Frequently Asked Questions

  • Yes, all Saya Skin products are safe for use during pregnancy and breastfeeding. However, with new products, it is always recommended that you consult your healthcare professional for personalised advice, as your skin can become more sensitive during and/or post-pregnancy.

  • Older stretch marks that appear silvery or white lines often reflects inflammation that has settled for a while and scarring of the tissue. The body oil may help improve the appearance of stretch marks with consistent, long-term use but results can vary between individuals, as some older stretch marks may be more resistant to fading. Read our blog for more information on managing stretch marks.

  • Kerzon uses natural laundry soap made from plant-based oils instead of synthetic detergents. For more information, see our article on Laundry Soap vs Detergent.

  • Yes, Kerzon is gentle and suitable for sensitive skin. 

    Recent studies have shown that many regular laundry detergents, especially those containing harsh surfactants like SDS (sodium dodecyl sulfate), can weaken the skin barrier, increase water loss, and trigger inflammation. This happens because small traces of these detergents often remain on clothes and stay in contact with your skin all day. 

    Kerzon works differently. It’s made with true natural soap from saponified olive and coconut oils, without those aggressive surfactants. It cleans effectively but rinses much cleaner, making it far gentler on both skin and fabrics. 

    If you have very sensitive skin or specific concerns, it’s always a good idea to do a small patch test first.  

  • Yes, you can use it for handwashing. Just add 1–2 caps to a basin of lukewarm water, gently agitate the garments, and rinse thoroughly.
