About the Product

A lightweight, calming serum built around Houttuynia Cordata—a plant extract used in traditional East Asian skincare known for its soothing properties. Combined with eight types of hyaluronic acid, it delivers hydration at multiple levels while helping calm redness and support your skin's moisture barrier. The texture is watery and absorbs quickly, with visible leaf bits from the Houttuynia Cordata.

Who is This For?

Suitable for all skin types, but especially helpful if your skin runs reactive, easily irritated, or dehydrated. A great option if you prefer plant-forward formulas and want hydration without heaviness.

FAQs

Q: Is ONE THING Houttuynia Serum safe for sensitive skin?
A: Yes, this product has completed skin irritation testing and is formulated for sensitive skin types, featuring calming Houttuynia Cordata extract.

Q: What are the visible leaf bits in the serum?
A: The visible particles are natural Houttuynia Cordata leaf bits included in the formula to deliver botanical benefits directly to the skin.

Q: Can I use this serum with other hydrating products?
A: Yes, the lightweight watery texture allows it to layer well with hydrating toners, essences, and moisturizers without pilling or heaviness.

Q: When should I apply this in my routine?
A: Apply after cleansing and toner, before heavier serums or moisturizer. The watery texture works best when applied to slightly damp skin.

A: It's best to use them at different times—skip strong AHAs, BHAs, or retinoids in the same routine to avoid potential irritation.

Q: How long before I see results?
A: Most users notice improved hydration immediately, while calming effects for redness and irritation typically become more visible within 1-2 weeks of consistent use.

Q: Does this serum need to be refrigerated?
A: Refrigeration isn't required, but storing it in a cool, dark place helps maintain the stability of the botanical ingredients.
