It depends on your skin.... for dry skin, or thin skin, I'd opt for LA as it hydrates...
for normal to oily and thick skin, I'd opt for GA
for very oily or sweaty skin I'd opt for SA...
(Some people think they have thick skin, but isn't necessarily the case, one needs to really understand their skin before they can make such assumption)
Lighteners should always opt for the lotion.. it offers better coverage and evenness...
with peels you can skip an area without realising, and you'll need to wait for a week to correct it! unlike lotions,,, today you missed an area, you can cover up the next day....... (= even results)
