TIA'M Vita B3 Source Serum — Niacinamide 10% + Arbutin 2%, 1.35 fl oz Lightweight Brightening Daily Serum for Dark Spots

TIA'M Vita B3 Source Serum is a lightweight, water-based brightening treatment with 10% niacinamide and 2% arbutin designed to help even skin tone and reduce the look of dark spots while absorbing quickly into the skin.

This daily facial serum blends a high concentration of niacinamide with arbutin and soothing allantoin to target uneven tone, post-acne marks, and dullness without a heavy finish. Formulated in Korea and completed with skin irritation testing, the serum aims to fit smoothly into morning and evening routines and layer with other skincare staples.

How does this serum help even skin tone and tackle dark spots?

The formula combines 10% niacinamide and 2% arbutin to address pigment irregularities and brighten the complexion. Niacinamide supports skin barrier function and overall clarity, while arbutin works as a targeted brightening agent. Together they create a complementary approach to reduce the visible contrast of dark spots over time.

• 10% niacinamide concentration for visible tone improvement
• 2% arbutin to help minimize hyperpigmentation appearance
• Water-based base ensures rapid absorption and non-greasy feel

Is this serum suitable for daily use and mixing with other products?

The lightweight, fast-absorbing texture makes it easy to layer under moisturizers, sunscreens, and most active serums. It’s formulated for both AM and PM use, though sunscreen is recommended during daytime when using brightening actives. Because it contains a high niacinamide level, introduce it gradually if you have sensitive skin.

• Use mornings and nights; always follow with SPF in daytime
• Pairs well with hydrating serums and lightweight creams
• Start with alternate-night application if you’re new to concentrated niacinamide

What texture and sensory experience can I expect?

TIA'M Vita B3 Source Serum is water-based and absorbs quickly without leaving a sticky or heavy residue. The formula includes allantoin to support skin comfort and a smooth finish, making it comfortable for layering. Its subtle, lightweight feel works under makeup and does not pill when used correctly.

• Fast-absorbing, non-greasy liquid texture
• Contains allantoin for a soothing, smooth sensation
• Designed to layer seamlessly with sunscreen and moisturizers

What testing and ethical considerations support this product?

The serum is a vegan Korean skincare product that has completed a skin irritation test to help ensure tolerance for many users. A clinical study in Korea involving 22 women measured improvements in skin clarity; results can vary individually. The formulation avoids animal-derived ingredients and focuses on gentle brightening performance.

• Vegan formulation with skin irritation testing completed
• Clinical testing on skin clarity with documented participant data
• Thoughtfully developed to balance potency and comfort

Who is this for: TIA'M Vita B3 Source Serum is for people seeking a potent yet lightweight brightening step to reduce the look of dark spots, even skin tone, and enhance overall clarity. It suits those who want a fast-absorbing, layerable serum in both morning and evening routines, and who prioritize vegan, thoughtfully tested Korean skincare. If you have highly reactive skin, consider patch testing or introducing the serum gradually.
