Tiam B3 Niacin Sunscreen — SPF 50+ PA++++ with niacinamide, in an invisible finish that suits every skin tone. 50ml.
The filter list is the interesting part: Mexoryl SX, Uvinul A Plus and Ethylhexyl Triazone — modern, photostable filters rather than the cheap standbys.
Product Overview
Tiam B3 Niacin Sunscreen is a broad-spectrum SPF 50+ PA++++ Korean sunscreen that also carries niacinamide, so it works on dullness and the look of dark spots alongside protecting against UV.
What sets it apart is the filter system, which Tiam publishes in full. It uses Terephthalylidene Dicamphor Sulfonic Acid (Mexoryl SX), Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) and Ethylhexyl Triazone — a modern, photostable set that holds up under sun exposure instead of degrading within the hour, which is exactly what a UVA filter needs to do. The finish is invisible, so it works across all skin tones without a cast.

How to Use
- Apply as the final step of your morning skincare, at least 15 minutes before sun exposure, as Tiam advises.
- Use around two finger-lengths for face and neck.
- Reapply every two hours outdoors, and after sweating or swimming.
Why Photostability Matters
A UV filter that degrades in sunlight stops protecting you partway through the day, which defeats the purpose. Older UVA filters were notoriously unstable. Mexoryl SX and Uvinul A Plus were developed specifically to hold up under exposure, and a sunscreen built on them keeps its rating for longer than the ingredient list of a cheaper formula would suggest. It is still not a reason to skip reapplication.
Patch Test First
Before using a new active on your face, try it on a small area — the inner forearm or just below the jaw — and leave it for 24 hours. Mild tingling on application is common with acids and settles; stinging, burning, redness that spreads, or itching that persists is not, and means the product is not for you.
Introduce one new product at a time. If three go on together and skin reacts, there is no way to tell which one caused it.
Frequently Asked Questions
Does it leave a white cast?
No — these are chemical rather than mineral filters, so it finishes invisible on all skin tones.
Can it replace my niacinamide serum?
It adds niacinamide rather than replacing a dedicated serum, but on a simple routine it does two jobs at once.
Why 15 minutes before going out?
Chemical filters need a short time to form an even film on the skin. Applying as you step outside means the first stretch is unprotected.
How should I store it?
Somewhere cool and dark, with the cap closed. Heat and light degrade actives — vitamin C and retinol especially — so a bathroom windowsill is the worst place in the house for them.
