SUNGBOON EDITOR Active Marine Astaxanthin Serum 30ml — Korean Antioxidant Brightening Serum with Astaxanthin and Glutathione
The Active Marine Astaxanthin Serum is the antioxidant-and-brightening hero of SUNGBOON EDITOR’s Astaxanthin line — a concentrated serum built around astaxanthin, one of the most potent antioxidants used in skincare. Delivered in a stabilizing capsule system and backed by a serious brightening stack — glutathione, tranexamic acid, niacinamide and ferulic acid — it targets dullness, uneven tone, dark spots and the oxidative stress that ages skin.
Astaxanthin is a deep-red marine carotenoid (from Haematococcus pluvialis algae) with antioxidant power far above most vitamins. This serum pairs it with sea buckthorn, hydrolyzed pearl, peptides and a full antioxidant network for radiance and protection in one step.
What the Astaxanthin Serum Does
- Fights oxidative stress. Astaxanthin, ferulic acid, vitamin E, fullerenes and beta-carotene form a layered antioxidant defense against the free-radical damage behind dullness and premature aging.
- Brightens and evens tone. Glutathione, tranexamic acid and niacinamide are three of the best-known ingredients for dark spots, uneven tone and overall radiance.
- Firms and smooths. Hydrolyzed collagen, hydrolyzed pearl and a peptide blend (copper peptide, Matrixyl) support firmness and a luminous finish.
- Hydrates and soothes. Hyaluronic acid, beta-glucan, ceramide NP and alpha-bisabolol keep skin calm and comfortable.
What an Antioxidant Serum Can and Can’t Do
Antioxidants like astaxanthin are genuinely valuable — but it helps to be clear on how. They work mainly to prevent and slow damage: neutralizing the free radicals from UV and pollution that dull skin and break down collagen over time. The brightening ingredients (glutathione, tranexamic acid, niacinamide) do gradually fade uneven tone and dark spots, but over weeks of consistent use, not overnight. And antioxidants work best with daily sunscreen, not instead of it — they reduce the damage that gets through, while SPF blocks it at the source. Used together and given time, the glow is real.
Who the Astaxanthin Serum Is For
- Skin that looks dull, tired or lacking radiance
- Uneven tone, dark spots or early sun damage you want to brighten and prevent
- Anyone who wants antioxidant protection against pollution and photoaging
- Those building an anti-aging routine focused on glow and prevention

Frequently Asked Questions
What is astaxanthin and why is it in skincare?
Astaxanthin is a deep-red antioxidant carotenoid that comes from marine algae, and it is one of the most potent antioxidants used in skincare — stronger than many common vitamins at mopping up the free radicals from UV and pollution that dull skin and break down collagen. In a serum it works mainly to protect and prevent, helping skin stay bright and resilient over time. Its natural red colour is why the serum has a soft coral tint.
Will it fade my dark spots?
It can help, gradually. The serum combines three well-known brightening actives — glutathione, tranexamic acid and niacinamide — which work on uneven tone and dark spots over weeks of consistent use, not overnight. Astaxanthin and the other antioxidants also help prevent new pigmentation from forming. For the best results, use it daily and always wear sunscreen, since sun exposure is what drives most dark spots in the first place.
Can I use it with vitamin C or retinol?
With vitamin C, yes — antioxidants layer well together and the ferulic acid here is often used to stabilize vitamin C, so they complement each other for daytime brightening and protection. With retinol, use them at different times — this serum in the morning, retinol at night — to keep things gentle, especially at first. Whatever you pair it with, morning use needs sunscreen on top.
Will the coral tint stain my skin?
No. The soft coral colour comes from astaxanthin itself, which is naturally deep red, but it absorbs into the skin without leaving a stain or tint behind. It will not affect your makeup or leave colour on skin or clothes once it has absorbed. If you ever notice a faint cast, a moment of massaging it in resolves it.
Should I get this serum or the Astaxanthin Capsule Cream?
They are different steps that work together. This serum is the concentrated treatment — lighter, with the brightening and antioxidant actives plus peptides and pearl. The Capsule Cream is the moisturizer that seals the routine, richer and with added PHA, CoQ10 and nourishing oils. For the fullest effect, use the serum then the cream. If you only want one, choose the serum for active brightening or the cream if your main need is a brightening moisturizer.
