Consider this the gold standard of antioxidant protection. The Skinbetter Science Alto Advanced + Defense Serum is a award-winning, clinically validated antioxidant serum that has become a cornerstone product for patients who are serious about protecting and improving the overall health and appearance of their skin. It is the kind of product that does so much, so consistently, that once you start using it, it becomes difficult to imagine your routine without it.
 
What It Does
The Alto Advanced + Defense Serum is powered by a proprietary blend of 19 antioxidants, including vitamins C and E, working together to defend the skin against environmental damage caused by UV exposure, pollution, and free radicals. Unlike many vitamin C serums that can be unstable or irritating, this formula is uniquely engineered for both potency and stability, meaning the antioxidants remain active and effective from the first pump to the last. Beyond protection, the serum also works to visibly brighten the complexion, improve skin tone and texture, and support the skin's natural collagen over time.
 
Who It's Best For
This serum is truly for everyone. Whether you are in your twenties looking to get ahead of sun damage, or further along in your skincare journey and focused on reversing the signs of aging, the Alto Advanced + Defense Serum belongs in your routine. It is particularly well suited for patients who spend time outdoors, those dealing with uneven skin tone or dullness, and anyone who wants a reliable, physician-grade antioxidant working on their behalf every single day.
 
When to Use
Apply every morning after cleansing, as one of the first steps in your routine before moisturizer and sunscreen. Dispense one to two pumps into your palm, warm between your fingertips, and press gently into the skin. Follow immediately with SPF for maximum protection.
