## Description

Arbutin and tranexamic acid bring two highlighted ingredients together in one spicule-infused serum, making it easy to add a radiance-focused step to a regular skincare routine. The formula also contains glutathione, centella, ceramide NP and hyaluronic acid, so the ingredient blend pairs its featured actives with moisturizing components.

The 15 mL drop-form serum is applied directly to the face and pressed gently into the skin. Its micro-spicules give the application a distinctive feel, a brief tingling sensation may occur.

## Product specs
- Type: Facial serum
- Size: 15 mL / 0.50 fl oz
- Arbutin: 70,000 ppm
- Tranexamic acid (TXA): 40,000 ppm
- Micro-spicules: 60,000
- Other highlighted ingredients: Glutathione, centella, ceramide NP and hyaluronic acid

The formula is centred on arbutin and TXA, with glutathione as part of the ingredient blend. Centella, ceramide NP and hyaluronic acid add a moisturizing focus, helping skin feel comfortable as the serum becomes part of a broader routine. Rather than choosing a single-ingredient serum, this brings several highlighted ingredients together in one step. What makes the application different? The micro-spicules provide a distinctive serum experience, while the product remains a leave-on face-care step to press in gently.

## Practical tips
Apply a small amount evenly over the face, then gently press it in until absorbed. If you are new to spicule-based skincare, begin with a small amount a few nights a week and increase use as your skin adjusts. Follow with moisturizer, and use sunscreen during the day. The product is described for use in a daily routine, with a stated frequency of twice daily, introducing it gradually offers a practical way to find a comfortable routine. A primary skin irritation test recorded a score of 0.0, though individual responses can vary. Patch test before first full-face use, and stop using it if irritation persists.

## Best use cases
This serum suits a routine that already includes cleansing and moisturizing, with a targeted serum step in between. For example, after cleansing in the evening, apply a small amount over the face, press gently until absorbed, then finish with moisturizer. In a morning routine, pair the serum with daytime sunscreen as directed. Its compact 15 mL size also makes it a focused addition for shoppers who want to try an ingredient-rich serum without replacing their other routine steps.

## When it makes sense
It’s a good fit if you want a Korean skincare serum featuring specified concentrations of both arbutin and tranexamic acid, along with glutathione and moisturizing ingredients. The formula offers a multi-ingredient approach in one facial step, rather than building a routine around separate single-active serums. The spicule component is another reason to choose it when a distinctive application experience matters. For a straightforward routine, use it after cleansing and before moisturizer, introducing it gradually and keeping daytime sunscreen in the routine.
