Beusta Tranexamic Acid 7% Dark Solution Serum 30ml

A brightening serum powered by the synergy of arbutin and tranexamic acid

This is a brightening functional cosmetic that has completed its notification with the Ministry of Food and Drug Safety. Formulated with 4% arbutin and 3% tranexamic acid, it targets dull and uneven skin tone from multiple angles. The texture is hydrating yet lightweight, absorbing quickly without any sticky or heavy residue. Simply smooth it along the skin after toner.

Multi-action care with 4 brightening actives

Rather than relying on a single ingredient, this serum combines four dark spot-targeting actives to address hyperpigmentation and discoloration from every angle.

• Arbutin 4%: A naturally derived brightening ingredient extracted from bearberry and blueberry that helps block melanin production signals
• Tranexamic Acid 3%: A water-soluble amino acid that helps care for patchy dark spots and even out skin tone
• Niacinamide 2%: A Ministry-notified brightening functional ingredient that helps improve skin tone
• Glutathione 100ppm: Also known as Vitamin G, the same ingredient used in brightening injections, it helps enhance radiance

Panthenol and allantoin are also included to deliver hydration and soothing comfort to dry, rough skin.

For skin concerned with dark spots and dullness

Recommended for those whose skin looks dull due to melasma, freckles, or hyperpigmentation. If you have sensitive skin, patch test on the inside of your wrist first and start with a small amount, gradually increasing usage. It can be used in the morning, but since it does not contain SPF, sunscreen is essential when going outdoors. Because arbutin and ascorbic acid are sensitive to light and heat, make sure to close the cap tightly after use and store in a cool place.

Use after toner, during the essence or serum step

After cleansing and toning to prep your skin, apply while skin is still slightly damp for better absorption. Follow with your cream or moisturizer. For enhanced brightening results, pair with the Dark Solution Cream from the same line.

Safe for morning and evening use, but always follow with SPF

Tranexamic acid and arbutin are both suitable for daytime routines. However, since UV exposure is a leading cause of hyperpigmentation, always apply sunscreen before heading out if you've used this serum in the morning. In the evening, use it as an intensive brightening step to help address the day's accumulated stress on your skin.

Apply a moderate amount, following the skin's natural texture

Dispense 1–2 pumps into your palm and gently smooth over the entire face, following your skin's texture. The formula is hydrating yet lightweight, absorbing quickly without any sticky residue. For areas with visible dark spots or hyperpigmentation, feel free to apply a second layer for targeted care.

Recommended routine combinations by skin concern

• For a dull complexion: Start with a niacinamide-infused toner → this serum → moisturizing cream to focus on brightening
• For dark spots and post-blemish marks: Layer this serum with the Dark Solution Cream to maximize synergy
• If dryness is also a concern: Follow the serum with a cream containing panthenol or ceramides to reinforce your moisture barrier

Patch test first if you have sensitive skin, and store in a cool place

If this is your first time using the product or you have sensitive skin, test on the inside of your wrist before applying to your face, and start with a small amount. When used alongside high-strength retinol or vitamin C products, irritation may occur—adjust the amount or separate application times accordingly. Arbutin is sensitive to light and heat, so always close the cap tightly after use and store in a cool, dark place away from direct sunlight to prevent degradation.
