Round Lab vs. SKIN1004: Which Is Better for Your Skin? A Complete Korean Skincare Comparison

If you are looking for the best Korean skincare products, you have probably come across Round Lab and SKIN1004, two popular Korean skincare brands, especially among people looking for gentle products focused on hydration, soothing, and sensitive-skin care.

But which one is better: Round Lab or SKIN1004?

Is Round Lab better for dry skin? Is SKIN1004 more suitable for sensitive skin? And which one should you choose if your main goal is hydration, skin barrier support, or achieving a healthy-looking glow?

The truth is that there is no single brand that works best for everyone. Each brand offers different product lines designed to address various skin concerns. Therefore, comparing products based on your specific skin concern is more important than comparing brand names alone.

In this guide, we will compare Round Lab and SKIN1004, explore the most popular product lines and products from each brand, and explain which options may be more suitable for dry, sensitive, oily, and combination skin.

Round Lab vs. SKIN1004: What Is the Difference?

Round Lab is known for its focus on ingredients inspired by Korea's natural environment. The brand offers several product lines featuring ingredients such as deep sea water, birch, mugwort, black soybean, and niacinamide. Some of its most popular lines include the 1025 Dokdo and Birch Tree lines.

Meanwhile, SKIN1004 is particularly well known for its Madagascar Centella line, which focuses on Centella Asiatica extract, along with other lines such as Hyalu-Cica, Tone Brightening, Poremizing, Tea-Trica, and Probio-Cica.

In simple terms:

Round Lab:
Focuses on hydration and everyday skincare with a variety of natural-inspired ingredients and specialized product lines.

SKIN1004:
Is particularly known for soothing, Centella-based skincare, hydration, and supporting the skin barrier, while also offering specialized lines for different skin concerns.

However, this does not mean that Round Lab is always better for hydration or that SKIN1004 is always better for sensitive skin. The specific formula and your skin's individual needs are the most important factors.

What Makes Round Lab Products Stand Out?

Round Lab offers several product lines, each with a different focus.

Some of the most notable include:

• 1025 Dokdo Line
• Birch Tree Line
• Mugwort Line
• Black Soybean Line
• Pine Cica Line
• Vita Niacinamide Line

The brand explains that its Birch Tree line is based on birch sap, while the Dokdo line uses deep sea water. Other lines target different aspects of skincare.

1. Round Lab Birch Moisturizing Serum

The Birch Moisturizing Serum is a popular option for anyone looking for lightweight and comfortable hydration.

Its formula contains hyaluronic acid, hydrolyzed hyaluronic acid, and birch sap. Round Lab describes it as a lightweight, watery serum formulated to help maintain the skin's moisture.

It may be suitable if you are looking for:

• Skin hydration.
• Improved appearance of dry skin.
• Smoother-looking skin.
• A lightweight serum that can be layered with other skincare products.
• A simple routine for sensitive skin.

Round Lab also classifies this serum as suitable for sensitive skin and all skin types.

2. Round Lab 1025 Dokdo Toner

The 1025 Dokdo Toner is one of Round Lab's best-known products. It belongs to the Dokdo line, which is based on deep sea water.

The toner can be applied after cleansing as a preparation step before serum and moisturizer.

If your main goal is to build a simple routine focused on hydration and everyday skincare, the Dokdo line may be worth considering.

3. Round Lab Birch Juice Moisturizing Line

If your skin tends to be dry, the Birch Tree line is one of Round Lab's product ranges most strongly associated with hydration.

According to the brand, birch sap is a key ingredient in this line, combined with a hyaluronic acid system designed to help hydrate the skin and maintain moisture.

Therefore, this line can be considered when your skin's main needs are hydration, comfort, and improved texture for dry skin.

What Does SKIN1004 Offer?

SKIN1004 offers a wide range of product lines, including:

• Madagascar Centella
• Hyalu-Cica
• Tone Brightening
• Poremizing
• Tea-Trica
• Probio-Cica
• Centella Teca
• Hyalu-Teca

This means that the brand is not built around a single product or ingredient. Instead, it has expanded its range to address different skin needs.

1. SKIN1004 Madagascar Centella Ampoule

The Madagascar Centella Ampoule is one of SKIN1004's most recognizable products.

It belongs to the line that focuses on Centella Asiatica and soothing skincare.

This makes it an appealing option for anyone looking for a simple routine focused on:

? Soothing the skin
? Hydration
?️ Supporting the skin barrier
✨ Maintaining a balanced-looking complexion

SKIN1004 positions its Centella line as gentle skincare for sensitive skin.

2. SKIN1004 Centella Soothing Cream

If you are looking for a lightweight moisturizer, the Centella Soothing Cream from SKIN1004 combines Centella with ingredients such as Trehalose, Sodium Hyaluronate, Ceramide NP, and cholesterol.

The brand describes the cream as a lightweight, non-sticky gel-cream designed to hydrate, soothe, and support the skin's natural barrier.

This highlights one of SKIN1004's strengths: some of its products combine hydration, soothing care, and skin barrier support in a single formula.

3. SKIN1004 Hyalu-Cica Water-Fit Sun Serum

Another popular SKIN1004 product is the Hyalu-Cica Water-Fit Sun Serum.

It is a serum-like sunscreen, and the brand states that it provides broad-spectrum SPF 50 protection with a lightweight texture and hydrating benefits.

Its formula includes ingredients such as:

• Centella Asiatica.
• Hyaluronic Acid.
• Panthenol.
• Rice Extract.
• Oat Extract.
• Soybean Extract.

According to the official product page, it is suitable for dry, normal, and combination skin.

Round Lab vs. SKIN1004 for Sensitive Skin

This is one of the most important points of comparison.

If you have sensitive skin, it is better to focus on the formula your skin needs rather than choosing a brand based solely on its popularity.

Round Lab

Round Lab offers products designed for hydration and sensitive-skin care. One example is the Birch Moisturizing Serum, which the brand describes as suitable for sensitive skin and all skin types.

SKIN1004

SKIN1004 clearly positions its Centella line around soothing care for sensitive skin. Some of its products also combine Centella with barrier-supporting ingredients such as ceramides.

Which One Is Better?

If your main focus is soothing, Centella, and supporting the skin barrier, you may prefer SKIN1004.

If you are looking for comfortable hydration and a simple everyday routine, Round Lab can also be an excellent option.

Round Lab vs. SKIN1004 for Dry Skin

Dry skin needs help maintaining water within the skin, so look for products containing hydrating ingredients such as:

• Hyaluronic acid.
• Glycerin.
• Panthenol.
• Ceramides.
• Ingredients that help reduce moisture loss.

Both brands can be suitable for dry skin.

Round Lab for Dry Skin

The Birch Tree Line stands out as an option for those focused on hydration, particularly because of the combination of birch sap and hyaluronic acid found in its products.

SKIN1004 for Dry Skin

The Hyalu-Cica line can be considered if you want to combine hydration with soothing care. Some SKIN1004 moisturizers also contain ingredients that support the skin barrier.

The winner?

There is no absolute winner, but:

? Hydration and a refreshing feel: Round Lab Birch
? Hydration + soothing + barrier support: SKIN1004 Hyalu-Cica/Centella

Round Lab vs. SKIN1004 for Oily Skin

Oily skin does not mean that it does not need hydration.

On the contrary, choosing a lightweight moisturizer can help maintain a balanced routine without relying on heavy formulas.

Round Lab

You can choose lightweight products, such as certain products from the Birch or Dokdo lines, depending on your skin's needs.

SKIN1004

SKIN1004 also offers lightweight products, including Centella and Hyalu-Cica formulas with watery or gel-like textures.

Therefore, if your skin is oily but also dehydrated, focus on the formula and texture rather than the brand name.

Round Lab vs. SKIN1004 for Hyperpigmentation

If your main concern is hyperpigmentation, the comparison becomes slightly different.

There is no single brand that can be considered the "hyperpigmentation brand," because results depend on the specific product and its ingredients.

SKIN1004 offers the Tone Brightening line, while Round Lab has also expanded into brightening products, including its Vita Niacinamide line.

However, when dealing with hyperpigmentation, do not rely on a serum alone.

Your routine should include:

Gentle cleansing → Brightening/hyperpigmentation treatment → Moisturizer → Sunscreen in the morning

Most importantly, stay consistent with sunscreen. UV exposure can worsen hyperpigmentation and make it more difficult to manage.

Round Lab vs. SKIN1004 for Acne-Prone Skin

If you have acne-prone skin, your product choice should depend on the type of acne and the specific concern you are trying to address.

SKIN1004 offers the Tea-Trica line, which is designed for blemish-prone skin, along with other lines such as Centella.

Round Lab also offers various products and lines, but its strongest reputation is more closely associated with hydration and everyday skincare.

Therefore, if your primary goal is a routine specifically designed for acne-prone skin, you may find more targeted options within SKIN1004.

If your goal is hydrating the skin while maintaining a gentle routine, Round Lab may be a good choice.

Which Is Better for Supporting the Skin Barrier?

If your skin feels tight or dry, or has become more sensitive due to excessive use of active ingredients, supporting the skin barrier may be one of your top priorities.

Round Lab

Some of its product lines include ingredients aimed at hydration and barrier care, such as the Black Soybean line, which the brand associates with ceramides, skin elasticity, and barrier care.

SKIN1004

The brand offers products that combine Centella with ceramides and other ingredients designed to support the skin barrier, such as the Centella Soothing Cream.

SKIN1004 may be more appealing if your primary goal is soothing the skin and supporting the barrier through a simple routine.
