The quest for youthful, radiant skin is timeless. With growing scientific research, several supplements have been found to improve skin elasticity, hydration, firmness, and reduce wrinkles. Here are the top 5 supplements backed by meta-analyses and robust randomised controlled trials (RCTs).
1. Collagen Peptides
- Effect on Skin: Improves skin elasticity, reduces wrinkles, and enhances hydration.
-
Scientific Backing: Collagen peptides are widely studied for their effects on skin health. A 2021 meta analysis of 19 studies involving over 1,100 participants found that collagen supplementation significantly improved skin elasticity, hydration, and reduced wrinkles .
-
How it Works: Collagen is a structural protein that provides skin with its firmness and elasticity. As we age, natural collagen production declines, leading to sagging skin and wrinkles. Supplementation with collagen peptides helps to replenish collagen levels and stimulate further production.
-
Dosage: 2.5-10 grams per day for 8-12 weeks has shown significant improvements in skin appearance.

2. Hyaluronic Acid
-
Effect on Skin: Enhances skin hydration and smoothness, reducing fine lines and wrinkles.
-
Scientific Backing: A systematic review of RCTs from 2021 concluded that oral hyaluronic acid significantly improves skin moisture content and reduces wrinkle depth. Studies have demonstrated that supplementation enhances skin hydration and elasticity .
-
How it Works: Hyaluronic acid is a natural component of the skin that retains moisture. It can hold up to 1,000 times its weight in water, making it a critical factor in maintaining skin hydration and plumpness. Oral supplementation has been shown to improve moisture levels from within.
-
Dosage: 120-240 mg per day for 4-12 weeks is typically recommended for noticeable improvements in skin
hydration and firmness.- Buy Hyaluronic Acid HERE
3. Coenzyme Q10 (CoQ10)
- Effect on Skin: Reduces fine lines and wrinkles, improves skin firmness, and enhances antioxidant defences.
-
Scientific Backing: Several RCTs have shown that CoQ10 supplementation helps to reduce wrinkles and improve skin smoothness. A 2020 meta-analysis confirmed that CoQ10 improves skin elasticity and reduces oxidative stress, which contributes to skin ageing .
-
How it Works: CoQ10 is a powerful antioxidant that neutralises free radicals, which can damage skin cells and accelerate ageing. It also supports cellular energy production, which is essential for skin repair and renewal.
-
Dosage: 100-300 mg per day has been shown to reduce signs of ageing after 12 weeks of use.

4. Omega-3 Fatty Acids (EPA/DHA)
-
Effect on Skin: Enhances skin hydration, reduces inflammation, and improves skin barrier function.
-
Scientific Backing: Omega-3 fatty acids, particularly EPA and DHA, have been shown in RCTs to improve skin hydration, reduce roughness, and enhance skin barrier function. A 2018 meta-analysis found that omega-3 supplementation can improve skin elasticity and decrease the appearance of wrinkles .
-
How it Works: Omega-3 fatty acids reduce inflammation, which can accelerate skin ageing and damage. They also support the skin’s lipid barrier, which retains moisture and protects against environmental stressors.
-
Dosage: 1,000-2,000 mg of combined EPA/DHA per day for 12 weeks has demonstrated positive effects on skin hydration and elasticity.

5. Vitamin C
- Effect on Skin: Boosts collagen production, reduces pigmentation, and improves skin firmness.
-
Scientific Backing: Vitamin C is a potent antioxidant essential for collagen synthesis. RCTs have demonstrated that oral vitamin C can improve skin elasticity and reduce wrinkle depth. A 2017 study found that vitamin C supplementation improves skin hydration and reduces roughness .
- How it Works: Vitamin C plays a critical role in collagen production and acts as an antioxidant, protecting the skin from free radical damage caused by UV exposure and pollution. This leads to smoother, firmer skin and a reduction in fine lines.
-
Dosage: 500-1,000 mg per day of vitamin C for 12-16 weeks has been shown to significantly improve skin quality.
