Product summary

Judging from the ingredient list, "Happy Face - 10% Azelaic Acid Skin-Clearing Gel-Cream" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Happy Face - 10% Azelaic Acid Skin-Clearing Gel-Cream ticks this box. Humectants in this product (glycerin and butylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (dimethicone, squalane and pentylene glycol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
