In South Korea, a functional cosmetic is a product category regulated separately from standard cosmetics by the Ministry of Food and Drug Safety (MFDS). To carry the functional cosmetic designation, a product must contain approved active ingredients at verified concentrations for one or more of the regulated functions: whitening (brightening), wrinkle improvement, UV protection, hair growth stimulation, or skin-firming for pregnancy-related concerns. The TG Dominas Cream RX carries designation for blemish relief (a brightening/whitening function) and wrinkle improvement, meaning the active ingredients and their concentrations have been reviewed and approved by the Korean regulator. This is a higher standard than an unregulated cosmetic claim.

Korean functional cosmetics can carry up to two or three certified functions in one product. The TG Dominas Cream RX combines blemish relief (addressing hyperpigmentation and uneven tone from post-acne marks or sun damage) with wrinkle improvement (addressing fine lines and skin firmness). The typical active combination for this dual function in Korean cosmetics uses a vitamin C derivative or niacinamide for the brightening function alongside a retinol-adjacent or peptide active for the wrinkle function. The full active list is on the Korean-language label included with each unit.

The TG Dominas Cream RX comes in a 10 g mini jar - a concentrated treatment format rather than a full-size moisturiser. At 10 g, this is sized for targeted spot application or for a complete facial treatment applied sparingly. The concentrate format keeps the active concentration higher per gram than a standard 50 ml cream, which is consistent with the RX (treatment-grade) positioning of the product. The 2-piece set provides 20 g total, covering roughly two months of once-daily spot treatment use or four to six weeks of full-face application at a thin layer.

Selling the TG Dominas Cream RX as a 2-piece set rather than a single unit follows Korean retail convention for concentrated treatment products where continuity of use over eight to twelve weeks is needed to see the functional results claimed on the label. The 2-piece set provides a supply sufficient for a full treatment cycle without a gap between the first and second jar. It also represents better value per gram than buying one jar and returning for a second at full price.

Apply a rice-grain amount to cleansed, toned skin as a treatment layer before a lighter moisturiser or as the sole final step in the evening. For spot treatment of post-acne blemish marks, apply directly to the mark rather than spreading across the full face. For full-face wrinkle improvement use, apply a thin, even layer from the centre outward. The cream should be used in the evening routine for dual-function products combining brightening and wrinkle actives, as some brightening actives (especially vitamin C derivatives) are less stable under UV exposure and wrinkle-improvement actives like retinoids increase photosensitivity.

Korean MFDS-certified functional cosmetics are evaluated for efficacy in clinical trials before certification. The approved results timeline typically runs four to twelve weeks of consistent daily use. Blemish relief from melanin-inhibiting actives shows gradual lightening of existing marks over six to eight weeks; new marks stop forming if the triggering cause (UV, acne) is also managed. Wrinkle improvement from retinoid or peptide actives shows texture improvement at the skin surface within two to four weeks, and deeper firmness change over eight to twelve weeks. Stopping use after the 10 g is used restores normal baseline over time, so continuity matters.

For any blemish-relief (brightening) functional cosmetic, sunscreen is essential in the morning routine. UV exposure re-triggers the melanin production that the brightening actives are working to suppress; applying the TG Dominas Cream RX at night and applying a broad-spectrum SPF 30+ sunscreen in the morning makes the two steps work in the same direction. Without morning sunscreen, UV damage can accelerate the formation of new blemish marks faster than the evening treatment can address existing ones, reducing the net visible result.
