What it is
As if to say "Thank you for a day's hard work." Gently envelop your hard-working hands with silky gentleness for five minutes, gently relaxing them. Enjoy special nighttime care for your hands with the dual use of serum and hand treatment cream. Introducing the limited-edition Thanks size from the Retreat Hand series. We created this special nighttime care series for your hands, offering intensive care and rest, just like skincare while you sleep. The dual use of serum and hand treatment cream creates a silky, moisturizing veil for hands you'll want to touch again and again. The serum thoroughly moisturizes before the cream, plumping up the skin's texture. Massage promotes blood circulation and reduces the appearance of fine lines and dullness caused by dryness. The pleasant, gentle scent of lily of the valley, lavender, and geranium ensures a restful night's sleep.

On days when my hands are really dry, I apply this serum, then top it off with unscented hand cream before going to bed! I was so impressed that my hands were moisturized again the next morning.
It's a thick serum that absorbs quickly and easily onto the skin. It leaves my skin feeling moisturized and soft without any stickiness. I can even use my smartphone right after use without feeling sticky, so I highly recommend it. The subtle herbal scent is also soothing.
This is better than hand cream! My husband is sensitive to smells and can't use hand cream very often, but this is no problem! Plus, it's not sticky, which is great!
After applying this serum, I applied hand cream and put on gloves before going to bed, and my hands were smooth the next day. I would like to use it again.
Just apply it to dry hands and it will replenish moisture. The hand cream you apply afterwards will also be absorbed nicely.
