Understanding the Science of Skin Ageing

Ageing is a natural process, but let’s be honest—we all want to slow it down. As we get older, our skin starts losing collagen and elastin, two key proteins that keep it firm and bouncy. Over time, fine lines, wrinkles, and sagging appear, making our skin look less youthful.

It’s not just time that affects our skin. Factors like sun exposure, pollution, stress, poor diet, and inflammation speed up the ageing process. That’s why taking care of your skin from the inside out is just as important as what you put on it.

Can You Prevent Skin Ageing?

You can’t stop time, but you can slow down how it affects your skin. Protecting your skin from UV rays, eating a nutrient-rich diet, reducing stress, and staying hydrated all help keep your skin looking youthful. But let’s be real—life happens, and sometimes we need extra support. That’s where supplements come in.

The Best Supplements for Ageing Skin (and Why Gut Health Matters)

Not all supplements are created equal. But one thing many people overlook is that the effectiveness of these supplements depends on a healthy gut barrier. If your gut isn't functioning properly, your body won’t absorb key nutrients efficiently—meaning you won’t get the full benefits of collagen, vitamins, or antioxidants for your skin.

1. Collagen Peptides

Collagen is like the scaffolding of your skin—without it, skin loses firmness. Taking a collagen supplement provides the building blocks your body needs to produce more collagen, leading to smoother, plumper skin. However, if your gut barrier is compromised, collagen peptides may not be absorbed properly, reducing their effectiveness.

2. Vitamin C

Vitamin C isn’t just great for immunity—it’s a powerhouse for skin. It helps your body produce collagen, brightens the complexion, and fights oxidative stress that leads to premature ageing. A strong gut barrier ensures optimal absorption of vitamin C, making it more effective.

3. Vitamin E

Known for its moisturising and healing properties, vitamin E helps protect skin from damage caused by UV rays and free radicals. But if your gut is inflamed, it can impair the absorption of fat-soluble vitamins like vitamin E.

4. Curcumin (from Turmeric)

Curcumin is a natural anti-inflammatory that helps calm stressed-out skin and may even support collagen production. Since curcumin has low bioavailability, a healthy gut barrier is essential to ensure maximum absorption.

5. Resveratrol

Found in grapes and red wine, resveratrol is packed with antioxidants that protect skin from environmental stress and ageing. An intact gut barrier helps your body absorb resveratrol more efficiently.

6. Postbiotics and Gut-Skin Health

This might surprise you, but your gut health has a direct impact on your skin. A healthy gut barrier reduces inflammation and helps nutrients absorb better, leading to a healthier, more radiant complexion. Postbiotics, which strengthen the gut barrier, help ensure that skin-supporting nutrients are properly absorbed and used by the body.

The Gut-Skin Connection: Why It Matters More Than You Think

Your gut and skin are more connected than you think. This link, known as the gut-skin axis, means that what’s happening in your gut often shows up on your skin. But this isn’t just about gut microbiota—it’s about gut barrier integrity. If your gut barrier is compromised (also known as “leaky gut”), it can lead to chronic inflammation, which accelerates skin ageing.

What can you do?

1) Eat fibre-rich foods to support a healthy gut barrier.

2) Take supplements with prebiotics, probiotics, and postbiotics to maintain gut integrity.

3) Reduce inflammation by avoiding processed foods and excessive sugar.

4) Use products that combine postbiotics with skin-loving ingredients to improve skin health from within.

Choosing the Best Supplement for Ageing Skin

There are countless supplements on the market, but not all are created equal. To find one that truly supports skin health and ageing from within, look for products that meet the following criteria:

Science-backed Ingredients: Choose supplements developed with strong scientific foundations. Y SKIN is informed by decades of research, including our own published work on inflammation and hormonal balance, as well as our latest findings on postbiotics’ effects on skin structure and appearance—currently under peer review.

Gut Health Support: A healthy gut barrier is essential for effective nutrient absorption. Supplements that support gut integrity—like Y SKIN—help your body get the most out of skin-loving nutrients such as collagen, antioxidants, and vitamins, while also reducing inflammation that contributes to skin ageing.

Sustained Results: Unlike topical treatments that offer quick but temporary fixes, skin-focused supplements work gradually from within. With consistent use over 2–3 months, you should notice improved hydration, elasticity, and an overall healthier, more radiant complexion.

How to Tell If Your Skin Supplements Are Working 

Unlike face creams that give instant hydration, supplements take time to show results. Here’s what to expect:

• After 2-3 weeks: Skin feels more hydrated and plump.

• After 4-6 weeks: Fine lines appear softer, and your skin looks healthier.

• After 2-3 months: Improved elasticity, a more radiant glow, and smoother texture.

Consistency is key—stick with it, and your skin will thank you!

Final Thoughts on Ageing Skin 

Ageing is inevitable, but how your skin ages is within your control. By focusing on nutrition, gut barrier health, and targeted supplements, you can maintain a youthful glow for longer.

Your gut health plays a huge role in your skin’s appearance—so if you want healthy, glowing skin, start from within. 

Frequently Asked Questions

Do collagen supplements really work?

Yes! But their effectiveness depends on proper digestion and absorption. A healthy gut barrier ensures your body can break down and use collagen efficiently.

How does gut health affect my skin?

Your gut barrier controls what enters your bloodstream. A weak gut barrier allows inflammation to spread, which can accelerate skin ageing. Strengthening it helps nutrients reach your skin more effectively.

What’s the best supplement for glowing skin?

A combination of collagen, vitamin C, postbiotics, and antioxidants works best to keep skin youthful and radiant.

How long does it take for skin supplements to show results?

Most people see improvements in hydration and glow within a few weeks, while deeper benefits like elasticity and fine-line reduction take around 2-3 months.

Why should I choose a supplement that supports gut barrier health?

A strong gut barrier is essential not just for getting the most out of skin supplements, but also for absorbing key nutrients from your everyday diet. Postbiotics help reinforce the gut barrier, ensuring your body can efficiently utilise these nutrients for healthier skin and overall well-being.
