SkinBetter Science Alto Advanced Defense and Repair Serum Reviews

I have noticed my skin looks brighter and healthier since starting to use this. It absorbs quickly and works well under makeup. My skin definitely feels smoother, and I haven’t noticed irritation. No fragrance as well which I appreciate.

Just received first purchase and happy with initial results. Excited to see long-term benefits

I love this product and have been using for about a year now. Whenever I run out I definitely can’t live without it. It’s a perfect start to my morning regimen and helps my skin feel and look great

If you duffer from uneven dull skin this is for you!

The perfect skin product for daytime use. I am over seventy and This product has seriously increased a more youthful appearance and made my skin look healthier!

Just switched to this Vitamin C serum & like it! I have used other Skinbetter products & they're great. I had a reaction from another brand, so have switched to this one & am excited to use it!

Obsessed ever since I was introduced. I tried using other Vitamin C but had to go back because every else is inferior.

The product itself is amazing. However, the customer service is awful, and it takes over a week to ship the product. I ordered from a third party and it came in 3 days. I ordered directly from the website because I wanted to make sure the product was stored properly. After talking to customer service I wouldn't trust ordering from this website, I'd just do a third party and save money.

I like knowing that I am applying a product that is protecting my skin.

after about 4 months the color started changing to deep yellow and now everytime I put it on during the day I have this deep mustard tan on my face (not good). I understand that the color can slightly change but this is veryy obvious and hideous change for such an expensive product. What is the solution? Thank you

I love my products and have used them for years. I spent over $600 and didn't get my free gifts.

Arrived very quickly. This product was sealed and fresh.I appreciated the thoughtful samples. I will most definitely order from them again.

Ive tried so many Vitamin C serums over the years and Alto Advanced Defense Serum is by far my all-time favorite. My skin looks brighter and feels smoother.

This serum is like liquid gold on my skin. In a week it gave me a gorgeous glow and helped repair my skin barrier without any irritation.

This vitamin C is absolutely amazing. Ive only been using it for a week and my skin already looks more even and clear. No adverse reactions and highly recommend.

I absolutely love this product and have repurchased multiple times. The 15 ml size lasted me nearly three months and the 30 ml size lasted five months.

I am enjoying using this serum. It feels light, has a mild scent, and does not leave my skin greasy. Hoping to see full results by week five.

AltoDefense I liked best. Its like a light lotion that absorbs well and has tons of great ingredients. I sometimes found it a bit irritating but it cleared up.

Ive been using Alto Defense Serum for a few months and my skin has never looked healthier. It feels smoother, looks more radiant, and tone is more even.

I love how this serum absorbs quickly without feeling heavy. My skin looks brighter and it helps protect against environmental stressors.

Best antioxidant serum Ive tried. It gives my skin a beautiful glow and has helped even out my complexion.

After a few weeks of use my skin looks firmer, more hydrated, and overall healthier. Its a must-have for resilience.

I love that it not only helps with pigmentation but also protects my skin from environmental damage. It is a game-changer in my routine.

Absolutely love this product. It replaces my vitamin C serum and makes my morning routine quicker. The pump gives the exact amount every time.

This serum works well to defend against oxidative stress. My skin barrier feels stronger and redness is noticeably reduced.
