What is the role of caffeine and lime extract in this formula?

The active ingredients in this scrub are selected to complement the physical exfoliation with specific cosmetic benefits. Caffeine is commonly used in body cosmetics for its association with a firmer-looking appearance. When combined with the massage action required to apply the scrub, it is intended to help create a more toned visual effect on the skin. It does not permanently alter skin structure but may help reduce the appearance of fluid retention or looseness temporarily. Lime extract is included primarily for its refreshing properties. It adds a fresh, lively scent and is commonly formulated into products intended to refresh the look of tired or dull skin. The citric notes can provide a sensory awakening, making the shower experience feel more invigorating. Additionally, the formula contains Laminaria (brown seaweed extract), which is valued for its mineral-rich composition. This ingredient supports the goal of smoother, more supple-looking skin by providing minerals that may help maintain skin hydration and elasticity. These ingredients work synergistically with the shea butter, which coats the skin to prevent the dryness that can result from the salt and pumice exfoliation.
