What it is
Hakka is a fermented botanical complex derived from a traditional Korean herbal formula. It is produced through a controlled fermentation process that breaks down plant compounds, potentially making them more bioavailable for the skin.
How it works
Hakka works by delivering a mix of antioxidant compounds from the fermented herbs, which can help neutralize free radicals on the skin's surface. The fermentation process may also produce peptides and organic acids that support gentle exfoliation and a balanced skin microbiome.
Pros
Gentle on skin
Hakka is generally well-tolerated and unlikely to cause irritation, making it suitable for sensitive skin types.
Microbiome-friendly
As a fermented ingredient, Hakka may help support a balanced skin microbiome, which is linked to healthier-looking skin.
Cons and cautions
Limited research
There are few peer-reviewed studies on Hakka specifically, so its benefits are less proven compared to well-studied antioxidants.
Variable quality
The potency and composition of Hakka can vary between brands and batches, making it hard to predict consistent results.
Best for
