When is it appropriate to start putting scar cream after breast augmentation? 2 weeks post-op.

I had breast augmentation two weeks ago. I am 15 days post op. when is it appropriate to start treating the incisional scar area?I don’t want to risk an infection if it’s not fully healed & closed up. I had a situation with my left incision a week ago where I bent to 1 side to pick something up from the floor & it started hurting like if i pulled on the incision. I think that caused more scarring & highly irritated my incision . I dont want to cause any further damage.
