Sugar may be a quick source of comfort and pleasure, but its long-term impact on the body especially the skin is far from sweet. Nutritionist Nmami Agarwal has cautioned that regular overconsumption of sugar can silently undermine skin health, accelerating ageing and triggering multiple skin-related problems. In a recent Instagram post, she explained how sugar works from within the body to weaken the skin’s natural strength and glow.
According to health and nutrition experts, the effects of sugar go much deeper than surface-level breakouts. Over time, high sugar intake alters internal biological processes that are essential for maintaining youthful, healthy skin. From fine lines and wrinkles to chronic inflammation and acne, the damage often builds gradually and becomes visible sooner than expected.
One of the most harmful ways sugar affects the skin is through a process known as glycation. This occurs when excess sugar in the bloodstream attaches itself to vital proteins such as collagen and elastin, which are responsible for keeping the skin firm, smooth, and flexible. Once sugar binds to these proteins, it forms harmful compounds called advanced glycation end products, or AGEs. These compounds weaken collagen and elastin, making the skin lose its elasticity and resilience. As a result, sagging skin, fine lines, and wrinkles begin to appear earlier. While glycation is a natural part of ageing, a sugar-heavy diet significantly speeds up this process. Beyond skin damage, AGEs can also harm blood vessels and nerves, increasing the risk of serious conditions such as heart disease, stroke, and neurological disorders.
Another major concern linked to high sugar intake is inflammation. Sugar stimulates the release of pro-inflammatory chemicals in the body, known as cytokines. These substances promote internal inflammation, which directly affects skin health. Chronic inflammation breaks down collagen and elastin, further contributing to wrinkles and loss of firmness. It also worsens existing skin conditions such as acne, rosacea, and eczema. People who consume excessive sugar may notice frequent breakouts, redness, irritation, and uneven skin texture, even if they follow a regular skincare routine.
Excess sugar consumption also disrupts hormonal balance by increasing the risk of insulin resistance. Insulin is the hormone that regulates blood sugar levels, and when the body becomes resistant to it, insulin levels rise. This hormonal imbalance can trigger multiple skin issues. Increased insulin can stimulate excess oil production, leading to clogged pores and acne. It may also contribute to conditions such as hirsutism, which involves unwanted facial or body hair, and melasma, marked by dark patches on the skin. Insulin resistance is not just a skin concern it is closely linked to long-term health problems including type 2 diabetes, cardiovascular disease, and stroke.
The message from experts is clear: cutting back on sugar is not just beneficial for overall health, but also crucial for maintaining youthful, healthy skin. Reducing sugary foods and beverages can slow premature ageing, minimize inflammation, and lower the risk of chronic diseases. A balanced diet rich in whole foods, fruits, vegetables, healthy fats, and adequate protein supports skin repair from within and helps preserve its natural glow over time.
