Le guide ultime pour stimuler le collagène après 40 ans

In your 40s, hormonal changes, especially during perimenopause, quietly affect your skin. As estrogen levels drop, your skin produces less collagen and elastin, making it feel drier, thinner, less firm, and more sensitive.

While these changes are natural, there’s plenty you can do to support your skin and boost collagen after 40 - from nutrition and movement to targeted skincare.

1. Nourish from Within

Estrogen helps maintain moisture, lipids, and collagen. When levels drop, it’s vital to support your skin from the inside.

1. Prioritize protein (to provide collagen’s building blocks)
2. Eat vitamin C-rich foods (to help collagen synthesis)
3. Add healthy fats like omega-3s (to keep skin supple)
4. Stay well hydrated

Bonus: A collagen peptide supplement paired with vitamin C can further support your skin’s own production. Try the Formetta supplement that nourishes from the inside-out and brings the ultimate skin replenishment.

2. Prioritise Rest and Stress Relief

Declining estrogen can disrupt sleep and raise cortisol, which speeds up collagen breakdown.

1. Keep a consistent sleep schedule
2. Limit screens before bed
3. Try meditation, stretching, or evening walks to lower stress hormones

A calmer nervous system gives your skin the best chance to repair itself overnight.

3. Keep Moving to Boost Circulation

Movement increases blood flow, which brings oxygen and nutrients to your skin cells.

1. Aim for 30 minutes of moderate activity (walking, Pilates, yoga, swimming) most days
2. Bonus: movement also helps reduce stress and balance hormones

4. Use Collagen-Targeted Skincare

Topical actives can help stimulate collagen production and strengthen the barrier:

1. Retinoids / peptides to trigger collagen renewal
2. Antioxidants like vitamin C to shield existing collagen
3. Hydrating ingredients like hyaluronic acid to plump

5. Shield Your Skin Every Day

UV rays are collagen’s biggest enemy - and protection is non-negotiable.

1. Apply broad-spectrum SPF 30+ daily
2. Avoid smoking and limit sugar (which damages collagen fibres through glycation)
3. Protect your skin from pollution with antioxidant-rich skincare

The Bottom Line

Hormonal changes are inevitable - but collagen loss doesn’t have to be.
By combining supportive lifestyle habits with targeted skincare, you can maintain firmness, bounce, and glow well into your 40s and beyond.
