Why Collagen Declines With Age (and What Your Body Is Telling You)
Collagen doesn’t disappear overnight but once it starts to decline, your skin feels it. Why? Because it’s the most abundant protein in the body and helps to provide structure, strength and elasticity to connective tissue - including your skin, joints and tendons. It also provides vital amino acids (such as keratin) which form the building blocks for hair and nail health. Collagen essentially acts as a glue supporting the body’s integrity and scaffolding structures - which not only affects its appearance but also its strength and resilience.
From your mid-20s onwards, your body begins to slow down its natural collagen production with reductions of approximately 1% per year. It’s a gradual shift: collagen synthesis slows, existing collagen breaks down faster and skin structure becomes less resilient over time.
The decline is considered part of the normal ageing process and is the result of us both naturally producing less collagen plus our body breaking down existing collagen at a faster rate.
By the time many women reach their 30s and 40s, the effects of collagen loss start to become more visible.
Women may start to notice subtle changes in their early 30s. This may look like early fine lines and reduced skin bounce. As they head into their 40s, these changes may be more noticeable with skin thinning and dryness becoming part of the picture as they enter perimenopause.
This timeline can vary: collagen decline can also be further exacerbated by diet and environmental factors such as smoking, diets high in sugar, UV radiation from sun exposure, chronic stress and lack of hydration.
Signs of collagen loss you shouldn’t ignore
The signs of collagen loss are often subtle at first, then gradually more visible. These may include:
Fine lines and wrinkles becoming more pronounced
Skin feeling less firm or “elastic”
Dryness or loss of glow
Slower recovery after breakouts or irritation
Thinning hair or brittle nails
Joint stiffness or reduced flexibility
These changes may all be connected to declining structural support beneath the skin.
Ageing skin and collagen: what’s really happening
When we talk about ageing skin and collagen, we’re really talking about support loss beneath the surface.
Collagen acts like a dense, supportive mesh. As that mesh weakens, skin becomes thinner, elasticity decreases and volume loss becomes more visible.
Collagen and menopause: why the shift feels faster
The link between collagen and menopause is significant.
Oestrogen plays a key role in maintaining collagen levels. As oestrogen declines during perimenopause and menopause collagen production drops more rapidly, skin dryness increases and loss of firmness accelerates.
How to support collagen naturally
While collagen decline is a natural part of ageing, there are ways to support your body from within. Focus on these foundations:
1. Nutrient-rich diet
Vitamin C, zinc, copper, and protein are essential building blocks for collagen formation. Include nuts, seeds and colourful fruits and vegetables in your diet.
2. Sun protection
UV exposure is one of the fastest ways to break down collagen in the skin. Using a daily SPF is essential.
3. Lifestyle balance
Sleep, stress management, and avoiding smoking all support healthier collagen turnover.
4. Movement and circulation
Exercise helps deliver nutrients to skin and connective tissues more efficiently.
5. Targeted supplementation
Many women choose collagen supplements as part of their routine to help support skin elasticity and hydration from within.
While collagen decline is a gradual, natural process tied to ageing, hormonal shifts, and lifestyle, there is so much we can do to support our body. From nutrition to daily lifestyle tweaks, small changes can make a meaningful difference in how you age - and how you feel in your skin.
Because ageing isn’t about stopping time. It’s about supporting your body through every stage of it.
