Best Supplements For Skin

Skin health is influenced by far more than topical skincare alone. Hydration, elasticity, firmness, and overall skin appearance are closely linked to nutrition, collagen turnover, antioxidant status, and the skin’s ability to retain moisture. This is why interest in supplements for skin health continues to grow, particularly among people looking to support ageing skin, dryness, dullness, or loss of elasticity.

This guide focuses on the best supplements for skin available in the UK, selected from the Welzo catalogue based on ingredient quality, formulation relevance, and suitability for long-term use. Rather than chasing trends, the aim is to highlight supplements that support normal skin structure and function.

If you are also working on related areas like Skincare, Face Serums, or Beauty Supplements, choosing the right internal support can complement a consistent external routine.

What are skin supplements?

Skin supplements are nutritional products designed to support the skin from within by supplying vitamins, minerals, amino acids, fatty acids, or bioactive compounds involved in collagen synthesis, antioxidant defence, and skin hydration. Many people begin with collagen peptides and hydration support, then add targeted nutrients depending on their needs.

Because the skin is constantly renewing, nutrient availability matters. When intake is insufficient or demands are higher — such as during stress, ageing, illness, restrictive dieting, or environmental exposure — the skin may show signs such as dryness, reduced elasticity, slower repair, or dullness. Supplements can help support normal skin function where dietary intake alone may not be sufficient.

People building a skin-focused routine often explore related collections such as Collagen Supplements, Hyaluronic Acid, and Vitamin C Supplements, depending on whether the main goal is firmness, glow, or hydration.

What are skin supplements used for?

Skin supplements are used to support normal skin structure and function from within by providing nutrients involved in collagen formation, hydration, antioxidant defence, and skin barrier maintenance.

They are commonly used by people looking to improve skin elasticity, support hydration, reduce the appearance of dryness or dullness, and maintain healthy skin as part of an overall wellness routine. Many people exploring skin supplements also look at dedicated collagen supplements and hyaluronic acid supplements to support firmness and moisture retention from within.

Skin supplements may also be considered during periods when nutritional demands are higher, such as ageing, stress, restrictive dieting, or recovery after illness. In these cases, people often explore supportive nutrients like vitamin C supplements, which contribute to normal collagen formation, alongside broader beauty supplements designed to support skin appearance.

Most skin supplements are designed to support one or more of the following areas:

• Collagen support, to help maintain skin firmness and structural integrity, is commonly provided through collagen peptides

• Hydration support, to support moisture retention and skin plumpness, often using hyaluronic acid

• Antioxidant protection, to help protect skin cells from oxidative stress, using nutrients such as vitamin C

• Barrier maintenance, to support normal skin repair and resilience, which is often considered alongside a consistent skincare routine

It is important to note that skin supplements do not replace topical skincare, sun protection, or a balanced diet. Instead, they are used as an additional layer of internal support to help maintain normal skin health over time, particularly when paired with appropriate skincare products and healthy lifestyle habits.

Evidence is strongest when supplements are used consistently and paired with strong fundamentals: adequate protein intake, hydration, sleep, and daily sun protection.

External References & General Evidence on Skin Health

General information: how nutrition affects skin

Skin is a living, renewing organ that depends on a constant supply of nutrients to maintain structure, hydration, and barrier function. Proteins are required to build collagen and elastin, fats help maintain the skin barrier and prevent moisture loss, and vitamins and minerals support repair, antioxidant protection, and normal cell turnover. When nutrient intake is inadequate, or demands increase with age, stress, or illness, visible skin changes often occur.

Skin Structure & Ageing

“As we age, the amount of collagen and elastin in our skin decreases. This leads to loss of firmness, the formation of wrinkles, and changes in skin texture.”
— British Association of Dermatologists

This explains why supplements that support collagen formation are often discussed in the context of ageing skin.

“The dermis contains collagen and elastin fibres that provide strength, flexibility, and support to the skin.”

Collagen & Vitamin C (Why They’re Often Used Together)

“Vitamin C contributes to normal collagen formation for the normal function of skin.”
— European Food Safety Authority (EFSA)

This is the authorised health claim used across the UK and Europe, explaining why vitamin C is commonly paired with collagen supplements.

“Collagen supplements may improve skin elasticity and hydration in some people, but results are modest and vary between individuals.”
— Harvard Health Publishing

This helps users set realistic expectations and understand that supplements support normal function rather than create dramatic cosmetic changes.

Hydration & Hyaluronic Acid

General context:
Hyaluronic acid is a naturally occurring substance in the skin that helps retain water. With age, levels decline, which can contribute to dryness and reduced skin plumpness.

“Hyaluronic acid retains water and helps keep tissues well lubricated and moist.”
— National Institutes of Health (NIH)

This explains why hyaluronic acid is commonly used in hydration-focused skin routines.
https://www.ncbi.nlm.nih.gov/books/NBK557449/

“Hyaluronic acid plays a role in maintaining skin hydration and elasticity.”
— Cleveland Clinic

Vitamins, Minerals & Skin Maintenance

General context:
Micronutrients do not “beautify” skin directly, but they are essential for normal repair, immune defence, and antioxidant protection. When intake is low, skin may become dull, slow to heal, or more prone to irritation.

“Vitamins and minerals are essential for maintaining healthy skin and normal body function.”
— NHS

This supports the idea that supplements may be useful when dietary intake is inconsistent.
https://www.nhs.uk/conditions/vitamins-and-minerals/

“Eating a healthy, balanced diet helps ensure the body gets the nutrients it needs to function properly.”
— NHS

This reinforces that supplements work best as a complement to diet, not a replacement.
https://www.nhs.uk/live-well/eat-well/

“Diet plays an important role in skin health, influencing repair, resilience, and barrier function.”

Antioxidants & Environmental Stress

General context:
Environmental stressors such as UV exposure and pollution increase oxidative stress in the skin, which contributes to premature ageing. Antioxidants help protect skin cells from this damage.

“Antioxidants help protect skin cells from oxidative stress caused by environmental factors.”
— NIH (Scientific Review)

This explains why antioxidant nutrients are often included in skin-support routines.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5452224/

“Sun exposure is the most important environmental cause of skin ageing.”
— British Association of Dermatologists

Important context for readers: supplements cannot replace daily sun protection.
