Skin-Friendly Algae Alternatives

Hasanuddin University researchers are studying natural, algae-based ingredients as sustainable alternatives for skincare formulations. As the skincare market grows, brands and scientists are increasingly seeking eco-friendly ingredients that are biodegradable, responsibly sourced, and safer for long-term use; driving interest in replacing harsh or resource-intensive synthetic components with materials derived from nature.

Humectants are "essential ingredients in skincare, as they attract moisture and help keep skin hydrated while supporting the skin’s natural barrier. Common synthetic humectants, such as glycerol and hyaluronic acid, are effective but raise concerns related to sustainability and sourcing." As a result, researchers are exploring plant- and algae-based options.

Led by Professor Indah Raya, the Hasanuddin University team examined nanocellulose derived from the green algae Caulerpa racemosa. This algae is abundant in Indonesia and can be processed into a biodegradable material with strong water-absorbing properties. The research highlights its potential as a responsible moisturizing ingredient.
