skinbetter science Alto Defense Serum

Makes my skin look amazing.

Love it!!!

I've been using Alto Defense Serum for a few months, and my skin has never looked healthier. It feels smoother, looks more radiant, and I’ve noticed a significant improvement in my overall tone.

I love how this serum absorbs quickly without feeling heavy or greasy. My skin looks brighter, and it helps protect against environmental stressors. I will continue buying this!!

Best antioxidant serum! I’ve tried many antioxidant serums, but this one is by far my favorite. It gives my skin a beautiful glow and has helped even out my complexion.

Great for sensitive skin! My skin is easily irritated, but this serum is gentle and non irritating. It hydrates, smooths, and makes my skin look refreshed without any redness.

After just a few weeks of using this serum, my skin looks firmer, more hydrated, and overall healthier. It’s a must-have for anyone looking to improve their skin’s resilience!

Worth every penny! This serum is pricey, but the results speak for themselves. My skin feels stronger, looks more even, and I love knowing I’m giving it the best protection against daily stressors.

My all-time favorite Vitamin C serum

Another fantastic product from the SkinBetter Science brand! It's lightweight, non-greasy, and highly buildable. I'm incredibly happy with my purchase once again!

Absolutely adore this serum! It maintains a youthful appearance for my skin.

I previously used Alto Advanced, but I switched to regular Alto since I'm under 30. I'm pleased to say my skin is still glowing and free of breakouts.

I'm thrilled with the radiant effect this product provides!

I use the complete range of Skinbetter Science products, as recommended by my dermatologist and esthetician. My skin looks remarkably good for being 63 years old. Although the products are expensive and should be used sparingly, I have been using them for years and intend to continue doing so.

I can already notice a change in the texture of my skin after just a little use.

I absolutely adore this product. My face appears significantly brighter and healthier.

I absolutely love this serum! I've been using it for a few months now, especially after getting the SylfirmX treatment. I started with dry combination skin, and this serum, along with the Trio Rebalancing, has really helped my skin feel moisturized.

his is the best vitamin C product I've ever used. I can't imagine returning to my previous products. My skin looks brighter and more radiant.

I’m a big fan of this vitamin C serum. I've also tried Alto Advanced, and I find its texture to be a bit different. While I've heard that Alto Advanced offers more preventive benefits, it's quite pricey. The regular Alto is also expensive, but I like to alternate between the two. I love how Alto has significantly improved my skin's texture and reduced redness.

This serum is incredible! It has significantly improved my acne marks and overall complexion. It leaves your skin looking youthful and feeling refreshed.

I really like it! I've been very sensitive to vitamin C serums in the past, so I was quite nervous about trying this one. However, it hasn't caused any major issues so far, and I believe it has helped reduce redness.
