The ordinary's vitamin c suspension 23% is pretty solid for like £5-6, though it's grittier texture-wise so you gotta shake it well. if you want somthing smoother i'd go with the inkey list's vitamin c serum which runs around £25-30 and has that same brightening effect without feeling as heavy on skin. neither will be *exactly* like the drunk elephant since that's got the fermentation complex they charge extra for, but statistically you're getting 80% of the results for like 50% of the price which aint bad considering i'm spending that saved money on my morning run gear instead lol
