Another Purito like incident, but at least Purito took responsibility for it. Both filters are confirmed less than 1% each which may score less than Purito SPF 19-28. Niacinamide is typically around 2% for Korean ingredient list, and both filters were listed after niacinamide. You can use this for indoor spf, but keep searching for a different one. I wouldn't trust Green Cos manufacturing because both Hygee and Keep Cool are in the same boat of low percentage filters that can never reach spf 50.
