If there’s one thing I’ve learned as an asthetician, it’s that no skincare product—no matter how expensive or well-formulated—can do all the heavy lifting alone. Yes, topical skincare matters (a lot), but when it comes to healthy skin, the long-term results often start beneath the surface.
A skincare routine isn’t just about what you’re putting on your skin—it’s about what’s happening internally, too. Hormones, genetics, stress levels and even seasonal shifts all play their part. But one of the most overlooked factors? Nutrition. The skin is the body’s largest organ, and like any organ, it relies on a steady supply of nutrients to function at its best. When those levels dip, dryness, congestion and sensitivity are often the first signs.
When it comes to treating dry skin, I always talk about taking a 360-degree approach. That means pairing barrier-supporting serums and rich moisturisers with the right internal support. Think of supplements as your skin’s backstage crew—working behind the scenes to support hydration, strengthen the lipid barrier and improve resilience from within.
Of course, supplements aren’t a quick fix, nor are they a replacement for a solid skincare routine. But when used strategically, they can be transformative, especially for chronically dry or hormonally depleted skin. With the help of Suzanne Cooper, nutritionist and founder of GLOWWA, I've broken down the best supplements for dry skin and explained why they deserve a place in your routine alongside your favourite hydrators.
The Best Supplements for Dry Skin
- Best Overall Supplement: GLOWWA Collagen Creamer
- Best Omega Supplement: Advanced Nutrition Programme Skin Omegas
- Best Ceramide Supplement: The Nue Co Skin Hydrator
- Best for Mature Skin: Beauty Pie Youthbomb 360 Skin Elasticity Support
- Best Multitasking Supplement: Rejuvenated H30 Skin Repair
1. GLOWWA Collagen Creamer
This hardworking collagen powder is designed to upgrade your morning coffee while supporting skin firmness and hydration from within using a blend of hydrolysed collagen and added nutrients. It's one of my personal favourites because the formula is so thoughtfully formulated and emphasises ingredient quality. With daily use, the results are visible within just a few weeks.
"GLOWWA Collagen contains clinically backed peptan collagen peptides, which are hydrolysed for optimal absorption. Once absorbed, these peptides provide key amino acids that stimulate the body’s own collagen and hyaluronic acid production whilst supporting the skin matrix," explains Cooper. " Improved collagen structure helps enhance skin elasticity, whilst hyaluronic acid supports skin hydration, this leaves the skin looking smoother, more hydrated and delivers a natural glow."
Pros
- Quick results
- Easy to add to daily routine
- Pleasant taste compared to many collagen powders
Cons
- Not suitable for vegans
2. Advanced Nutrition Programme Skin Omegas
This omega blend combines EPA, DHA and vitamin A to support lipid levels in the skin and reinforce the skin's barrier function. It’s particularly helpful for very dry and sensitive skin that needs internal nourishment. I'm religious about taking these every day, but especially in winter, as I find they help my skin to feel less tight and more comfortable.
Pros
- Effective for dryness linked to barrier weakness
Cons
- Requires consistent long-term use
- Large capsule size
3. The Nue Co Skin Hydrator
Blending hyaluronic acid and collagen with the star ingredient, phyto-ceramide extract, this capsule targets hydration from multiple angles. It’s designed to support water retention and improve skin plumpness internally, complementing topical hydrating serums.
Pros
- Multi-ingredient hydration support
Cons
- Subtle, rather than dramatic results
- Expensive price point
4. Beauty Pie Youthbomb 360 Skin Elasticity Support
Price shown is member price.
This daily supplement from Beauty Pie focuses on supporting collagen and elastin production, making it ideal for mature skin that’s also experiencing laxity alongside dryness. The formula combines antioxidants and skin-structure-supporting nutrients to target elasticity from within.
Pros
- Targets structural ageing
Cons
- Expensive price point for non-members
5. Rejuvenated H30 Skin Repair
,Formulated with antioxidants and hydration-supporting nutrients, this supplement is designed to work while you sleep to support skin recovery and boost overall moisture levels. Keep it beside your bed and you'll never forget to take it.
Pros
- Supports damaged skin
Cons
- Results are visible over time, not quickly
6. Advanced Nutrition Programme Skin Moisture IQ
This advanced hydration formula requires you to take a selection of capsules, but this does mean that it targets ceramide production and moisture retention at a much deeper level. It’s particularly beneficial for those experiencing hormonally driven dryness. I found that my skin felt more supple and resilient with consistent use.
Pros
- Travel and on-the-go friendly
- Specifically designed for deep hydration
- Premium quality ingredients
Cons
- Requires taking multiple capsules, rather than one
- Expensive price point
7. Artah Essential Omegas
This high-quality omega supplement supports skin, brain and overall health in one streamlined formula. For dry skin sufferers in particular, essential fatty acids will help to restore lipid balance and improve skin softness over time.
Pros
- High quality formulation
Cons
- Results take time to see
8. Oskia MSM Bio-Plus
MSM (a bioavailable sulphur compound) plays a role in collagen production, making this supplement more about skin strength than immediate surface hydration—but that does improve hydration in the long term. It’s especially beneficial for improving texture and supporting ageing skin.
Pros
- Benefits skin, hair and joints
Cons
- Expensive price point
- May take time to benefit skin
9. Zooki Hyaluronic Acid
This liposomal liquid hyaluronic acid is formulated for enhanced absorption and easy daily use. Designed to complement topical hyaluronic acid (found in most hydrating serums), it aims to improve skin plumpness and moisture levels from within for an inside-out approach.
Pros
- Focused hydration support
Cons
- Improvements can be subtle
10. Epetome Symbiotic
Epetōme focuses on advanced cellular support and skin optimisation via a blend of vitamins, minerals, probiotics and prebiotics. So while it won't directly benefit hydration, it helps to support overall skin health, which means a stronger skin barrier and reduced dehydration over time.
Pros
- Broad skin-support benefits
Cons
- Expensive price point
- Often sold out
11. WelleCo The Skin Elixir
This powder supplement blends greens, antioxidants and skin-supporting vitamins to promote radiance from within. It’s less about single-ingredient hydration and more about comprehensive nutritional support for long-term skin health. You'll notice brighter, healthier-looking skin with consistent use.
Pros
- Pleasant taste
Cons
- Not hydration-targeted specifically
How does diet play a role in skin health and hydration?
While topical products hydrate and seal the surface, supplements work deeper. “Topical skincare works on the surface of the skin, but dryness often originates deeper within the skin’s structure and can be influenced by internal factors such as nutrition, inflammation and ageing,” says Cooper.
By delivering nutrients through the bloodstream, supplements reach the layers where collagen is produced, and new cells are formed. “Combining internal and external approaches creates a more comprehensive strategy,” she explains. “Topical products protect and moisturise the surface, while supplements help strengthen the skin’s foundation and long-term resilience.”
How does taking a supplement benefit dry skin?
When it comes to specific ingredients, certain nutrients consistently stand out. Cooper highlights “collagen peptides to support skin structure and elasticity” and “omega-3 fatty acids to strengthen the skin barrier and reduce moisture loss” as key players for dry skin.
She also recommends vitamins A, C, D and E for repair and antioxidant protection, alongside biotin and zinc to support overall skin health. Importantly, these nutrients don’t work in isolation. “These nutrients work synergistically to reinforce the skin barrier, improve water retention and support healthy cell turnover,” she explains, making combination formulas particularly effective for those with persistent dryness.
What kinds of supplements and ingredients benefit dry skin?
With the supplement market saturated, quality matters. “When choosing a supplement for dry skin, quality and bioavailability are key,” says Cooper. That means looking for clinically studied ingredients with evidence for skin benefits, alongside highly absorbable forms of nutrients. She also advises checking that dosages are aligned with research and avoiding unnecessary fillers or additives that don’t serve a purpose.
What should you look for in supplements for dry skin?
As much as I love a results-driven serum, skin health really starts from within. “Diet plays a fundamental role in skin health because the skin relies on a steady supply of nutrients to maintain its barrier function, elasticity, and hydration,” explains Cooper. In other words, if your nutrient intake is lacking, your skin is often the first place it shows up.
Cooper notes that “essential fatty acids, amino acids, vitamins and minerals help support collagen production, protect against oxidative stress, and regulate inflammation.” A diet rich in whole foods—healthy fats, colourful fruits and vegetables, and high-quality protein—helps maintain moisture balance from within whilst protecting against environmental stressors. Hydration isn’t just about water, either. “Hydration is also influenced by electrolytes and water intake, which support cellular function and help the skin appear plumper and smoother,” she adds.
How We Tested
I chose these supplements based on ingredient quality, bioavailability and their relevance to dry, barrier-compromised skin. I analysed each formulation for clinically supported nutrients such as essential fatty acids, ceramides, collagen peptides and hyaluronic acid, prioritising brands with transparent sourcing and strong customer feedback.
