Useful if: choose it if you want a PDRN serum with a clear retinol angle and a pump format rather than a simple hydrating PDRN serum.
Innisfree describes its Green Tea PDRN as a vegan, green tea derived alternative to traditional salmon derived PDRN. The serum also includes a retinol complex, so the product is not simply a hydration serum.
That combination makes it more relevant to shoppers comparing retinoid serums than to someone who only wants a gentle PDRN moisturising step.
The brand and UK retailers advise starting cautiously if you are new to retinol and using sunscreen in the morning. Retinoids can irritate some skin types, especially when several active products are used in the same routine.
Retinoids are generally avoided during pregnancy and breastfeeding unless a qualified professional advises otherwise.
Use it at the serum stage, then follow with moisturiser. If you already use a separate retinol or retinal product, adding this on the same evening may be unnecessary.
