What it is
This serum improves even the appearance of wrinkles. Achieve firm, radiant skin with a single product, all over your face. ● Formulated with wrinkle-fighting active ingredient Wrinkle Niacin, which works on both the dermis and epidermis. It adheres tightly to the skin, smoothing out wrinkles and improving troublesome lines while providing firm, uplifted firmness. It leaves skin smooth, moisturized, and radiant, with less visible wrinkles. ● This wrinkle-fighting cream serum is effective for all wrinkle concerns. ● Focusing on the "evening droop" that can be felt at the end of the day, it concentrates the bounty of the sea and earth, infusing moisture deep into the stratum corneum and delivering plump, uplifted firmness and radiance. The thread-like texture leaves skin feeling firm and radiant immediately after application, and with each use, it feels like you're no longer bothered by "evening droop." ●The stretch veil tightens the skin surface, enveloping it for a silky smooth feel. ●Despite its refreshing gel texture, it maintains moisture, softness, and silky smoothness. ●Contains a high concentration of astaxanthin*. The orange color of the contents is the natural color of astaxanthin. ●A gentle, clear fragrance that soothes both the skin and the mind.

How to use
Use this product in the morning and evening after preparing your skin with lotion. Take a pearl-sized amount on your fingertips and blend it into your face, starting from the center and working outwards. It can also be used on your neck. For areas where wrinkles are particularly noticeable, we recommend spreading the wrinkles with your fingertips and applying multiple layers, carefully blending the product into the wrinkle grooves. Finally, gently press your hands into your cheeks, enveloping them in your palms, to enhance firmness and radiance. For troublesome wrinkles around the neck, alternate between stroking down with the palms of your hands.

I feel the firming and moisturizing effect, and I also like the nice scent ♪
BAさんにおすすめされ購入最後に塗るだけで翌日乾燥知らずです
When I spread it on my skin, it felt moisturizing, but it absorbed quickly and didn't leave any sticky feeling. The next morning, my skin felt softer and firmer.
I like the scent of Predia, and it's soothing. The light gel feels great to apply. I was able to use it without any irritation, so I'm looking forward to the effects of astaxanthin and wrinkle niacin and will continue to use it.
Although it is labeled as a serum, I used it as a gel cream. It feels a bit sticky. Personally, I found the toner, emulsion, and serum series to be heavy except in the dead of winter, so I found it more comfortable to use two components: toner + emulsion or toner + serum. I wasn't sure about the effect on improving wrinkles.
