Glycation refers to the process of how our body handles excess sugars.
At its core, glycation is a non-enzymatic reaction that occurs when sugar molecules in the bloodstream bond to proteins like collagen and elastin. These proteins are responsible for keeping our skin bouncy and youthful. When glycation takes hold, it compromises the protein structure of these essential fibres.
The result of this bonding is the formation of AGEs (Advanced Glycation End products). These glycation end products are harmful compounds that cause collagen to become stiff, brittle, and discoloured. Because collagen is one of the most abundant proteins in the body, the development of these glycation end products leads directly to the visible sagging and deep wrinkles we associate with getting older.
Glycation and its subsequent oxidative stress and inflammation further accelerate the breakdown of the skin matrix.
While glycation occurs naturally in the body as we age, a diet high in sugar can speed up the formation of AGEs. Furthermore, UV exposure acts as a catalyst, significantly increasing the accumulation of AGEs in the dermis. This makes glycation one of the primary culprits behind premature skin damage in sunny climates.
Fortunately, understanding that glycation is somewhat preventable allows us to take action. While it is difficult to completely stop glycation, an effective anti glycation strategy can slow down the process significantly.
The first line of defence is managing your internal sugar molecules. High blood sugar levels lead to insulin resistance, which creates a “syrup-like” environment in your bloodstream that is perfect for the formation of AGEs. In Singapore, many of our beloved local staples are high-glycemic index (GI) foods that cause these rapid spikes. To protect your collagen, it is vital to reduce your intake of:
However, internal changes alone may not be enough. Incorporating high-performance skincare products into your skincare routine is essential to reduce the impact of glycation end products that have already formed.
According to the Health Promotion Board (HPB) and the World Health Organization (WHO), added sugar should make up less than 10% of your daily caloric intake. For the average adult, that is approximately 40g to 55g (about 8 to 11 teaspoons).
However, if your goal is strictly anti glycation and preventing wrinkles, the “safe” threshold is even tighter.
To put those “10 teaspoons” into perspective, here is how quickly a typical day in Singapore can trigger the glycation process:
Item | Est. Sugar Content | % of Daily Limit |
|---|---|---|
Kopi / Teh | ~4-5 teaspoons | 50% |
Bubble Tea (100% sugar) | ~18-20 teaspoons | 200% |
Mee Siam / Mee Rebus | ~2-4 teaspoons | 30% |
Can of Soft Drink | ~7-9 teaspoons | 80% |
If you want to protect your protein structure while still enjoying life in Singapore, try these “hacks” to reduce the formation of AGEs:
The “Siu Dai” or “Kosong” Rule: Simply switching your daily Kopi or Teh to “Siu Dai” (less sugar) or “Kosong” (no sugar) can reduce your skin’s sugar exposure by over 1,500g a year.
The Order of Eating: Eat your fiber (vegetables) and protein (meat/tofu) before your carbohydrates (rice/noodles). This slows down the absorption of sugars and prevents the massive insulin spike that triggers glycation.
Vinegar or Lemon: Adding an acidic element like lime (common in Mee Siam or Hokkien Mee) can help lower the glycemic response of the meal, protecting your skin from immediate oxidative stress.
To effectively combat the formation of AGEs, we recommend a dual approach involving professional skincare products and targeted treatments.
SkinCeuticals offers the A.G.E. Interrupter Advanced, which is a potent anti glycation cream specifically formulated to reduce the visible signs of glycation and ageing. It works by protecting the skin from the development of new glycation end products while smoothing existing wrinkles.
For those seeking a more intensive result, our SkinCeuticals+ Tri-Action Anti-Glycation Treatment is designed to target the glycation cycle. This rejuvenating treatment focuses on using specialised techniques and products to revitalise collagen fibres and to clear the skin of impurities, making skin appear more youthful and supple.
Is glycation something you can ignore? Given that glycation is a leading cause of skin structural failure, the answer is a firm no. By understanding what is glycation, and how glycation end products interact with amino acids and proteins, you can make better choices for your skin health today.
Glycation is a non-enzymatic chemical reaction that occurs when excess sugar molecules in the bloodstream bond to skin proteins like collagen and elastin. This process leads to the formation of Advanced Glycation End products (AGEs), which cause these structural fibres to become stiff, brittle, and discoloured.
Because collagen and elastin are responsible for skin firmness and elasticity, the accumulation of glycation end products directly results in “sugar sag,” characterised by deep wrinkles, a sallow complexion, and a loss of facial volume.
While glycation is largely an irreversible process once the cross-links in the collagen have formed, an effective anti glycation strategy can significantly slow its progression and improve the skin’s appearance.
Using skincare products specifically formulated to interfere with the glycation cycle (such as SkinCeuticals A.G.E. Interrupter Advanced) helps to protect existing fibres from further damage. Additionally, managing blood sugar levels and reducing oxidative stress through a low-glycemic diet can prevent the formation of new AGEs, allowing the skin to maintain better skin elasticity over time.
The most effective anti glycation strategies involve a combination of internal dietary management and external topical treatments. Internally, reducing the intake of high-glycemic foods and “Siu Dai” beverages prevents the insulin spikes that trigger glycation. Externally, incorporating a high-potency antioxidant and a dedicated anti glycation cream into your skincare routine protects the skin barrier from environmental catalysts like UV exposure.
For more intensive results, professional services such as the SkinCeuticals+ Tri-Action Anti-Glycation Treatment target the glycation end products within the dermis to revitalise the protein structure of the skin.
