Your questions, answered
What is silk protein?
Silk protein comes from the natural silk fibre spun by silkworms. For skincare it is broken down into smaller pieces, called hydrolyzed silk, so it blends easily into light, water-based formulas.
What does hydrolyzed silk do for skin?
It leaves a light, invisible film that helps skin feel smoother and softer to the touch, and helps hold moisture at the surface.
Why is silk hydrolyzed?
Whole silk fibres are far too large for a light formula. Hydrolysis breaks the protein into smaller fragments that dissolve easily in mists and creams.
Is silk protein suitable for sensitive skin?
Hydrolyzed silk is generally well tolerated. If your skin is reactive, try a small area first, and avoid it if you have a known silk allergy.
Is silk protein vegan?
No. Silk protein comes from silkworms, so Fresh Blossom Face Mist is not vegan. It is cruelty-free.
Will silk protein feel heavy or sticky?
No. In a face mist it feels weightless and leaves skin soft rather than sticky.
How do I use a face mist with silk protein?
Close your eyes and spritz the mist over your face from a short distance. Use it after cleansing and before your cream, or any time during the day to refresh.
Can I use silk protein with other ingredients?
Yes. In Fresh Blossom Face Mist it works alongside neroli, yuzu, hibiscus and aloe vera, and you can follow it with your usual serum or cream.
