While consuming excess sugar can lead to weight gain, type 2 diabetes, and tooth decay, it can also impact your skin and accelerate the signs of ageing.

Sugar speeds up skin ageing by causing glycation which harms collagen and elastin.

Consuming too much sugar leads to certain health problems like weight gain, type 2 diabetes, heart issues, tooth decay and others. But did you know it can actually leave a lasting impact on your skin and affect how our skin ages? Dr Astha Jani, a maxillofacial and cosmetic surgeon, is popular among her followers on Instagram for sharing wellness insights and guiding her followers to take the right steps.

Earlier, Dr Astha took to Instagram to reveal the evils of consuming excess sugar and how it affects one’s skin. In the post, she explained that when someone consumes an excessive amount of sugar, it combines with proteins like collagen and elastin through the glycation process, which ultimately weakens essential proteins and leaves the skin stiff and fragile, making it prone to wrinkles. By damaging collagen and elastin, the two essential factors that maintain firmness and skin elasticity, glycation results in dullness and sagging skin.

Sharing the post, Dr Astha wrote, “Excess sugar in your diet triggers a process called glycation, where sugar molecules stick to collagen and elastin proteins, making your skin stiff, dull, and prone to wrinkles. Sweet today, saggy tomorrow!” She further explained that high sugar consumption promotes inflammation, which contributes to redness, uneven skin tone, and, at times, excessive breakouts. Inflammation also triggers the skin to age faster than normal. Moreover, excess sugar intake may make your skin vulnerable to UV rays, leading you to face dark spots and loss of natural skin glow.

Alongside explaining the evils of excess sugar consumption, she also provided ways on how you can cut sugar consumption and save your skin. She urged her followers to include antioxidant-rich foods in their diet, such as berries, nuts, and green vegetables, to rejuvenate their skin. She also advised staying hydrated throughout the day and applying sunscreen daily. She also made it clear that although consuming excessive sugar is dangerous to one’s health and skin, she advised sticking to complex carbs like whole grains, fruits, and legumes over consuming refined sugar.
