The 2 main reasons to use alpha arbutin are for skin lightening and covering blemishes from skin discoloration. If you’re trying to lighten your skin, start off with a 2-month supply (around 25 grams (0. 88 oz)) so that you can make adjustments to your skin lightening formula once you find what’s working for you.
You need 5-parts water for every 1-part alpha arbutin. To determine how much you need, multiply the amount of arbutin by 5 and convert it to milliliters. For example, if you’re using 25 grams (0. 88 oz) of arbutin, multiply it by 5 to get 125 grams (4. 4 oz). This converts to 125 millilitres (0. 53 c) of water.
If you’re worried about making a mess, use a funnel to pour the mixture.
You cannot mix arbutin into an oil-based cream or lotion since the oil and water won’t mix evenly.
Alpha arbutin can be quite strong on its own and cause a burning or stinging sensation if it takes up a high percentage of the lotion or cream. For example, if you have 200 millilitres (0. 85 c) of skin care lotion, add 1 mL (0. 0042 c) of dissolved arbutin. If you have a facial cream, add 4 millilitres (0. 017 c).
Since arbutin is water soluble, it should mix quite easily into the lotion or cream.
