Hello,
Creams containing alpha hydroxyl acids and retin-A are said to be useful in decreasing the stretch marks but the advertised antimarks creams have no proof of effectiveness. Eat healthy ,nutritious food ,drink plenty of fluids and do moderate exercises. Laser therapy, and dermabrasion, alone or in combination have also been shown to be effective in diminishing the appearance of stretch marks.For that you need to consult a dermatologist.
Hope it helps.Take care and pls do keep me posted on how you are doing or in case you have any additional doubts.Kind regards.
Fractional laser resurfacing helps.About other treatments, best let nature heal.
