Best Large Size Hydrating Serums for Face and Body in the UK

When it comes to skincare, hydration is non-negotiable. Whether you’re tackling dry facial skin, dehydrated body areas, or simply want that healthy, plump glow head-to-toe, a high-quality hydrating serum can transform your routine.

But here’s the problem many UK shoppers face: most serums come in tiny bottles that barely last a month.

If you’re serious about hydration, large size and bulk hydrating serums offer better value, better consistency, and better results.

In this guide, we rank the best large-sized hydrating serums for face and body in the UK, with a clear focus on performance, ingredients, value for money, and suitability for full-body use.

Why Choose a Large-Size Hydrating Serum?

Before we get into rankings, let’s address why bigger really is better when it comes to hydrating serums:

• Cost-effective – Lower cost per ml compared to standard 30ml bottles
• Face + body friendly – No need to ration your serum
• Ideal for dry skin – Perfect for UK weather and central heating
• Professional strength – Often, the same formulas are used in clinics
• Sustainable choice – Less packaging waste over time

If you apply serum daily (or twice daily), a bulk bottle simply makes sense.

1. Hollyberry Cosmetics Hyaluronic Acid Serum (Extra-Large Sizes) – Best Overall

Best for: Full-body hydration, dry & dehydrated skin, value for money
Sizes available: Large & bulk formats
Made in the UK

Why does it rank #1

Our Hyaluronic Acid Serum takes the top spot thanks to its exceptional hydration power, clean ingredient list, and availability in extra-large and bulk bottles designed for face and body use.

Formulated with high-purity Hyaluronic Acid, this serum attracts and retains moisture, helping skin feel instantly smoother, plumper, and more comfortable.

Unlike many facial serums, the lightweight texture absorbs quickly without stickiness—making it ideal for larger areas like arms, legs, chest, and neck.

Key benefits

• Deep, long-lasting hydration
• Suitable for face, body, hands & décolletage
• Lightweight, non-greasy texture
• Ideal for dry, sensitive, or dehydrated skin
• Outstanding price per ml compared to standard serums

Why it stands out:
Most brands sell hydration in tiny bottles. We designed ours for real-world use—daily, generous, and head-to-toe.

2. Budget-Friendly Large Hydrating Serums (High-Street Brands)

Best for: Entry-level hydration
Sizes: Medium-large bottles (usually up to 100ml)

Some UK high-street brands offer larger hydrating serums marketed mainly for the face. While they can work well for light hydration, they often fall short for full-body use due to thinner formulas or weaker concentrations.

Pros

• Easy to find

Cons

• Not designed for body application
• Lower active levels
• Less effective for very dry skin

Good option if you’re new to serums, but not ideal for long-term or full-body hydration.

What to Look for in a Large-Size Hydrating Serum

When choosing the best large hydrating serum for face and body, look for:

• Hyaluronic Acid (multiple molecular weights if possible)
• Lightweight, fast-absorbing texture
• No heavy fragrance (especially for body use)
• Suitable for daily use
• Good price per ml

Avoid products labelled “face only” if you want a true all-over hydrator.

How to Use a Hydrating Serum on Face & Body

To get the best results:

1. Apply to slightly damp skin after cleansing or showering
2. Use 1–2 pumps for the face, more for body areas
3. Seal with a moisturiser or body lotion
4. Use morning and night for maximum hydration

This method helps lock moisture into the skin more effectively.

Final Verdict: The Best Large-Size Hydrating Serum in the UK

If you’re searching for the best large size hydrating serum for face and body in the UK, Hollyberry Cosmetics Hyaluronic Acid Serum stands out for its:

• Extra-large & bulk bottle options
• Face + body versatility
• Professional-grade hydration
• Excellent value for money

Hydration shouldn’t be rationed. Your skin deserves more than a 30ml bottle.
