TIA'M Vita B3 Source Serum is a lightweight daily facial serum combining 10% niacinamide and 2% arbutin to help visibly even skin tone and reduce the appearance of dark spots.

This water-based formulation targets uneven skin tone, dullness, and dark spots with a high-concentration niacinamide blend paired with arbutin, while supporting skin comfort through soothing ingredients. Fast-absorbing and non-greasy, it’s built for easy layering in morning or evening routines and designed as part of a vegan Korean skincare regimen.

How does TIA'M Vita B3 Source Serum address uneven skin tone?

The serum uses a combination of 10% niacinamide and 2% arbutin to help improve the appearance of discoloration and uneven tone. Niacinamide supports overall clarity and texture, while arbutin targets hyperpigmentation-related concerns for a more balanced look.

• 10% niacinamide concentration for skin-brightening support
• 2% arbutin for targeted pigment care
• Water-based delivery for quick absorption into the skin
• Non-greasy finish that layers under moisturizers and sunscreen

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

Yes — the lightweight, fast-absorbing texture allows morning and night application and makes the serum easy to combine with other steps. Because it’s water-based and non-sticky, it sits well under creams, oils, or makeup.

• Apply after cleanser and toner, before heavier treatments
• Compatible with most moisturizers and sunscreens
• Designed for both AM and PM routines
• Avoid mixing with highly acidic exfoliants on the same layer to reduce irritation risk

What skin comfort and safety features does this formula include?

The formula adds allantoin to support hydration and soothe the skin, helping to balance the potent actives. It is a vegan formulation and completed a skin irritation test to help promote comfortable use, though individual reactions can vary.

• Allantoin for hydration and smoothing
• Vegan-friendly ingredient selection
• Skin irritation test completed; follow personal patch testing
• Non-greasy, water-based texture for sensitive layering

What results can I realistically expect and how was the product tested?

The serum was clinically tested in a small study involving 22 women in Korea for improvements in skin clarity; individual outcomes will differ depending on skin type and routine consistency. Regular, continued use and sun protection are important for visible improvements in tone and spot appearance.

• Clinically tested for clarity in a 22-person study
• Results depend on routine, sun exposure, and individual skin
• Pair with sunscreen in daytime to protect results
• Consistent use over weeks recommended for best outcome

Who is this for: TIA'M Vita B3 Source Serum is intended for people looking to brighten dull skin, reduce the visible look of dark spots, and even skin tone with a daily, fast-absorbing treatment. It’s suitable for those who prefer vegan Korean skincare and want a non-greasy serum that layers easily into both morning and night regimens. Individuals with very reactive skin should patch-test and introduce potent actives gradually.
