than you really are.
