The Healthy Men’s Skin Guide: How to support ageing skin naturally

Your skin, hair and nails say more about your health than you might realise, and the real secret to keeping them in good shape has nothing to do with what’s on your bathroom shelf. We’ll break down exactly what’s happening to your skin as you age, the nutrients that make the biggest difference and the simple steps you can take to look and feel better from the inside out.

Why should men care about their skin as they age?

Let’s be honest. Most men don’t give their skin a second thought until something changes. A few more lines around the eyes. Hair that’s looking a little thinner on top. Nails that seem to break more than they used to. Sound familiar?

Here’s the thing. Your skin is the largest organ in your body. It’s also one of the most honest. It reflects what’s happening on the inside, whether that’s poor nutrition, chronic stress, too many late nights or simply the passing of time. And for men, the changes tend to creep up quietly, then seem to arrive all at once.

The good news? A lot of it is within your control.

What actually happens to your skin as you get older?

From your mid-thirties onwards, your skin starts to change in ways you might not immediately notice. Collagen production begins to slow. Skin becomes a little less firm, a little less bouncy. Cell turnover, the process that keeps skin looking fresh, gradually loses its pace.

Men do have a slight advantage here. Male skin is naturally thicker than female skin, with higher collagen density. This means visible ageing often appears later. But when it does show up, it tends to be more pronounced.

Sun damage from years of skipping SPF. Coarser texture. Deeper lines. And for many men, thinning hair and brittle nails arrive around the same time.

However, diet, lifestyle and nutritional gaps play a huge role. And that means there’s plenty you can do about it.

What’s really going on under the surface?

You might think of skin ageing as something that just happens. A few wrinkles here, some sagging there. But a lot is going on beneath the surface that drives those visible changes. And once you understand it, you can actually do something about it.

Why do men lose collagen, and what does that mean for your skin?

Collagen is the protein that gives your skin its structure and firmness. Think of it like the scaffolding that holds everything in place. When it’s plentiful, skin looks taut, smooth and healthy. When it starts to break down, things begin to shift.

Men produce more collagen than women on average, which is why male skin tends to age a little later. But here’s the catch. Collagen production still declines by roughly 1% per year from your mid-twenties onwards. By the time you’re in your forties, that loss starts to become visible.

UV exposure speeds the process up significantly. So do smoking, excess sugar and chronic stress, all of which trigger enzymes that actively break collagen down. It’s not just time doing the damage.

How do hormonal changes affect your skin as you age?

Testosterone plays a bigger role in skin health than most men realise. It stimulates collagen production, supports skin thickness and influences sebum, the natural oil that keeps skin moisturised. As testosterone levels gradually decline with age, typically from your mid-thirties onwards, the effects show up on your skin.

Skin becomes drier and thinner. Healing slows down. And hair follicles become more sensitive to dihydrotestosterone (DHT), a testosterone byproduct linked to male pattern hair loss.

The hormonal picture is complex, but nutrition can genuinely support healthy hormone balance. Zinc, vitamin D and omega-3 fatty acids all play a role.

The lifestyle villains quietly ageing your skin

You can eat all the right things and still undermine your skin if certain lifestyle habits are working against you. Some of the biggest culprits are so normalised that most men don’t even clock them as problems.

How does sun exposure accelerate skin ageing in men?

UV radiation is the single biggest external cause of premature skin ageing. It breaks down collagen and elastin, causes uneven pigmentation and increases the risk of skin cancer. Men are actually at higher risk than women here. Research suggests men are less likely to use SPF regularly and more likely to work outdoors.

The damage is cumulative. It builds up over the years without obvious signs, then seems to appear all at once. Daily SPF, even in the UK, even in winter, is one of the simplest things you can do to protect your skin long term.

Can stress and poor sleep really make you look older?

Absolutely. Chronic stress raises cortisol levels, which break down collagen, trigger inflammation and disrupt your skin’s ability to repair itself. It can also worsen conditions such as psoriasis, eczema and acne.

Sleep is when your skin does most of its repair work. Growth hormone, which supports cell regeneration, is released primarily during deep sleep. Cut that short regularly, and the effects show on your face. Research published in Clinical and Experimental Dermatology found that poor sleepers showed significantly more signs of skin ageing than good sleepers.

Then there’s alcohol and smoking. Both deplete key nutrients, impair circulation and accelerate collagen breakdown. They’re two of the most reliable ways to age your skin faster than nature intended.

What should men be eating for healthier skin?

The right foods don’t just support your general health. They actively feed your skin, hair and nails from the inside out. And the difference a good diet makes is genuinely visible.

Which foods actively support collagen production and skin repair?

Collagen synthesis depends on a steady supply of specific nutrients, particularly vitamin C. Your body cannot make collagen without it. Citrus fruits, kiwi, red peppers and broccoli are all excellent sources. Making them a daily habit is one of the easiest wins for your skin.

Protein is equally important. Collagen is a protein, and your body needs amino acids, especially glycine, proline and hydroxyproline, to build it. Good sources include:

• Bone broth: One of the richest natural sources of collagen-supporting amino acids
• Eggs: Contain proline and glycine, plus lutein for skin elasticity
• Oily fish: Salmon and mackerel deliver omega-3s alongside quality protein
• Legumes: A plant-based source of lysine, another key collagen-building amino acid

Antioxidant-rich foods matter too. Berries, green tea, dark chocolate and leafy greens all help neutralise the free radicals that break collagen down. Think of them as your skin’s defence team.

Are there specific nutrients you should prioritise for skin health?

Beyond vitamin C, a handful of nutrients deserve a special mention:

• Zinc supports collagen synthesis, regulates oil production and helps skin heal. Find it in pumpkin seeds, beef, lentils and shellfish
• Vitamin E protects skin cells from oxidative damage. Nuts, seeds and avocado are great sources
• Omega-3 fatty acids found in oily fish, walnuts and flax seeds reduce inflammation, support your skin’s lipid barrier and keep your skin hydrated
• Vitamin A supports cell turnover and skin repair. Sweet potato, carrots and leafy greens are all rich sources

The pattern here is simple. A varied, whole-food diet built around colour, quality protein and healthy fats gives your skin exactly what it needs to stay healthy as you age.

Can supplements really make a difference to men’s skin?

Always start with what’s on your plate. But the reality is that most men have nutritional gaps. Modern diets, busy lifestyles and the natural decline in nutrient absorption as you age mean supplements can play a genuinely useful supporting role.

Should you consider collagen supplements as you age?

Collagen supplements have come a long way from being dismissed as a women’s wellness trend. The evidence is growing. A 2019 review in the Journal of Drugs in Dermatology found that collagen supplementation improved skin elasticity, hydration and density. Another study in Skin Pharmacology and Physiology showed significant improvements in skin elasticity after just eight weeks of supplementation.

Hydrolysed collagen peptides are the most bioavailable form, meaning your body absorbs and uses them most efficiently. Look for products that also contain vitamin C, such as Nature’s Plus Unflavoured Collagen Peptides. Vitamin C is essential for collagen synthesis. Without it, even the best collagen supplement won’t reach its full potential.

Which other supplements are worth considering for men’s skin health?

A few others are worth having on your radar:

• Omega-3 fatty acids: if oily fish isn’t a regular fixture in your diet, a quality fish oil or algae-based omega-3 supplement is a smart addition
• Vitamin D: most people in the UK are deficient, particularly in winter. It supports skin cell growth, repair and immune function
• Zinc: particularly relevant if your diet is low in red meat or shellfish. Supports collagen production, skin healing and hormone balance
• Biotin: a B vitamin that supports keratin production, the structural protein found in hair and nails
• Astaxanthin: a powerful antioxidant derived from microalgae. Research suggests it can protect skin from UV damage and improve elasticity and moisture levels

As always, quality matters. Look for supplements that are third-party tested, free from unnecessary fillers and ideally sustainably sourced. Some of our most popular brands include Viridian, TERRANOVA, Together Health, DR.VEGAN and Kiki Health.

Hair and nails: The bigger picture

Skin gets most of the attention when it comes to ageing. But your hair and nails tell an equally important story, and they respond to nutrition in the same way.

Why do men’s hair and nails change with age?

Hair follicles are incredibly sensitive to nutritional status and hormonal shifts. As testosterone converts to DHT at increasing rates with age, follicles on your scalp can shrink, producing finer, shorter hairs over time. This is the mechanism behind male pattern hair loss, which affects around 50% of men by the age of 50.

But not all hair thinning is hormonal. Iron deficiency is a surprisingly common and often overlooked cause, even in men. So is low zinc, inadequate protein intake and deficiencies in vitamin D and B vitamins. If your hair has been thinning and you haven’t had your nutrient levels checked, that’s a good place to start.

Nails change with age too. They can become thicker, more brittle or prone to ridging and breaking. Brittle nails are frequently linked to low biotin, iron, zinc or protein intake.

Can nutrition genuinely improve hair thickness and nail strength?

Yes, with realistic expectations. Nutrition won’t reverse significant genetic hair loss, but it can absolutely support the health of existing follicles, slow thinning, and improve overall hair quality. Key nutrients include:

• Iron is essential for carrying oxygen to hair follicles. Low iron is one of the most common causes of hair shedding
• Zinc supports follicle repair and protein synthesis. A study in the Annals of Dermatology found zinc levels were significantly lower in men with hair loss
• Biotin supports keratin structure and is most effective where there’s an existing deficiency
• Silica, found in oats, bananas and leafy greens, it supports the strength and flexibility of both hair and nails
• Protein – hair is almost entirely made of keratin. Consistently low protein intake shows up as dull, weak and slow-growing hair

For nails specifically, a review in the Journal of Clinical and Aesthetic Dermatology found biotin supplementation improved nail thickness and reduced splitting in people with brittle nails. Your hair and nails are downstream of your diet. Feed them well, and they’ll show it.

What are the most important steps you can take today?

Skin, hair and nail health isn’t about expensive creams, elaborate routines or overhauling your entire lifestyle overnight. It’s about consistent, smart choices that add up over time.

Start with the basics. Eat a varied diet rich in colour, quality protein and healthy fats. Prioritise oily fish, eggs, leafy greens, nuts, seeds and plenty of vitamin C-rich foods. These are the building blocks your skin, hair and nails are literally made from.

From there, address the obvious lifestyle factors. Wear SPF daily, yes, even in Manchester in February! Prioritise sleep. Manage stress where you can. Cut back on alcohol if it’s a regular fixture.

Is it ever too late to start?

The simple answer is no. Your skin is a living, dynamic organ with a remarkable capacity to respond to better nutrition and care at any age. Studies show that dietary improvements and targeted supplementation can produce visible changes in skin quality within weeks to months, not years.

Your body is always rebuilding. Collagen turnover continues throughout your life. Hair follicles can be nourished and supported at any stage. Even brittle, damaged nails can recover with the right nutritional support.

The changes you make to your diet and supplement routine work from the inside out, which is exactly where lasting results come from.

Think of it less as a grooming routine and more as an investment. In your health, your confidence and how you show up in the world. Because when you feel good on the inside, it genuinely shows on the outside.
