as far as trying to reduce the appearance of stretch marks, that isn’t possible (regardless what companies advertise). Nutrition can help them fade/strengthen the skin but they are permanent. I like consuming lots of collagen and omega 3 fats and hydrating a lot while eating plenty of dark green leafy veggies!
To prevent stretch marks during pregnancy, you just want to keep your skin hydrated and nourished so follow the tips above and then you can use shae butter, apricot or almond oil or jojoba oil on the belly twice per day! Lastly, you can add rosehip oil to the main oil you are using and massage it into the belly for extra protection 🙂
Yes chlorella is safe but choose a brand that is tested to be heavy metal and toxin free and do smaller doses at a time 🙂
