Most of our products are vegan. Our Lip Tonics and Dream Cream contain beeswax.

Yes. Most of our products are packaged in glass, easily and commonly recycled. We use recyclable PET plastic for our family products which is safer for children.

We encourage upcycling rather than recycling! Our bottles and jars make sweet vases, oil bottles, hair clip holders, spice jars, & more.

As far as we can, we use recyclable caps and dispensers. Currently, pumps are non-recyclable.

Unusually for brands in our category we have chosen to box our products in plain outers made from recycled FSC approved brown cardboard. Pretty outer packaging is lovely, but it so often goes straight in the bin, so we see it as a waste of resources. It also means we would need to pass the cost on to you. 

We ship our products in fully recyclable materials and our mailing boxes are made from 100% recycled card. 

Our products are formulated for all skin types, including sensitive skin. However, it is always a good idea to test a new product on a small patch of skin before using it liberally. If any undesirable effects occur, stop using immediately & consult a medical professional.

Yes, we've created our collection to work for all women. All Sister & Co. products are safe to use when pregnant and while breastfeeding.

There are some essential oils that should be avoided during pregnancy, but our products that contain essential oils contain them at levels compliant with EU Regulation 1223/2009, meaning that qualified safety assessors have deemed finished products entirely safe for use for all consumers - including women who are wishing to become pregnant, pregnant women and breastfeeding women.

If you have any concerns around using essential oils during pregnancy, please consult your midwife or medical professional before using our products.
