Review: 早速使ってみました。翌朝の肌のもっちり感が使用前と使用後では全然違います！ ベタつきすぎずでも保湿力があり、リピート確定です！
Review: 乾燥、シミに悩んでいて、tiktokなどの情報を元に購入しました。使用して日にちは浅いですが、肌が落ち着き言葉では言えない手応えは感じています。 匂いはなくべたつかず、良い潤いです。 しばらく続けるつもりです。

乾燥、シミに悩んでいて、tiktokなどの情報を元に購入しました。使用して日にちは浅いですが、肌が落ち着き言葉では言えない手応えは感じています。 匂いはなくべたつかず、良い潤いです。 しばらく続けるつもりです。

### ⭐⭐⭐⭐ Review
*by N***N on March 3, 2026*

肌への効果はまだわかりませんが、荒れたりはしません。 スッと入り込むので、次に使うお手入れとの相性が良いと思います。 ひとまず一本使い切ってみようと思います。
