Even though the serum will be somewhat protected from light in a dark glass bottle, you can also wrap the bottle in tin foil to make sure that no light can get to the serum at all.
Do not use the serum if you notice any redness or a rash after using it. If you notice any burning or tingling, then you may want to add a little more water to the serum to reduce the acidity.
If you notice any tingling, burning, redness, or other reaction to the serum, wash it off right away and do not use it again.
