please i beg you, keep your candle out of direct sunlight
it is very normal for your soy candle to acquire a bit of dust over time, simply wipe over with a soft cloth or buff off with your finger to remove.
frosting is inevitable when using natural products
your candle may appear freckled or have a white coating amongst the colour
it does not affect either the quality of the burn or the candle itself. in fact it shows you that you have a piece made with great quality ingredients, without all of the nasty additives that make coloured candles look "perfect"
If you would prefer a candle with minimal markings, the cream colour will be perfect for you as it is less likely to freckle.
have a look @in_theorie instagram highlight to see some examples of candles with "frosting" before purchasing
