Description
Mary & May Houttuynia Cordata + Tea Tree Serum 30ml is a minimalist Korean facial serum developed for oily, combination, sensitive-looking and troubled-looking skin. Its lightweight formula combines a high concentration of Houttuynia Cordata extract with tea tree extract to support soothing care, visible pore refinement and a fresher-looking complexion.
The serum contains 85% Houttuynia Cordata extract. Also known as heartleaf, Houttuynia Cordata is a botanical ingredient rich in naturally occurring flavonoids and polyphenolic compounds. In skincare, it is valued for antioxidant, soothing and moisture-supporting properties.
Houttuynia Cordata can help reduce the visible appearance of temporary redness and discomfort. It also contains naturally occurring polysaccharides that can complement hydration by helping the skin maintain surface moisture.
The formula contains 9.7% Melaleuca Alternifolia, or tea tree, extract. Tea tree extract supports the serum’s purifying and troubled-skin positioning while complementing care for excess surface oil and congestion-prone areas.
Tea tree extract should not be confused with undiluted tea tree essential oil. The ingredient list specifies a botanical extract rather than tea tree leaf oil. Even so, customers with tea tree sensitivity should patch test before full-face application.
The serum helps visible pores appear more refined by supporting hydration, surface-oil balance and cleaner-looking skin. It cannot permanently shrink pores because pore size is influenced by genetics, sebum production, age and skin structure.
This product is suitable for acne-prone skincare routines, but it should not be presented as a medical acne treatment. It can support calmer and clearer-looking skin, while persistent or severe acne may require professional dermatological care.
Glycereth-26 functions as a lightweight humectant and emollient. It helps attract moisture to the skin’s surface and contributes to a smooth application without creating an excessively oily finish.
Arginine is an amino acid and skin-conditioning ingredient. It also helps maintain the formula’s pH and complements the serum’s comfortable skin feel.
Caprylyl Glycol provides humectant and emollient support. It works alongside Glycereth-26 to help maintain hydration and softness in a formula designed primarily for oily and troubled-looking skin.
The formula contains only eight listed ingredients: Houttuynia Cordata Extract, Melaleuca Alternifolia Extract, Glycereth-26, 1,2-Hexanediol, Arginine, Carbomer, Ethylhexylglycerin and Caprylyl Glycol.
The minimalist ingredient list can be useful for customers who prefer straightforward formulations. However, a short ingredient list does not guarantee that every skin type will tolerate the product, so patch testing remains important.
Mary & May states that the formula contains EWG green-grade ingredients and has completed dermatological testing. The brand also states that it is free from animal testing and a specified group of potentially unwanted ingredients.
The serum contains no added artificial fragrance, artificial colour, mineral oil or drying alcohol according to the official product information. It should be described as fragrance-free rather than completely odourless because botanical extracts may have a natural scent.
The lightweight texture absorbs quickly and can be layered under other serums, moisturizers and sunscreen. It may be especially suitable during warm or humid weather when heavier soothing products feel uncomfortable.
Oily and combination skin may use the serum across the full face. Normal or dry skin can apply it to areas affected by temporary redness or visible congestion and follow with a suitable moisturizer.
Sensitive-looking skin should introduce the product gradually. Although Houttuynia Cordata is known for soothing care, tea tree-derived ingredients may not suit every reactive complexion.
Mary & May Houttuynia Cordata Tea Tree Serum can be used in both morning and evening routines. During daytime use, broad-spectrum sunscreen remains necessary because this serum does not provide ultraviolet protection.
