I tried, add
Protec™ OX 0.05% and
Protec™ UV 0.03% It appears that in just 2 days the color has started to change. go brown The color changes very quickly. The controlling factors are temperature (room temperature vs refrigerator) and light in both total darkness. As noticed - if not add
Repair Activator™ in the formula (in The formula only contains
Retinal ) Leave for about 1 month in room temperature, opaque container, color will gradually turn brown. - The part in the formula that is added
Repair Activator™ 10% Leave it for about 2 days in room temperature. The container is opaque. The color changes very quickly. From the problems encountered, how should they be solved?
