Macrocystis Pyrifera Extract

Whether the ingredient helps increase the skin’s water content — humectants that attract water, ingredients that reduce water loss, or ones that make skin feel less dry.

Whether it can calm the skin — linked to less redness, irritation, discomfort, or visible reactivity.

Whether it can improve smoothness and surface texture — roughness, flaking, clogged pores, or unevenness. Exfoliating acids, retinoids, and smoothing moisturizers may score here.
