Hey hun I’ve been using kelo-cote-scar-gel-15g for a few months now as advised by my surgeon bur she said to use it for upto a year post op. So 15 wks is still quite early! Usually when trying products it can take threw months for them to make a change or ur skin to get used to it.
Six months post op mine were still quite pink around my nipple and my incisions on the crease are still quite dark but it really does take time.
Natural moisturisers like shea or cocoa butter do help to lighten the skin but make sure they’re 100% natural or have the ingredient listed quite close to the start as this indicates higher concentration of it.
Bio oil contains a lot of synthetic chemicals which I’d steer clear of and arnica cream is for bruising not scars.
Apply a high factor or total sun block when on holiday or in the sun because sun damage will make the scarring darker. Kelocote also do a silicone gel with spf 30 in it.
