Overview: What Is the CANMAKE Mermaid Skin Gel UV?

CANMAKE is a Japanese drugstore cosmetics brand from IDA Laboratories, and its Mermaid Skin Gel UV has become one of its best-known products. It is a water-based gel meant to replace several skincare steps at once: CANMAKE’s official Japanese site describes it as an all-in-one product that covers skincare, a moisturizing base, and UV protection after cleansing, listed at ¥770 (tax included) for 40 g as of 2026-08-04. It comes in several tinted variants, including a clear version described as suitable for any skin tone.

Key Ingredients and How It Works

UV Filters

According to CANMAKE’s official Japanese product page, the formula is rated SPF50+ and PA++++, combining chemical UV filters, including ethylhexyl methoxycinnamate, with mineral filters such as zinc oxide and titanium dioxide, according to the ingredient list on INCI Decoder. This mixed chemical-mineral approach is common in Japanese sunscreens, though we did not independently test the product’s actual sun-protection performance.

Hydrating and Skin-Conditioning Ingredients

CANMAKE markets the gel as containing moisturizing and skin-conditioning ingredients including sodium hyaluronate, glucosyl ceramide, and centella asiatica extract. The fuller third-party ingredient list also includes dimethicone and several plant extracts. We did not independently confirm the complete list against a single complete primary source.

How to Use It

CANMAKE’s official directions say to apply it after cleansing, using it in place of lotion, serum, moisturizer, and a makeup base in a single step, and to reapply every two to three hours for continued sun protection. A third-party retailer listing also describes use on the body.

Pros and Cons

Pros

• Combines hydration, makeup base, and UV protection in one product, according to the brand
• SPF50+ and PA++++ rating on the Japan-market packaging
• Multiple shade options, including a clear version
• Lightweight water-gel texture

Cons and Considerations

• The official US listing does not display an SPF/PA rating on its packaging
• Choosing the wrong tinted shade can leave a visible mismatch
• The complete ingredient list has not been independently confirmed against a single primary source

Who Is This For?

Likely a Good Fit

Readers who want to simplify their morning routine with a single hydrating, tinted, sun-protective step may find this appealing, particularly if they like lightweight water-gel textures.

Consider Checking First

The product’s alcohol-free and fragrance-free status is stated by third-party retailers but was not directly confirmed on CANMAKE’s Japanese site during this research. Readers with known sensitivities should review the full ingredient list and patch test before regular use. Those whose priority is a specific verified SPF rating should confirm they are buying the Japan-labeled version.

Japan Formula vs. the US Listing: What’s the Difference?

CANMAKE’s official Japanese site lists the product with an SPF50+ and PA++++ rating, while its official US site lists the product without an SPF or PA claim on the packaging, noting a change made for US regulatory compliance. We have not independently confirmed whether the underlying formula differs or only the labeling changed.

Where to Buy and Price

CANMAKE’s official Japanese site listed the product at ¥770 (tax included) for 40 g as of 2026-08-04. CANMAKE’s official US site listed it at $12.00 for 1.41 oz (40 g) as of the same date, without an SPF/PA claim on the packaging. Prices and regional labeling can vary, so check the current listing before purchasing.

Our Verdict

The CANMAKE Mermaid Skin Gel UV is a budget-friendly example of the Japanese all-in-one sunscreen-gel category, and the Japan-market version carries a clearly labeled SPF50+/PA++++ rating on the brand’s site. Review evidence was limited, so we would treat it as a reasonable option for readers drawn to the format, with the important caveat that the US-listed version does not carry the same labeled SPF/PA claim.

Frequently Asked Questions

Is the CANMAKE Mermaid Skin Gel UV good for sensitive skin?

Third-party retailers describe the formula as alcohol-free and fragrance-free, but we could not confirm those claims directly on CANMAKE’s Japanese site. Check the full ingredient list and patch test, especially if you have a known skin condition.

Does the US version have the same SPF protection as the Japan version?

Not as far as the labeling shows. The Japanese site states SPF50+ and PA++++, while the US site does not display an SPF or PA rating. We have not confirmed whether this is only a labeling difference or a formulation difference.

How do I pick the right shade?

CANMAKE offers several tinted variants, including a clear option. Starting with the clear version may be a practical choice if you are unsure about shade matching.

Can I use it as a moisturizer?

CANMAKE markets it as an all-in-one step that can replace lotion, serum, moisturizer, and makeup base after cleansing. Whether that is enough depends on your skin and routine.

Where can I buy it, and how much does it cost?

It is available through CANMAKE’s official Japanese and US sites as well as international retailers. Confirm the regional version, current price, and labeling before buying.
