How should I apply it and how often can I use it?

The routine is simple:

1. Start with clean, dry hands. Good moments are after finishing housework, after coming in from outdoors, or in the evening when the skin feels hard and depleted.
2. Apply a small amount of the liquid and massage it into the rough areas — fingers, knuckles, palms. The texture is thin and spreads quickly, so you do not need much.
3. Let it absorb. It does not require rinsing and does not leave a thick film, so you can carry on with your day shortly afterwards.

As for frequency, there is no fixed schedule — use it when the skin actually feels coarse. Someone doing daily manual work or frequent hand washing might use it once or twice a day during a rough period, then drop back to occasional use once the texture improves. Because the formula contains ethanol and ammonia, it is not meant as a constant all-day product the way a bland moisturizer might be; treat it as a targeted step rather than something you reapply every hour.

A few practical points: apply only to intact skin — avoid open cracks, cuts or freshly irritated areas, where it can sting. Use it in a ventilated room, keep it away from the eye area, and store the bottle away from heat and open flames. Following up with your usual hand cream once the liquid has absorbed works well, especially overnight.
