For skin protection, antioxidant defense, and eye health, this delivers **Astaxanthin** at 12mg per softgel — right at the top of the 4–12mg clinical range. You're getting a full effective dose in a single softgel, which is as high as most research protocols go. The source — Haematococcus pluvialis microalgae — is the natural form used in the majority of clinical trials.

Astaxanthin is a carotenoid antioxidant with moderate clinical evidence for reducing UV-induced skin damage, improving skin elasticity, and supporting visual comfort during screen use. What this means for you: the effects are cumulative, typically showing up after 4–12 weeks of daily use. The softgel format paired with sunflower seed oil supports absorption, since astaxanthin is fat-soluble.

One consideration: 12mg is the ceiling of the studied range, not the middle. Most positive skin trials used 4–6mg daily. You're getting more than you likely need, though no safety concerns have been reported at this dose.
