Sustainable beauty, tested

Beauty that doesn’t cost the earth.

Clean formulas, honest sourcing, and the brands actually doing the work, not just the packaging. I test everything before I recommend it.

    An amber dropper bottle and a bamboo-lidded jar on a stone slab in soft light

    The kind of product that gets a verdict. Demo photo.

    01
    How I test

    One verdict, one score, and three months behind it.

    i.

    Read it first

    The ingredient list and every claim on the label, checked against each other.

    ii.

    Live with it

    It goes into my own routine. I note the packaging, the refills and how it wears.

    iii.

    Make the call

    One verdict, one score out of 5, and the reason, written down.

    Swap guide

    What’s in your cabinet?

    Three changes that cut waste or cut the nasties, and cost about the same. Tap what you use and I will show the swap.

    Try this instead

    Three swaps in the guide. Pick what is in your cabinet and I will narrow it down.

    About Aster

    I left a corporate beauty job when I realized how much greenwashing I was helping sell.

    Now I test every product myself and only recommend what actually holds up, for your skin and for the planet.

    Seven years of testing sustainable beauty.
