I tried out the Medicated SP White Wrinkle Essence (quasi-drug, product number 2), which promises wrinkle improvement and whitening (*1) benefits when added to your regular skincare routine. *1: Suppresses melanin production and prevents dark spots and freckles. *2: [quasi-drug] Improves wrinkles. This serum contains niacinamide, which suppresses melanin production and prevents dark spots and freckles, simultaneously improving existing wrinkles and preventing future dark spots. The active ingredient, niacinamide, promotes collagen production, improving existing wrinkles. It also suppresses melanin production to address future dark spots. I apply it to my skin after washing my face. It has a slightly opaque, slightly thick texture, but it spreads easily and blends well with my skin. Its triple emulsion formula leaves it non-sticky and refreshing, while still providing a deeply hydrating finish.
The texture is refreshing and easily absorbed into the skin, moisturizing it deeply. It contains firming ingredients such as royal jelly fermented extract 4 and yuzu ceramide, which leave skin feeling plump and firm. The texture is smooth and spreads easily, so even a small amount spreads well. It has almost no scent, making it suitable for a wide range of people.
[Product Used] Perfect One Medicated SP White Wrinkle Essence [Product Features] Niacinamide promotes collagen production and improves wrinkles. It also targets dark spots. [Usage] Moderately creamy like a lotion. [Pros] Extremely effective. My skin feels revitalized and non-irritated while using this, and my nasolabial folds become less noticeable. [Not So Great] It applies well, so I finished it in under a month. [Who is this recommended for?] If you have various skin concerns, please give it a try. [How to Use] Use it as a lotion after applying lotion, then seal with a cream. #Tell Me Your Secret Glow #My One-Hand Makeup #Skincare I'll Definitely Buy Again #Summer Cosmetics Unboxing Video
