Mixsoon Heartleaf Essence [100ml]

Water, butylene glycol, houttuynia cordata extract. That is the entire formula — no preservative system beyond the glycol, no fragrance, no emulsifier, no thickener, nothing to give reactive skin a second thing to react to. Heartleaf, Houttuynia cordata, is the plant Korean formulators have long used for flushed, irritated and blemish-prone skin, and the compound Mixsoon points to in it is quercitrin, a flavonoid glycoside. The brand processes the extract over roughly 72 hours at low temperature specifically to preserve that kind of heat-sensitive constituent. The 100 ml is the full retail size: the bottle for someone who has already decided this works and is using it twice daily, in layers, as a soaking essence on cotton pads, or generously across face and neck — the use patterns that run through a small bottle in a fortnight.

Key Benefits

• Three ingredients in total, which is close to the shortest INCI on any leave-on essence in the category — the single most useful property for genuinely sensitive, reactive or newly compromised skin.
• Houttuynia cordata (heartleaf) extract is the sole active, valued in Korean skincare for calming visible redness, settling irritation and supporting blemish-prone complexions.
• Quercitrin, the flavonoid Mixsoon highlights in heartleaf, is an antioxidant compound; the brand's low-temperature 72-hour extraction is designed around retaining it.
• Free of fragrance, essential oils, alcohol, parabens, silicones and colourant, and marketed as vegan and fungal-acne-considered — it clears most of the screening filters buyers apply to sensitive-skin ranges at once.
• Watery, non-tacky slip that absorbs in seconds and layers under serums, ampoules, creams and sunscreen without pilling — genuinely useful in humid Gulf conditions where heavy hydrating layers are unwelcome.
• Helps take the edge off oily-feeling, congested skin without any stripping agent in the bottle.
• Butylene glycol does double duty as the extraction solvent and a light humectant, which is why the formula can hydrate on three ingredients.
• The 100 ml size is the value and repeat-purchase format — better cost per millilitre for the customer and the natural hero SKU of the Heartleaf line in a K-beauty wholesale assortment.

When to Use

Morning and evening, as the first hydrating step after cleansing — either in place of a toner or immediately after one, and always before serums, emulsions and creams. It is the product for skin that is angry rather than damaged: post-shave redness, flushed cheeks after sun or heat, the tender area around a healing spot, the tightness that follows a retinoid or acid night. Because it holds no acids, retinoids or vitamin C, it is also the essence to reach for on rest days from an active routine, and it can be layered alongside niacinamide, panthenol and hyaluronic acid serums without conflict. Suitable for all skin types including sensitive and blemish-prone, and gentle enough that the brand positions it for teenage as well as adult skin. The generous size makes it practical for face-and-neck application and for the seven-skin layering method, where a small bottle runs out too fast.

How to Use

Dispense four to five drops into clean palms or onto a cotton pad. Press into damp skin rather than rubbing, working outward from the centre of the face, and pat until the surface no longer feels wet — about twenty seconds. With 100 ml in hand, use it the way the size invites: layer two or three thin applications in succession on dehydrated skin instead of one heavy pour; carry it down onto the neck and chest; and for a targeted calm on a red or reactive area, soak two cotton pads and leave them on as a compress for five to ten minutes. It also doubles as a DIY sheet-mask liquid on a dry compressed mask, and can be decanted into a fine-mist bottle for a refresher through the day. Follow with serum, moisturiser and, in the morning, sunscreen. Suitable for twice-daily use.

Key Ingredients

• Houttuynia Cordata Extract (heartleaf) — the only active in the bottle. A Korean botanical staple for soothing visible redness, calming irritated and blemish-prone skin and helping skin that feels overheated. Mixsoon extracts it over roughly 72 hours at low temperature to protect flavonoids such as quercitrin. No standardised percentage of active compounds is published by the brand, and none is claimed here.
• Butylene Glycol — the extraction solvent and carrier, and a lightweight humectant in its own right; it is what gives the essence its fast-absorbing, residue-free finish.
• Water — the base of the formula. There is nothing else in the bottle.

Precautions

No sun-sensitivity warning applies — this formula contains no AHA, BHA, retinol or vitamin C. The main thing to flag is the flip side of a three-ingredient formula: with only butylene glycol standing in for a conventional preservative system, hygiene matters. Close the cap firmly, do not touch the dropper or bottle neck to the skin, store it away from direct sunlight, heat and bathroom steam, and finish an opened 100 ml bottle within a reasonable period rather than leaving it half-used for a year. Houttuynia cordata is a single plant extract, so a small number of people will simply be sensitive to it — patch test on the inner forearm or behind the ear before the first full-face use. Avoid the immediate eye area and do not apply to open, broken or sunburned skin. Discontinue use if redness, itching, swelling or any other unusual irritation appears, and consult a dermatologist if it persists. Keep out of reach of children.
