Ingredients
How to use
1. After washing your face, dispense a coin-sized amount (0.6 mL) into the palm of your hand. 2. Place an appropriate amount on your forehead, cheeks, and chin, and use your fingers to massage the skin in circular movements, lifting it up, until it blends into your entire face. 3. Take another small amount onto your fingertips and apply it to areas prone to dryness, such as around the eyes, mouth, and chin, blending gently. *If you feel your skin is not moisturizing enough, use this product after applying your regular lotion. *For those who are concerned about sunburn, we recommend using your regular sunscreen after using Skin Tune Up Serum.

Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
