Skinbetter Alto Advanced Defense and Repair Serum is a clinically proven antioxidant serum that goes far beyond standard vitamin C protection to defend against both environmental and internal sources of oxidative stress. Powered by two proprietary antioxidant technologies, this serum combines 19 antioxidants into a single, layerable formula that targets the visible effects of aging from every angle, including dullness, uneven tone, rough texture, and redness. It is formulated without parabens, fragrance, and dyes.

Key Benefits

Broad-Spectrum Environmental Defense A proprietary complex of 19 antioxidants, including tetrahexyldecyl ascorbate, ergothioneine, grape seed extract, green tea extract, turmeric root extract, and ubiquinone, works together to neutralize free radicals generated by UV exposure, pollution, and other environmental aggressors.

Targets Internal Oxidative Stress A second proprietary technology featuring pyrroloquinoline quinone (PQQ) allyl ester and superoxide dismutase addresses intrinsic free radicals produced by the skin's own aging process, supporting the skin's natural renewal and repair pathways.

Visibly Reduces Redness and Evens Tone Niacinamide, licorice root extract, bisabolol, and chlorogenic acids work in concert to calm visible redness, minimize discoloration, and promote a more uniform complexion over time.

Strengthens and Hydrates the Moisture Barrier A ceramide complex (ceramide NP, ceramide AP, ceramide EOP) paired with phytosphingosine, linoleic acid, linolenic acid, and hyaluronic acid reinforces the skin's barrier while delivering deep, lasting hydration.

Post-Procedure Compatible Clinically tested and shown to be well tolerated after non-ablative fractional laser treatments, making it a reliable choice during recovery when skin is most vulnerable to oxidative damage.

97% of patients reported brighter-looking skin after 12 weeks*

*Alto Advanced Defense and Repair Serum was evaluated in a clinical trial conducted by board-certified physicians in 39 patients of varying skin tones, following twice-daily use over 12 weeks.

If your skin looks dull, uneven, or fatigued despite a solid routine, this serum fills the antioxidant gap that most single-ingredient products leave behind. It is especially well suited for skin showing early or progressive signs of aging driven by sun exposure, pollution, or the natural slowdown of your skin's internal defenses.

Ideal for all skin types, including sensitive and reactive skin. Because it is fragrance-free, paraben-free, and dye-free, it layers comfortably under sunscreen and makeup without irritation. It is also a strong choice if you are undergoing professional treatments and need reliable antioxidant support during the healing process.

Apply this serum to completely dry skin before any other treatment products in your routine. Because it contains both oil-soluble and water-soluble antioxidants, applying it first on bare skin ensures the full spectrum of actives can absorb without competition from heavier layers.

Apply: Dispense a thin layer onto clean, dry skin and smooth over the face, neck, and décolleté.

Frequency: Use every morning and evening as part of your full skincare regimen.

Protect: Follow with a broad-spectrum sunscreen during the day for maximum defense against environmental damage.
