Retino a gel over marks daily once application Apply only if u are not pregnant or planning pregnancy

The treatment depends on what stage of progression is the stretch mark. If it is in the early stage with red marks then we can try for improvement with just creams. If it is white creams alone wouldn't be enough and you would need multiple sitting of CO2 laser combined with PRP treatment with which we can hope for certain 60-70% improvement. There is no treatment which can improve it 100% unless you surgically remove those parts of the skin. You should send me images through private online consult for a better assessment of the problem and approaching it accordingly. Hope this is helpful.
