Works well with
RetinolРетинол
MAP is stable at neutral pH, so there is no pH conflict with retinol. On sensitive skin this pair tolerates better than L-AA + retinol: no need to alternate.
RetinaldehydeРетиналь
MAP works gently at neutral pH, so it is compatible with retinal. A good choice for sensitive skin that cannot tolerate L-AA plus a retinoid in one routine.
