Both ectoin and niacinamide support the skin barrier - though they work differently to do so. Ectoin supports the skin barrier by binding moisture to the skin and creating a film on the skin that prevents water loss. Niacinamide helps to facilitate the production of ceramides and elastin, two critical parts of the skin barrier; it helps support the skin's natural shield.
Exfoliating is key to boosting your skin’s natural cell renewal, leaving you with a smoother, brighter complexion. By clearing away dead skin cells, it helps unclog pores, prevents dirt and oil buildup, and makes your other skincare products work even better.

While both glycerin and hyaluronic acid are excellent humectants with diverse applications, glycerin's smaller molecular size enables it to reach a bit further into the stratum corneum via aquaporins. This, combined with its molecular structure, allows glycerin to remain within the skin for a longer duration compared to water, which evaporates more readily.
