Year-Round Daily Defense
Frequently Asked Questions
What makes Alto Defense Serum different from other antioxidant serums?
Alto Defense Serum goes beyond standard Vitamin C formulas by combining Vitamins C and E with 17 additional antioxidants, botanical polyphenols, and peptides. This comprehensive blend provides broad-spectrum defense against oxidative stress from multiple environmental sources, not just UV rays.
Can this serum help with redness?
Yes. Alto Defense Serum includes a skin-soothing blend with licorice extract and calming botanicals to visibly reduce redness while promoting a more even skin tone. It’s suitable for skin that’s prone to irritation or environmental sensitivity.
Will it brighten my complexion?
Absolutely. In addition to its protective effects, Alto Defense Serum helps improve overall luminosity. Antioxidants and licorice extract work together to minimize dullness and promote a brighter, more radiant appearance with daily use.
Is it suitable for all skin types?
Yes. This serum is formulated for universal use and works well on dry, normal, combination, and oily skin types. Its lightweight texture makes it easy to layer under other skincare products without feeling heavy or greasy.
What’s the difference between Alto Defense Serum and Alto Advanced?
Alto Defense Serum is the original formula, offering daily antioxidant protection with vitamins C, E, and 17 additional antioxidants to help reduce redness and improve uneven skin tone. Alto Advanced builds on this base, adding a newly patented antioxidant and extra free-radical fighters for even more comprehensive defense and brighter results.
