0606-amber-heard-injury-tmz-02Two concierges in the building where Amber Heard and Johnny Depp lived claim they saw no bruising on her face, even noticing her flawless complexion ... days after Heard claims Johnny Depp hurled an iPhone at her.

We're told on Monday, May 23 -- 2 days after the alleged attack -- the daytime concierge saw Amber in the lobby, appearing to wear no makeup, and says there was no evidence of any facial bruising.

A woman who lives in the building tells TMZ, after Amber's allegations surfaced, the concierge told her not only did Amber appear bruise-free, the concierge added, "I was about to compliment her on her complexion."

The resident also says a second concierge told her the same thing. He saw Amber on Wednesday, May 25 -- appearing to wear no makeup and again appearing bruise-free.

We're told Depp's team may call the 2 concierges to testify later this month, during the trial for a restraining order.
