About Citrus Unshiu + Tremella Fuciformis Serum
Overview
Citrus Unshiu + Tremella Fuciformis Serum is a lightweight serum from Mary&May, a brand based in Korea. The ingredient list runs to 9 ingredients, each broken down in full below.
Texture and finish
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order.
What the formula does
Hydration: Moderate. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Ethylhexylglycerin, Glycereth-26 and Arginine.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Arbutin.
Who it suits
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
What it does not target
The formula contributes little or nothing on barrier support, antioxidant protection, oil control and soothing. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
What is not in it
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
Where it fits in a routine
It can be used morning and evening. In a routine it goes before moisturiser. Tap along the orbital bone with your ring finger; product migrates upward on its own.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
