Hyaluronic acid (HA) is one of the most recognised skincare ingredients. It hydrates the skin by binding water, leaving it plump and dewy. But it is only one-dimensional — all it does is hold water.
Algica®, a silica derived from marine algae, does that and more. It hydrates like HA, but also cleanses, protects, and boosts other ingredients, which is why I chose it as one of the marine actives for my Oceanic Day Cream.
1. Where They Come From
- Hyaluronic Acid: Produced in factories by fermenting plant sugars like corn.
- Algica®: Extracted from marine algae in Sweden, grown in a process that absorbs carbon dioxide, cleans water, and produces by-products for animal feed and fertiliser.
2. What They Do for the Skin
- Hyaluronic Acid: Binds water to hydrate and plump the skin.
- Algica®:
- As hydrating as HA, proven in studies.
- Cleanses by absorbing oil, sweat, bacteria, and impurities.
- Protects against pollution, blocking more particles than HA.
- Boosts SPF by 9–13% when added to sunscreen.
- Enhances the performance of other active ingredients.
3. Environmental Impact
- Hyaluronic Acid: Relies on agriculture and industrial fermentation.
- Algica®: Produced in a way that reduces global warming and eutrophication, with a fully sustainable process.
Why I Chose Algica® Over Hyaluronic Acid
HA is effective, but Algica® offers more: hydration plus cleansing, protection, and boosting other actives. And it is created in a process that helps the planet. It’s the next step in multifunctional, sustainable skincare.
