We consider a weak measurement reversal proposal to recover quantum correlations of two-qubit system under local amplitude damping channels. With weak measurement reversal, we show that quantum correlations do not vanish but preserve a finite value in the limit of the noise strength $$p\rightarrow 1$$ , which can be attributed to the probabilistic nature of this method. The experimental feasibility of this approach is also discussed in pure optical systems.
