How is a cream-booster different from a regular hand cream?

A cream-booster like BISOU Gridem has a denser, more concentrated texture than a typical hand lotion. Regular lotions often contain more water and lighter emollients, so they absorb quickly but may need frequent reapplication. A booster formula prioritizes lipid-replenishing ingredients that rebuild the skin's protective barrier, smooth micro-cracks, and help the skin retain moisture longer between washings. Because it's concentrated, a pea-sized amount is usually enough for both hands. The trade-off is a slightly richer feel on application, which is why the instructions suggest massaging for about 30 seconds to help it absorb and warm cool fingers. If you prefer a very light, fast-absorbing lotion for daytime and something more protective for evening or harsh conditions, this format fits the latter role well.
