Tea-Trica Relief Ampoule

Each SKIN1004 product line centers on one active; in the Tea-Trica range, this ampoule is that centerpiece. The Purifying Toner handles daily maintenance. The B5 Cream hydrates and buffers. The Relaxing Mask provides weekly intensive care. This ampoule performs the actual treatment work—the layer that targets active breakouts, reduces sebum output, and fades marks. This framing matters for evaluation. You aren’t asking “is this nice?”—you are asking “does it do the job?” For the right skin type, it does.

The INCI shows tea tree leaf water at the top, not water. SKIN1004 uses this pattern across the Tea-Trica line, much like their cica line uses a high-centella-water base. The product vehicle carries antimicrobial activity against Cutibacterium acnes before other actives even act. Published clinical research shows tea tree works on mild-to-moderate inflammatory acne. While most research uses higher-concentration essential oil gels, the water and leaf extract forms carry the same antimicrobial compounds without the sting. Using them as the base provides the benefit without the irritation.

Betaine salicylate is the second major active, which distinguishes this ampoule from the toner. A toner typically doses betaine salicylate for daily maintenance. This ampoule uses it as a treatment-grade step; the INCI placement suggests a concentration in the full 4% Korean formulation range. This is approximately equivalent to 0.5% traditional salicylic acid but has less surface sting due to slower release. It performs real pore-turnover work. Paired with the tea tree water base, the antimicrobial and keratolytic mechanisms hit different targets in one session.

Niacinamide sits higher on the INCI in this ampoule than in the rest of the line. It is likely in the 4-5% range, the sweet spot for sebum regulation via sebocytes, post-inflammatory hyperpigmentation support, and barrier maintenance. Research on niacinamide at these concentrations is extensive and well-replicated. Zinc PCA adds sebum-balance support and beta-glucan adds immunomodulatory soothing, making the supporting cast unusually complete for an acne serum. Beta-glucan is an under-recognized addition; its anti-inflammatory and wound-healing profile pairs naturally with the centella triterpene layer.

That centella layer prevents this ampoule from being a “works but hurts” acne product. All four triterpenes appear in the INCI. They dampen the inflammation BHA and tea tree might trigger and support barrier function during dehydrating treatment phases. SKIN1004 uses this same pattern across the Tea-Trica line, allowing this ampoule to work twice daily instead of every other day. Without the centella, it would require a more cautious application schedule.

Texture

The texture is a lightweight gel that absorbs in about thirty seconds without stickiness. Three to four drops cover the face; more will pill under follow-up moisturizer or sunscreen. There is no sting or adjustment period on application—the formulation is engineered for immediate comfort. Breakout reduction usually shows by the end of the first week, and post-inflammatory marks start fading by the third or fourth week.

Honest limitations

Honest limitations: this is not for dry, sensitive, or rosacea-prone skin. The tea tree and BHA combination is too much for reactive types. It is not pregnancy-safe due to the betaine salicylate, and it is not strictly fungal acne safe because of the PEG ingredient—though tea tree actives sometimes fit fungal acne routines depending on tolerance. For severe cystic acne, use this as an adjunct to prescription treatment, not a replacement. The glass dropper is slower than a pump, a minor ergonomic issue rather than a formulation one.

At around $28 for 50ml, the value is fair. It costs similarly to the Probio-Cica Intensive Ampoule from the same brand and is meaningfully cheaper than Western acne serums with comparable ingredient density. For oily or combination skin with mild-to-moderate inflammatory acne seeking a daily treatment serum that won’t sting, this is a strong K-beauty option—and it is the Tea-Trica product the rest of the line organizes around.
