Does Having Younger Looking Skin Have Anything To Do With Foods Or Genetics?

Skin is a window to your overall health. The condition and appearance of your skin is an indicator of how well your overall health is. When skin is in good condition, it works hard to protect the body from environmental stressors such as irritants, allergens, and microbes. It also helps to regulate temperature, making it look and feel smooth, calm, hydrated, and even in colour (1).

But, what if it is not in good condition? Is it hormonal in nature? Is it related to food? Is it hereditary? Is it any of these?

 

Yes, it is indeed all of these!

 

Skin that appears younger is closely related to lifestyle and genetics. According to research, there is a gene in the human body that controls our skin condition. Have you ever wondered why certain people of similar age but different appearances appear younger than their actual age while others appear older? The study by dermatologist professor Alexa B. Kimball from Harvard revealed that this has something to do with gene expressions.

 

According to the study, people with rapid gene expression speed up the skin-repairing process when exposed to external or internal stress, which is why they can maintain younger-looking skin. It has also been observed that some people who appear young have rapid gene expression that mimics those who are younger than their chronological age. According to the professor, the skin appears younger because it behaved younger (1)!

 

To elaborate, the one described above is known as intrinsic skin ageing, and it represents chronological ageing, with the same pattern affecting all internal organs. Extrinsic skin ageing, also known as aged skin, is caused by external factors such as environmental influence, particularly chronic sun exposure and ultraviolet (UV) irradiation, but also smoking, pollution, sleep deprivation, and poor nutrition. As a result, when it comes to skin, the best way to avoid harm is to avoid all of these extrinsic factors (1).

 

A study that compared sun-exposed skin (face and forearm) to sun-protected skin (buttock) among women aged 20 to 70 years old discovered that ultraviolet (UV) exposure is a major driver and accelerator of skin ageing. Although sun exposure without any skin protection, such as sunscreen, is harmful to the skin, there is a recommended amount of time spent outdoors without sunscreen so that UVB from the sun can activate vitamin D3 in the skin. The recommended exposure time is 5 - 30 minutes between 10 a.m. and 3 p.m., at least twice a week, to the face, arms, legs, or back (2). In Malaysia, where the weather is sunny all year, excessive sun exposure can cause skin damage. As a result, if one of your 2021 resolutions is to avoid sun damage, you should start wearing sunscreen religiously!

 

Apart from smoking and pollution, which can both cause skin damage, sleep deprivation can also cause skin to appear older. Sleep serves as a reset button for our entire health, including our skin. During sleep, the blood flow to the skin increases, and the organ rebuilds collagen and repairs UV damage, reducing wrinkles and age spots. According to research, sleep deprivation affects wound healing, collagen growth, skin hydration, and skin texture. Inflammation is also higher in sleep-deprived individuals, causing acne outbreaks, eczema, psoriasis, and sin allergies. To combat this, health experts recommend 7 to 9 hours of beauty sleep per day to achieve fluffy baby skin (3,4)!

 

Poor nutrition is also a major contributor to the appearance of older skin, and the worst culprit of all is sugar! Glycation is the process by which sugar interacts with skin. Younger-looking skin is always associated with firm and elastic skin, which refers to the cross-linking structure of skin fibres. This structure can repair itself naturally; however, when sugar is consumed, the glycation process renders the structure and renders the skin unable to remodel into its original structure. As a result, the youthful skin condition has vanished! This explain, sugar consumption is not only bad for metabolic conditions like diabetes mellitus, but also for skin conditions.

 

To summarise, the skin is the largest and most delicate organ; it may appear strong and capable of withstanding all of the external and internal harm that we inflict on it, but it, too, requires pampering. A good skincare routine will help with its condition, but it also requires good food, hydration, and sleep to keep everything in check and balance!
