Collagen for Women Over 40: What It Does for Your Skin, Hair, and Nails

After 40, skin gets drier, fine lines get deeper, and hair can thin. Collagen for women over 40 helps with all three: studies show daily collagen can improve skin hydration, elasticity, and wrinkles in as little as 8 to 12 weeks. One scoop of Simply Halal Collagen Peptides gives you 14g of grass-fed collagen, more than most skin studies used.

What Changes in Your Skin After 40

Your body makes less collagen every year, and after 40 you start to see it in the mirror.

Collagen is the protein that keeps skin firm, plump, and smooth. As your body makes less of it, skin holds less water, lines deepen, and the firm feel of younger skin starts to fade.

Hair and nails can change too. Your hair grows from roots that sit deep in collagen-rich skin, which is why thinning hair and weaker nails often show up around the same time as fine lines.

Going through perimenopause or menopause? Falling estrogen speeds up collagen loss and affects your bones, joints, and sleep too. Read Collagen and Menopause for that side of the story.

What Collagen Does for Skin After 40

Skin is where collagen has the most research behind it, and the results are real.

A 2023 review in Nutrients looked at 26 studies with 1,721 people. Hydrolyzed collagen improved skin hydration and elasticity, the two things that make skin look plump and bounce back.

A 2024 study in Dermatology Research and Practice followed 130 adults aged 40 to 60, mostly women. After 12 weeks of daily collagen with vitamin C, skin hydration rose 13.8%, elasticity rose 22.7%, and wrinkles dropped about 20% compared with a placebo.

Women aged 38 to 50 saw even bigger changes in a 2024 study in Clinical, Cosmetic and Investigational Dermatology. After 56 days on a collagen beauty drink, wrinkle depth dropped 48% and skin hydration rose 15.7% compared with a placebo.

Collagen for Hair and Nails

Healthier skin and healthier hair go together, because your hair grows from your skin.

In the 2024 study of adults aged 40 to 60, expert graders rated hair as 31.9% healthier looking after 12 weeks of daily collagen, compared with 9.4% for the placebo group. In the study of women aged 38 to 50, hair fall dropped 28% in 56 days.

Collagen also gives your body glycine and proline, building blocks it uses for strong hair and nails. Want the deep dive? Read Halal Collagen for Hair, Skin, and Nails and Halal Collagen for Hair Loss.

The Vitamin C Boost

The skin studies with the biggest results paired collagen with vitamin C, and you can do the same.

Your body needs vitamin C to turn collagen’s building blocks into new collagen. Chef Maher believes nature gave us complete nutrition, not isolated molecules, so Simply Halal adds no lab-made ascorbic acid.

Instead, Strawberry Lemonade Collagen gets its 250mg of vitamin C (278% DV) from organic lemon and strawberry, with 13g of halal-certified collagen in every scoop. It’s collagen and vitamin C in one glass, the same pairing the studies used. Read more in Vitamin C and Collagen.

The Best Collagen for Women Over 40

The best collagen for women over 40 is hydrolyzed, Type I and III, filler-free, and truly halal-certified.

Hydrolyzed peptides. The collagen is broken into small pieces so it melts into your coffee and your body can soak it up. Every skin study above used hydrolyzed collagen.

Type I and III. Type I is the main collagen in your skin, and Type III works right alongside it. Grass-fed bovine collagen gives you both.

Zero fillers. Skip powders padded with maltodextrin. You’re paying for collagen, so that’s all that should be in the bag. Read Side Effects of Maltodextrin.

Real halal certification. Look for a named certifier, not just a “halal” word on the front. Learn what to check in Is Collagen Halal?, or compare brands with Best Halal Collagen Powder: The 5-Point Buyer’s Checklist.

How to Take Collagen After 40

Take it every day. In one study, daily collagen worked four times better than every other day.

1. Stir one 15g scoop of Simply Halal Collagen Peptides into your morning coffee, tea, or smoothie.
2. Add vitamin C. Have fruit with breakfast, or make your afternoon drink a scoop of Strawberry Lemonade Collagen.
3. Keep it daily. In the 2024 study, daily collagen cut collagen breakdown in the skin by 44.6%, versus 10.6% when taken every 48 hours.
4. Give it 8 to 12 weeks. Skin usually responds first, then hair and nails.
