Having Scars On Forehead And A Dark Abrasion Scar. Using Propolis Bee. Can I Use Placentrex Gel. Suggest Effective Remedies.

I'm a 26 yr old male with a pearly fair complexion. However, recently 2 scars on my forehead have changed the way I look and are marring my otherwise handsome features! The first scar on the side of my forehead was caused by an insect bite and it has lightened somewhat, though still pretty visible. However, jst about a month back I got a bad abrasion scar on the center of my forehead as my head accidentally grazed against a taut coconut rope in the garden. It didn't bruise and there was hardly any bleeding, but, the skin has gotten almost scorched and signed and it has left an awful looking dark abrasion scar. I've tried Mederma, but, instead of helping lighten d scars it actually made them redder. So, I've stopped Mederma. I've been applying a Propolis bee concentrate which seemed to have somewhat lightened the insect scar,but, nothing seems to work on the abrasion scar. I've also been applying pure lemon juice on the scar areas. I've considered getting Bio Oil,but, it isn't available in India. I would like to know if Placentrex gel would work in at least removing the redness/darkness and/or any other effective remedies you may suggest. Thank you for your advise in advance!
