Prevention is better than cure with these delightful scars.
Keeping your skin in tip top shape including regularly exfoliating and moisturising will help reduce the chance of them appearing.
However their colour will be the first sign of the likelihood of being able to improve their appearance.
If your stretch marks are white or shiny silver in appearance, they are VERY difficult to improve. If they are red or pink in appearance you have more chance of improvement in their appearance with the use of lasers, as there is still blood flowing to the area.
As with pore minimising creams, stretch mark creams will have little or no impact.
Not to be confused with scar creams. Stretch marks and scars are very different things. Scars can definitely be improved.
Really the only treatment that will have any impact is Fractional Co2 Laser as it reaches a lot deeper rejuvenating and stimulating the collagen to smooth out and reduce the scars.
