Strawberry legs. Got due to weight loss?

if your strawberry legs is Keratosis Pilaris... then yes you an use xerina... however that won't work on your stretch marks. 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 on the planet available which is can improve it 100% unless you surgically remove those parts of the skin. Get an online consult privately with pictures or meet a dermatologist directly for a proper evaluation of the condition. Hope this was helpful.
