Hydrates Good for Dry Skin
Dry skin is often characterized by redness, itchiness, tightness, flaking, peeling, and cracking. Dryness can be caused by a variety of factors: genetics, over-exfoliating, climate, diet, age, and skin conditions.
Explained
This ingredient is the magnesium salt of PCA (Pyrrolidone Carboxylic Acid). It is a great skin hydrator for the top layers of skin.
PCA is a natural humectant, meaning it draws water from the air to your outer layer of skin.
One study found magnesium ions improved skin hydration in the outer layer of skin, or the stratum corneum. However, it did not improve TEWL, or the transepidermal water loss. The TEWL is an indicator of how healthy your skin barrier function is. This study primarily looked at healthy skin with intact skin barrier.
Magnesium PCA is a rare cosmetic ingredient, with about 0.3% of the products in our database containing it.
