When and how is it best to apply this body milk to get the most out of it?

The most useful window is right after bathing or showering, while the skin is still slightly damp. This is general body-care practice rather than something unique to this product: applying a moisturizing milk to damp skin helps trap water at the surface, and ingredients like panthenol, which attract and hold moisture, have more to work with. Pat the skin dry rather than rubbing it, then massage the milk in until absorbed.

Other situations where it fits naturally:

• After shaving — the source specifically mentions skin that feels rough after shaving; a light, non-greasy milk is generally more comfortable on freshly shaved legs than a heavy butter.
• On tight-feeling areas — shins, elbows, forearms and other spots that get dry between showers can be treated as needed during the day, since the texture absorbs without a sticky film.
• During seasonal changes — when heating or cold weather makes skin feel drier than usual, moving from occasional to daily application usually makes a noticeable difference in comfort.

Consistency matters more than quantity: a thin daily layer generally does more for skin softness than an occasional thick one. The product is for external use only, and you should avoid contact with the eyes.
