Take the skin test and I'll show you how suitable this product is for you.
Take the skin testSoothe and protect sensitive skin with Hyeja's Vegan Niacinamide Heartleaf Calming Serum (95ml) a lightweight, herbal-infused elixir designed to soothe irritation and restore balance. Drawing from centuries-old Korean herbal wisdom, this serum features 60.76% heartleaf extract, revered for its calming and purifying properties. Infused with 2% niacinamide, it bolsters the skin's natural defences, refines texture and reduces redness, while ginseng and sugarcane extracts add a subtle vitality to your complexion. Its water-gel texture absorbs effortlessly, delivering soothing relief without heaviness.
Hyeja Vegan Niacinamide Heartleaf Calming Serum is a lightweight serum from Hyeja Skincare. The formula is built mainly around hydration and soothing. The ingredient list runs to 30 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. The oils in it point to a dewy, emollient finish rather than a matte one. Hydration is handled by Propanediol, Butylene Glycol and Glycerin, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Butylene Glycol, Glycerin and Ethylhexylglycerin.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Centella Asiatica Extract, Houttuynia Cordata Extract, Niacinamide and Tocopherol.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide, Ceramide NP and Hydrogenated Lecithin.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide and Tocopherol.
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.
The formula contributes little or nothing on cell renewal and firmness signalling. 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.
Reading the full list, the formula is fragrance-free, no drying alcohol, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain essential oils, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
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.
