Astaxanthin

Astaxanthin skincare is often chosen for dull, uneven-looking skin and daily antioxidant support. This collection brings together serums, cleansers, sunscreen, and treatment masks that pair astaxanthin with tone-supporting actives such as niacinamide, tranexamic acid, peptides, and glutathione where present in the live assortment.

Some formulas lean brightening, while others sit in daily maintenance categories such as foam cleanser or UV protection, so the page stays ingredient-led rather than tied to one narrow concern. Because the assortment includes both rinse-off and leave-on formats, it works well for layering a steady routine instead of chasing aggressive resurfacing.

At Protoclinical, we use this page as a focused protocol edit for shoppers looking to support radiance, smoother-looking tone, and a more resilient daily routine with evidence-led Korean skincare.
