    The MECCA view

    A 3-in-1 serum of clean, kind-to-skin ingredients that gently smooths with lactic acid in Hadasei-3™, plumps with hyaluronic acid, and locks in moisture with squalane for smoother, plumper, dewier skin.

    Key ingredients

    Lactic Acid in Hadasei-3™: Our proprietary complex of Japanese superfoods Uji green tea, Akita rice and Okinawa algae comprises 73% of The Dewy Serum. The three superfoods are given new life through a double fermentation process that generates high levels of naturally-occurring lactic acid and gentle AHAs that smooth the look of lines and improving texture.

    Hyaluronic Acid: A polysaccharide that naturally occurs in the skin. This moisture-binding molecule helps skin retain moisture for a hydrated, plump appearance.

    Sugarcane-derived squalane: A saturated and stable hydrocarbon naturally found in the skin, which works as a humectant to seal in moisture and keep skin hydrated throughout the day.

    Made without

    Mineral oil, synthetic fragrances, sulfate detergents, parabens, urea, DEA, TEA, or phthalates.


    Ideally apply Tatcha's Essence first on clean skin to amplify the results of The Dewy Serum. Massage 1-2 pumps onto clean, dry skin morning and night.
