This is a research-based guide. We did not personally use these products. Skincare results vary and cosmetic products do not treat medical conditions; patch test new products, and ask a dermatologist if you have a skin condition or concerns.

Quick Comparison Table

Tiers are relative within this group: Budget is the lowest cost here and Premium the highest. Check current cost on the product page, as it changes often.

1. medicube Exosome Shot Zero 2,000 PPM Spicule Serum: Best Texture-Focused Booster

• Name claim: Exosome Shot Zero 2,000 PPM
• Format: liquid booster serum with spicule
• Acids: AHA, BHA and PHA listed in the title
• Positioning: pores, sebum, texture and dead skin cells
• Size: 1.01 fl oz

Best for: oily or combination skin and anyone curious about the exosome booster trend. Skip if: your skin is sensitive, irritated or reactive, or you dislike tingling sensations.

Exosome serums are the newest wave in Korean skincare marketing, and medicube’s Exosome Shot is one of the most visible. The listing pairs an exosome ingredient with a spicule component, which are tiny structures meant to give a tingly, textured feel, and with a trio of acids (AHA, BHA and PHA) aimed at the surface of the skin. In plain terms, this is more of a texture and pore-focused booster than a gentle hydrating serum.

That combination is also why it deserves caution. Acids and spicule-type ingredients can cause stinging, redness or dryness, especially if you already use retinol or other exfoliants. Patch test on a small area, start with one or two evenings a week and skip it on irritated or broken skin. If you have a skin condition or are unsure, ask a dermatologist before adding it.

On the plus side, the lightweight liquid format layers well under moisturizer, and the 1.01 fl oz bottle is a manageable size for trying a trend without a big commitment. Follow with a moisturizer and daily sunscreen, since exfoliating ingredients make sun protection more important.

Pros

• Trend-forward exosome and acid formula
• Lightweight liquid texture
• Compact size for trial
• Targets texture and pore appearance

Cons

• May irritate sensitive skin
• Not for use with other strong exfoliants at the same time

2. REJURAN Dual Effect Ampoule with c-PDRN: Best PDRN Serum

• Key ingredient: c-PDRN from salmon DNA, per the listing
• Format: dual effect ampoule serum
• Positioning: firming, elasticity and barrier support
• Origin: Korean skincare
• Size: 1.01 fl oz

Best for: mature or dull-looking skin that likes a salmon DNA (PDRN) ampoule. Skip if: you want a budget serum or want to avoid animal-derived ingredients.

PDRN, short for polydeoxyribonucleotide, is a salmon-derived ingredient that skincare brands have embraced as a conditioning and skin-soothing component. REJURAN is one of the better-known names in the field, and this ampoule is positioned for rejuvenation, firming and elasticity, with the usual caveat that cosmetic products cannot change the structure of skin.

As a premium serum it is the most expensive pick here. If you are new to PDRN, you may prefer to try the ingredient in a lower-cost serum first. Because it is derived from salmon, people with fish allergies should check the ingredient list and speak to a doctor before using it.

Use it after cleansing and toning, before moisturizer, and follow with sunscreen in the morning. Introduce one new active at a time so that you can tell how your skin responds.

Pros

• Recognizable PDRN brand
• Focus on firmness and barrier support
• Dual effect format
• Pairs with simple routines

Cons

• Costs the most in this guide
• Contains an animal-derived ingredient

3. BIODANCE Collagen Peptides Jelly Serum Mist: Best Hydrating Jelly Mist

• Format: sprayable hydrogel jelly serum mist
• Key ingredient: collagen peptides, per the title
• Use: hydrating face spray
• Size: 1.69 fl oz, travel-friendly
• Positioning: Korean skincare gift and travel essential

Best for: hydration on the go and touch-ups over makeup or during travel. Skip if: you want a concentrated treatment serum.

BIODANCE is best known for its collagen hydrogel masks, and this jelly serum mist brings the same jelly texture in a spray bottle. It sits between a facial mist and a serum: the jelly consistency clings to the skin for longer than water-based mists, which helps with a dewy look and with the sensation of hydration.

Think of it as a hydration step rather than an active treatment. It suits midday refreshes over makeup, a quick layer before moisturizer and travel kits, thanks to the 1.69 fl oz size. Because it is a mist, use it with clean hands and close your eyes when spraying.

Collagen peptides in skincare act mainly as hydrating, conditioning ingredients on the surface; they do not replace collagen in the skin. If you have sensitive skin, patch test first and check the ingredient list for fragrance.

Pros

• Easy to apply anywhere
• Jelly texture clings to the skin
• Compact size for travel
• Layers over makeup

Cons

• Light on actives
• Mist application can waste product

BIODANCE Collagen Peptides Jelly Serum Mist (1.69 fl.oz) | Hydrating Face Mist, Anti-Aging Face Spray, Sprayable Hydrogel Mist, Travel Essentials & Self Care Gifts, Korean Skin Care

Included for 'Best Korean Skincare Serums: Exosome, PDRN, Collagen and Jelly' because the listing adds cooling or gel-infused layers, which is the attribute this article compares.

4. medicube Jelly Gel Mask with Firming NAD EGF: Best Overnight Jelly Mask

• Format: overnight jelly gel mask
• Key ingredients: NAD and EGF, per the title
• Count: 4 single-use packets of 28g
• Positioning: firming, Korean skincare
• Use: overnight

Best for: a weekly overnight treat as a jelly-style mask step. Skip if: you want a daily serum or dislike sleeping in masks.

Jelly mask skincare has been growing as people look for a middle step between a serum and a sleeping cream. medicube’s version arrives in four 28g packets with NAD and EGF listed, intended as an overnight gel mask for firmer-looking skin. It is technically a mask rather than a serum, but it fits the serum-adjacent shelf and the keyword searches around jelly masks.

Single-use packets are convenient because there is no jar to contaminate and you can use one a week as a treat. Apply after your serum, leave it on as directed and rinse or leave on according to the instructions on the packaging.

Because it contains active-sounding ingredients, patch test first and avoid it on irritated skin. If you have concerns about specific ingredients, check with a dermatologist.

Pros

• Single-use packets stay fresh
• Jelly texture feels cooling
• Easy weekly routine
• Pairs with any serum

Cons

• Not for daily use
• Packets add packaging waste

5. Anua Niacinamide 10 + TXA 4 Serum: Best Niacinamide Serum for Dull-Looking Skin

• Key ingredients: niacinamide 10 and TXA 4, with hyaluronic acid
• Positioning: dark spot care and glass skin
• Texture: lightweight, hydrating all-in-one daily serum
• Size: 1.01 fl oz
• Origin: Korean skincare

Best for: uneven-looking skin tone and a simple one-bottle routine. Skip if: you are sensitive to niacinamide or want an exfoliating serum.

Anua has become a household name in Korean skincare, and this serum combines 10 percent niacinamide with 4 percent tranexamic acid and hyaluronic acid. Niacinamide is among the best-researched cosmetic ingredients for the look of tone and pores, while tranexamic acid is a popular partner in tone-evening products.

The listing describes a lightweight, hydrating daily serum, so it suits most routines from morning to night. Use it after cleansing and toning, then moisturizer and sunscreen. Daily sunscreen is essential if you are using any product for the look of dark spots.

As always, results vary and cosmetic products cannot treat medical conditions. If you have persistent hyperpigmentation, see a dermatologist.

Pros

• Well-known, widely used formula
• Lightweight and hydrating
• Easy to layer
• Suits daily use

Cons

• May cause irritation in sensitive users
• Results are gradual and vary

6. Beauty of Joseon Glow Deep Serum with Rice and Alpha-Arbutin: Best for Radiance and Gentle Brightening

• Key ingredients: rice extract, alpha-arbutin and niacinamide
• Positioning: dullness, radiance, hydration and uneven tone
• Size: 30 ml (1.01 fl oz)
• Brand: Beauty of Joseon
• Origin: Korean skincare

Best for: dull skin and a gentle brightening routine. Skip if: you want a strongly acidic exfoliating serum.

Beauty of Joseon blends traditional Korean ingredients with modern formulas, and the Glow Deep Serum pairs rice extract with alpha-arbutin and niacinamide. Rice has a long history in Korean beauty, and alpha-arbutin is a common brightening ingredient in cosmetics.

This is a gentle approach to radiance: it does not rely on strong acids, so it is a friendlier option for people who want a glow without the tingle. Use it morning or night, under moisturizer, and expect gradual changes over weeks, not days.

Sunscreen is essential with any brightening product. If you have sensitive skin or known allergies, patch test first.

Pros

• Gentle formula without strong acids
• Rice extract and alpha-arbutin
• Pairs well with other routines
• Popular and widely discussed

Cons

• Gradual changes only
• Not a substitute for sunscreen

7. COSRX Snail Mucin 96% Power Repairing Serum: Best Classic Hydrating Serum

• Key ingredient: 96 percent snail secretion filtrate, per the title
• Positioning: hydrating and soothing, dull skin and fine lines
• Size: 3.38 oz, the largest in this guide
• Texture: gel-like, stretchy
• Origin: Korean skincare

Best for: a bouncy, hydrating serum that works for most skin types. Skip if: you avoid animal-derived ingredients or are allergic to snail products.

COSRX’s snail mucin serum is among the best-known Korean serums worldwide, and the large 3.38 oz bottle gives the best volume for the cost. The texture is a stretchy gel that some people love for its bouncy hydrated feel and others find slightly sticky.

It is a gentle option for most skin types because the formula focuses on hydration and conditioning rather than strong actives. Apply two or three drops after toning, pat in, and follow with moisturizer.

Snail-derived products are not vegan, and people with shellfish or mollusk allergies should ask a doctor first. Patch test on a small area as with any new serum.

Pros

• Large bottle at a low cost
• Simple, hydrating routine step
• Popular and widely available
• Gentle for many skin types

Cons

• Sticky texture for some
• Not vegan

How We Chose

We began with the product listings for the main picks and compared ingredients named in the titles, formats and sizes. To cover the trends behind the secondary search terms, we included an exosome booster, a PDRN ampoule, a collagen jelly mist and an overnight jelly mask, alongside three proven classics for niacinamide, rice and snail hydration.

Our research relies on maker listing details and general skincare guidance from dermatology organizations. We did not personally use these products and do not claim measured results. Where an ingredient percentage or full ingredient list was not in the title, we do not state it.

We kept at most two products per brand and avoided quoting exact costs because they change often.

Buying Guide

Start with your goal

Serums work by delivering a concentrated set of ingredients. For hydration, look for hyaluronic acid, snail filtrate or centella. For tone and texture, niacinamide and alpha-arbutin are common. For surface exfoliation, AHA, BHA and PHA acids are used. Choose one goal at a time so you can tell what is working.

If your skin is dry, choose a hydrating serum first; if it is oily, a niacinamide or acid-based serum may be more useful.

Understand the trending ingredients

PDRN is a salmon-derived ingredient used in conditioning products. Exosome ingredients are marketed as skin boosters; the science for topical cosmetic use is still developing, so treat claims cautiously. Collagen peptides in skincare act on the surface as humectants and conditioners and do not replace collagen in the skin. NAD and EGF appear in newer firming products.

A product can be pleasant and effective for hydration without delivering dramatic anti-aging changes.

Patch test and introduce slowly

Introduce one new serum at a time and patch test behind the ear or on the inner forearm for 24 hours. Start with a few nights a week for acid or spicule products and increase if your skin tolerates it. Stop and seek advice if you see persistent redness, swelling or pain.

If you have eczema, rosacea, acne or any skin condition, ask a dermatologist before adding active serums.

Layer correctly

Apply serums from thinnest to thickest after cleansing and toning: a mist or hydrating serum first, then treatment serums, then moisturizer, and sunscreen in the morning. Jelly masks go on after serums when you use them. Avoid combining multiple strong actives in the same routine.

Wait about a minute between layers so that each product can absorb.

Check size, format and storage

Size affects value: a 3.38 oz bottle lasts much longer than a 1.01 oz bottle, but a smaller bottle is wiser for trying a new trend. Pump or dropper packaging protects ingredients better than open jars. Store serums away from heat and sunlight, and note the period-after-opening symbol on the label.

Single-use packets suit travel and trials.

Common Serum Mistakes

• Using several strong actives at once.
• Skipping sunscreen while using exfoliating or brightening products.
• Expecting cosmetic serums to work in days.
• Not patch testing a new formula.
• Ignoring the period-after-opening symbol and using products long past their date.

Frequently Asked Questions

What are the best Korean skincare serums?

The best serum depends on your goal. Anua Niacinamide 10 + TXA 4 is a popular all-rounder, COSRX Snail Mucin is a classic for hydration, and Beauty of Joseon Glow Deep is a gentle choice for radiance.

Does collagen face serum really work?

Collagen in a topical serum is too large to replace the collagen in your skin, but collagen peptides can hydrate and condition the surface, which helps skin look smoother and plumper.

What is an exosome serum?

Exosome serums are a newer cosmetic trend that use exosome-derived or exosome-inspired ingredients, often paired with other actives. Evidence for topical cosmetic use is still developing, so keep expectations modest and patch test.

What is jelly mask skincare?

Jelly masks are gel-textured masks, often used overnight or as a weekly treat. They add hydration and a cooling texture, and are applied after serums.

Can I use PDRN serum every day?

Many people use PDRN products daily, but follow the instructions on the label. Check the ingredient list for allergens, and note that PDRN is derived from salmon.

Should I use serum morning or night?

Hydrating and brightening serums can be used both morning and night. Exfoliating or spicule serums are usually used at night, and sunscreen should always follow in the morning.

Are Korean serums safe for sensitive skin?

Many are gentle, but sensitivity depends on ingredients. Patch test, avoid fragrance if you react to it, and ask a dermatologist for skin conditions.

Which One Should You Buy?

Start with Anua if you want one dependable serum, or COSRX if hydration is your priority. Choose the medicube Exosome Shot if you want to try the texture trend and your skin tolerates acids, REJURAN for PDRN, BIODANCE for a jelly mist, and the medicube Jelly Gel Mask as a weekly overnight treat. Beauty of Joseon is the gentle pick for a glow.

Whatever you choose, introduce one product at a time, patch test, and always finish the morning routine with sunscreen.
