General, ingredient-based — not your personalized match.
See how this fits your skin
Take the skin test and I'll show you how suitable this product is for you.
Take the skin testThe iUNIK Tea Tree Relief Serum is a calming serum formulated for dehydrated and sensitive skin. Made with 67% of tea tree leaf water known for its anti-inflammatory and antimicrobial benefits and ability to cure troubled skin, and 19.7% of the centella asiatica extract to soothe redness or irritated skin. niacinamide, and adenosine are present to boost the brightening and antiwrinkle effects.
Tea Tree Relief Serum is a watery-light serum from IUNIK. The formula is built mainly around hydration and soothing. The ingredient list runs to 33 ingredients, each broken down in full below.
By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte. Hydration is handled by Butylene Glycol, Sodium Hyaluronate 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 Butylene Glycol, Sodium Hyaluronate, Glycerin and Betaine.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Centella Asiatica Leaf Water, Centella Asiatica Extract, Allantoin and Beta-glucan.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Dipotassium Glycyrrhizate and Glycyrrhiza Glabra Root Extract.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide.
On richness alone it suits Combination (oily) and Oily 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 antioxidant protection, 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, 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.
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.
