Bioactivity Stretch Marks Removal Cream with Glycolic Acid
The whole body stretch marks treatment with Glycolic Acid is rich in natural active ingredients that moisturize your skin deeply, protect its cellular structure and boost the skin repair process due to Bioactivity Extract that triples the antioxidant power of the Guam Seaweed. This powerful innovative formula helps to prevent the appearance of pregnancy stretch marks, helps with skin stretching during puberty, and visibly reduces the appearance of long-existing stretch marks.
Active Ingredients:
- GUAM Seaweed. (Chlorella Vulgaris green seaweed):
Rich in peptides and amino acids which are contained in human collagen. In vitro tests show that Chlorella Vulgaris stimulates the synthesis of collagen and elastin and reduce skin sagging; at the same time, it limits the action of the enzymes responsible for the degradation of these proteins that support the skin.
- Bioactivity extract:
Bioactivity extract is the result of a patented bio-liquefaction process that recovers the active ingredients from GUAM Seaweed in the form of highly available phytocomplexes. The extract obtained has an ORAR value of 1565 i.e., antioxidant power and ability to fight free radicals 3 times greater than the traditional extract (ORAC 400).
- Hydroglycolic extract:
Rich in minerals, trace elements and amino acids, this extract improves the skin’s hydration, promotes elasticity, suppleness, and softness. It is an excellent boy skin re-mineralizing and revitalizing agent.
- Glycolic acid:
Promotes the restoration of skin brightness, smoothness, and tone, reducing stretch marks and lightening pigmentation.

How a stretch marks removal cream works on old marks
New stretch marks are red or purple because the tissue is still inflamed and active. Over months they turn white and silvery: the skin over them is thinner and the collagen underneath has healed in a disorganised way. A plain moisturiser cannot reach that. Bioactivity combines gentle resurfacing with repair, so old stretch marks fade and the skin texture evens out.

Stretch marks after GLP-1 weight loss and in perimenopause
Losing weight fast leaves marks on belly, thighs and arms, and lower estrogen in perimenopause thins the skin so old marks show more. Twice-daily use resurfaces the marks and supports the skin while your body settles.
Pregnant or breastfeeding? Use the Inthenso Mom Stretch Mark Oil instead. For newer red marks, the Duo Stretch Marks Cream is gentler.

Your questions about this stretch marks removal cream
What women ask us before their first order.
Does a stretch marks removal cream work on old white marks?
It makes them less visible. Glycolic acid smooths the surface and the Bioactivity Extract supports repair, so marks look flatter and closer to skin tone. Old marks need at least two months.
How is it different from Duo Stretch Marks Cream?
Bioactivity contains glycolic acid for older, set-in marks. Duo is gentler, suits new red marks and can be used in pregnancy. Many women use Duo in the morning and Bioactivity at night.
Can I use it while pregnant or breastfeeding?
No, because it contains glycolic acid. Use the Inthenso Mom Stretch Mark Oil during pregnancy and breastfeeding, then start Bioactivity afterwards.
Can I go in the sun after using it?
Keep treated skin out of the sun and away from UV lamps after you apply it. Glycolic acid makes skin more sensitive to light. Use it at night if your marks are on exposed skin.
How long until stretch marks fade?
Skin feels smoother in about two weeks. Old white stretch marks look flatter and lighter after about two months of twice-daily use.
Does it work on stretch marks from weight loss and GLP-1?
Yes. Use it on marks on the belly, thighs, arms and breasts after weight loss, morning and evening, and keep going while your weight settles.
Does it help in perimenopause?
Yes. Lower estrogen thins the skin and makes old marks show more. Twice-daily use resurfaces the marks and keeps skin supple.
Will it sting?
It may tingle a little the first few days. Do not use it on broken or irritated skin. If it stings, use it once a day until your skin adjusts.
How long does one tube last?
The 150 ml tube lasts about a month used twice a day on a few areas.
What women say about the Bioactivity stretch marks cream
I was very skeptical about the effectiveness of this cream, but I've personally seen that by applying it morning and evening, my daughter's stretch marks have significantly diminished; some have become practically indistinguishable from the surrounding skin.
I've only used this for about a couple of weeks and I can already tell how much softer my skin is. It actually makes my stretch marks less visible.
I have been using it for two months and my skin is very toned... very satisfied I highly recommend it.
