If you struggle with dry, dehydrated skin (especially in the Winter), Korean serums offer the best hydration without that crazy price point. We've tested loads of Korean Beauty serums available on Amazon, and these 10 deliver great moisture all for under $25. Here are my honest reviews and why each one made the list.

1. Beauty of Joseon Glow Serum - $16.95

With 60% Propolis & 2% Niacinamide, the Beauty of Joseon Glow Serum tackles uneven tone, dark spots, and dryness to reveal luminosity and your very own glow. Not only is it very hydrating, it also helps with the appearance of pores, it's great at balancing oil production and soothing and calming the skin.

Ingredients breakdown:

• Propolis Extract: also known as "Bee Glue" is collected by honey bees from bark and tree buds known for it's natural antibacterial, anti-fungal and and anti-inflammatory properties.

• Niacinamide: a form of vitamin B3 best used to treat acne, reduce redness, strengthen your skin barrier and improve overall skin texture.

Why we love it:

It's a serum that genuinely does what it says. Since using it, we've noticed immediate oil control and an actual 'glow' (which is hard to come by in these Winter months). It's also easy to layer, you don't need to wait ages for it to dry before putting on your moisturiser or any other serums. It's a great, daily product with proven results.

Best for:

• Oily skin

• Dull complexion

• Enlarged pores

What we would change:

Honestly there's not much that would deter us from buying this serum. The only thing we agreed was the dropper isn't the best, you need to go back into the bottle a couple of times to get enough serum. But that's all.

2. Anua PDRN Hyaluronic Acid Capsule 100 Serum - $23.28

This serum by Anua is all about hydration with PDRN, Collagen and 11 types of Hyaluronic Acid giving your skin that plump, glowing look. It's designed to give you a natural radiance and glass skin by maintaining moisture and smoothing texture.

Ingredients breakdown:

• PDRN: a more newer ingredient in Korean Beauty that helps repair skin and boost hydration at a cellular level, leaving skin looking healthier, boosted and more resilient.

• Collagen: helps maintain skin elasticity and firmness while supporting the moisture barrier.

• Hyaluronic Acid: the holy grail of hydration that holds up to 1000x its weight in water, plumping the skin and smoothing fine lines.

Why we love it:

It's a great first layer to the skin care routine. We like to use hyaluronic acid products on a wet face as that's how you can get the most out of it, so we've been putting it on straight after a shower. It soaks in quickly, it's not sticky and it genuinely leaves our skin looking plump and hydrated.

Best for:

• Dry to combination skin

• Dull complexion

What we would change:

This is a great serum for beginner PDRN users, but for those with a bit more experience using PDRN we would recommend a serum with a bit of a higher concentration.

3. COSRX Snail Mucin Repairing Serum - $17.99

With an amazing 96.3% Snail Secretion Filtrate, the COSRX Snail Mucin Essence is a favorite for good reason. This lightweight serum repairs damaged skin, retains moisture deep down, and rejuvenates dull, dehydrated skin while tackling fine lines.

Ingredients breakdown:

• Snail secretion filtrate: also known as "Snail Mucin" is full of ingredients like hyaluronic acid, glycolic acid and glycoproteins that stimulate collagen, repair skin damage and deliver great hydration.

Why we love it:

The texture is gel-like and absorbs quickly, making it perfect for layering under moisturizer and doesn't affect make-up application. We've noticed smoother, more plump skin after consistent use. Plus, knowing that no snails are harmed in the process (they collect the mucin in a safe, natural environment) makes us feel good about using it.

Best for:

• Damaged skin in need of repair

• Fine lines and signs of ageing

• Dry skin

• Dull complexion

What we would change:

The consistency can feel slightly slimy when you first pump it out, however it does absorb beautifully. If you're someone who's squeamish about the idea of snail mucin, it might take some mental convincing, but it's worth it!

4. SKIN1004 Madagascar Centella Ampoule - $16.40

Recently made popular by Heated Rivalry's Hudson Williams, SKIN1004's Centella serum is a gentle powerhouse for calming irritated or sensitive skin. The single-ingredient formula (yes, it's literally just Centella extract!) focuses on reinforcing your skin barrier, hydrating deeply, and giving you that healthy, balanced glow we all crave.

Ingredients breakdown:

• Centella Asiatica Extract: also known as "Tiger Grass" this ingredient is perfect strengthening your skin barrier, calming redness, and generating skin repair.

Why we love it:

This serum is simple, but one of the most effective we've tried. It's soothing, anti-inflammatory and promotes skin healing and it's visually noticeable after only a few uses. We've been using it in the AM and PM because we can't get enough of the glow it gives us.

Best for:

• Sensitive skin

• Redness or irritation

• Damaged skin

What we would change:

It's very lightweight and a more watery texture, so some people who prefer a thicker serum might feel like it's not rich enough. But we are convinced by this ingredient and this serum.

5. Medicube PDRN Pink Peptide Serum - $22

This beautiful pink serum is made with Salmon DNA PDRN, five types of peptides, niacinamide, and adenosine to target dull, uneven skin while boosting elasticity and hydration. The lightweight, milky texture absorbs quickly and layers beautifully with other products, making it an easy addition to any routine.

Ingredients breakdown:

• Salmon DNA PDRN: also known as "salmon sperm" is a bio-active ingredient that promotes skin regeneration, boosts collagen, and helps repair damaged skin for a clearer, more luminous complexion.

• Niacinamide: a form of vitamin B3 best used to treat acne, reduce redness, strengthen your skin barrier and improve overall skin texture.

• Adenosine: a water-soluble yeast-derived ingredient  that helps smooth wrinkles and boosts the production of collagen and elastin.

Why we love it:

This serum genuinely delivers on the "glass skin" promise. After a few weeks of use, we noticed our skin looking brighter, more even-toned, and noticeably plumper. It's gentle enough for daily use despite being packed with so many ingredients. It's become a daily staple.

Best for:

• Normal to dry kin

• Dull or uneven skin tone

• Early signs of aging

What we would change:

It's pretty, it's pink and it works but the price point is slightly higher than other serums. That being said, I think it's worth it.

6. Mixsoon Bean Essence - $23.98

This serum made viral on TikTok took the skin care world by storm, and honestly, we get why. The Mixsoon Bean Essence is a dual-purpose serum that exfoliates gently while staying deeply hydrating, making it perfect for anyone with textured or bumpy skin. With fermented bean, barley, pomegranate, and Korean pear, all of these ingredients work together to brighten your complexion, deliver antioxidants and smooth skin texture.

• Fermented Pomegranate: with natural AHAs, this ingredient exfoliates rough and flakey skin.

• Fermented Korean Pear: naturally hydrating and soothing, it helps calm irritation and provides an extra moisture boost.

Why we love it:

This essence is very versatile as a gentle exfoliator 2-3 times a week by massaging it into your skin until little bits of dead skin start to pill off, or you can apply it daily as a hydrating essence. We've noticed smoother skin texture and a more radiant glow and is our go-to for days when our skin feels sensitive.

Best for:

• Textured or rough skin

• Dull complexion

• Sensitive skin

What we would change:

As a hydrating serum, this is great. If you want this as an exfoliator only, it's not the most effective in exfoliation. But, if you've got sensitive skin that struggles with rougher exfoliators, this is the product for you.

👉 Find it on Amazon.

7. BIODANCE Hydro Cera-nol Serum - $21.90

BIODANCE have gone viral for their collagen sheet masks which have been well-used by us. And now they've put their formulas in serum form, what more could we ask for?

Why we love it:

This serum is a lifesaver if you're dealing with damaged or dehydrated skin. The texture is gel-like, but it absorbs quickly, leaving skin feeling soft and bouncy without any stickiness. We've noticed less redness and tightness since using it, and our skin genuinely looks more radiant.

Best for:

• Sensitive skin

• Dehydrated skin

• Redness or irritation

What we would change:

The bottle is quite small (1.01 fl oz), so if you're using it twice daily like we are, you'll go through it fairly quickly.

8. Pyunkang Yul Calming Moisture Serum - $15.99
