What Isntree Says
Product Description:
Isntree Chestnut AHA 8% Clear Essence removes dead skin cells mildly. Among various types of AHA, glycolic acid has the smallest molecular size, which makes it much faster when penetrating skin. Lactic acid has great moisturizing and exfoliating abilities. Together, they're the perfect pair. Glycolic acid (4%) and lactic acid (4%) work together to sweep away dead skin cells, revealing a smoother and brighter complexion. The formula also contains soothing centella asiatica and hydrating hyaluronic acid. Evens skin tone by exfoliating dead skin cells for smooth skin and improved uneven tone. Calms irritated and sensitive skin with Morus alba bark extract, centella asiatica extract, portulaca oleracea extract, and ginkgo extract. Free of parabens, pigment, artificial fragrance, animal ingredients, surfactants, mineral oil, alcohol, silicone and fragrance. Dermatologically tested with 0.00 skin irritation index and is low-irritant.
