Two needs, one expertise

Two formulas for two specific needs: preventing or fading stretch marks.

[ SCIENCE FIRST ]

A universal concern, almost forgotten by research

At KOUAGA, we have chosen to document, measure and share our results with complete transparency.

~50 to 90%¹

of pregnant women develop stretch marks

~40%²

of men and teenagers have stretch marks

< 0.02%³

of global clinical research is dedicated to them

[ FOR EVERY CHANGING SKIN ]

Your skin deserves attention

Stretch marks appear during physical or hormonal changes. Our skincare supports each of these moments of life:

  • Pregnancy and postpartum: a treatment compatible with pregnancy and breastfeeding, to be applied from the first months.
  • Adolescence: growth spurts often mark young people's skin.
  • Sport and muscle gain: rapid muscle gain also puts strain on the skin.
  • Weight changes: whether gain or loss is rapid, the skin deserves appropriate care.
 Everything about stretch marks

FAQ

Your questions

Our pharmacist answers the most frequently asked questions about our skincare and stretch marks.

When should I start the prevention cream during pregnancy?

Ideally as soon as you find out the good news, before the skin starts to stretch. Apply morning and evening, regularly, to the belly, breasts, hips and thighs. The prevention cream supports the skin throughout pregnancy, then postpartum. Regular application is essential.

Are KOUAGA products compatible with breastfeeding?

Yes. The tolerance of both our products has been validated by toxicological assessment for all populations, including during pregnancy and breastfeeding. As a precaution, simply avoid applying the cream to the nipple and areola.

Prevention or fading: which cream should I choose?

The prevention cream is used before stretch marks appear, when the skin is subjected to rapid stretching or hormonal changes. The fading cream is dedicated to recent, red or purple stretch marks. The two complement each other: discover our Discovery Bundle.

How long before I see results?

Regularity is essential: apply morning and evening for several months (at least 4 to 6 months for the fading cream). Results will only be visible on recent, red to purple stretch marks. Our clinical studies measure these effects precisely; their results will be published in early 2027 on our Clinical evidence page.
