買うべきはどっち？【新うるおい密封vs美白*】イハダお勧め解説！プチプラなのが不思議すぎる隠れデパコス級化粧水＆乳液はコレ！

Product Overview

The video compares IHADA’s renewed Moisturizing line with its Medicated Clear (“Plus Whitening”) line. The reviewer presents both as affordable drugstore skincare with thoughtfully designed formulas for sensitive or trouble-prone skin. No numerical rating or score is given.

Renewed Moisturizing Line

Products

• Medicated Moisturizing Lotion, available in moist and very moist versions
• Medicated Moisturizing Emulsion

Formula and Renewal

The products contain allantoin and dipotassium glycyrrhizinate, which are intended to soothe irritation and help prevent rough skin and acne. The reviewer notes that acne prevention comes from reducing inflammation, rather than from antibacterial action.

The formula also includes high-purity petrolatum to help protect the moisture barrier. The products are described as mildly acidic, free of artificial colorants, alcohol, and parabens, allergy-tested, and formulated to be less likely to cause acne or rashes. The emulsion also contains a ceramide-related ingredient.

The renewed formula and texture are lighter and less sticky than the previous version. The reviewer notes that the lotion’s glycerin content appears lower. The bottle now has a convenient one-touch cap instead of a screw cap. The updated formula spreads and absorbs more naturally, addressing the previous version’s heavier, surface-level feel.

Use Experience and Prices

Both lotion textures felt relatively light. Even the very moist version was not especially dense, though it left a noticeable moisturizing film.

• Lotion, 180 ml: ¥1,650
• Lotion refill, 150 ml: ¥1,320
• Emulsion, 135 ml: ¥1,760
• Emulsion refill, 110 ml: ¥1,430

Medicated Clear / Plus Whitening Line

Products and Formula

The line consists of Medicated Clear Lotion and Medicated Clear Emulsion. It has not been renewed.

Its active ingredients are tranexamic acid—called m-tranexamic acid in the video—and dipotassium glycyrrhizinate. In addition to soothing and acne-prevention benefits, tranexamic acid helps suppress melanin production to prevent spots and freckles.

The reviewer describes the ingredient pairing as unusual for an affordable product and compares its formulation approach to department-store cosmetics. He also highlights ingredients that support moisture and penetration.

Use Experience and Prices

The lotion and emulsion feel lighter and fresher than the Moisturizing line, without noticeable scent or stickiness. The emulsion still provides good moisture, and the reviewer reports no stinging.

The lotion bottle has a relatively wide opening, so dispensing requires care. Both products retain screw caps.

The reviewer notes that people sensitive to DPG may find the Moisturizing line easier to use.

• Lotion, 180 ml: ¥1,980
• Emulsion, 135 ml: ¥2,090
• Refills: Not currently available

Main Comparison and Verdict

• Choose the Plus Whitening line for everyday basic care, especially if preventing spots and freckles is a priority. The reviewer prefers it if choosing only one line, because of its added brightening benefit. Although it costs more and has older packaging, he considers it good value and describes it as having “hidden department-store-cosmetics quality.”
• Choose the Moisturizing line when skin is irritated, dry, or more reactive, such as during seasonal or hormonal changes. The reviewer considers its soothing effect stronger, particularly because of allantoin. Its renewal also makes it a better option for people who disliked the previous version’s stickiness.

The reviewer’s suggested approach is to use the Whitening line as the regular routine and add or switch to the Moisturizing line when skin is in poor condition.

Speaker Perspective

The video features one reviewer, Kanosuke, who evaluates the formulas and shares his firsthand impressions of their textures. He favors the Whitening line for routine use and recommends the renewed Moisturizing line as a more soothing option during periods of irritation.
