Pricy, but Worth It

My skin has a lot of sun damage and is losing tone. I've been using this serum for several weeks, and I think the texture looks smoother, and my skin feels very soft. I gave it 4 because I don't know yet if the sun damage will become less noticeable. I love the other Alastin products and am optimistic about this one helping slow the loss of firmness and improve the dark spots. A little goes a long way, so yes, the cost is up there, but one bottle seems to last a good while.

Perfect Vitamin C serum

Very gentle, but so effective. Just a small amount is needed and doesn't pill but stays smooth under makeup. Alastin makes wonderful skincare products.

Great Product

I have had a hard time finding a Vitamin C product that doesn’t irritate my skin. I have tried many high end products and this is the very best. It is very moisturizing and also has the antioxidant properties. I will continue to use this products.

Alastin C-Radical Defense Antioxident

I’ve been using this for 2 months now. I have really noticed the appearance of my skin has greatly improved! I was skeptical but now I’m a believer in this product. It is pricey. But it is really improving my skins appearance.

Great Vitamin C

I love this Vitamin C. It’s creamy and goes on so smooth. I have sensitive skin and have tried others with no success. It be pricey, but well worth it.

The Only Vitamin C I Use

I have tried so many vitamin C products over the past 10 years. I actually quit and started up so many times because they would either cause breakouts or extreme irritation. I received a sample of this one, of course gave it a shot, and had no issues. I am on my fourth tube and I am DELIGHTED to finally have a vitamin C that works for me.

Good but pricey

I like the pump and the ease of spread, but it is expensive for a serum that needs to be replaced somewhat often. No issues, but haven't noticed a dramatic difference from another high-end brand medical grade that used a dropper bottle. Will keep using for now, but might alternate between the two. This bottle will travel much better.

Alastin C-Radical

This is the best Vitamin C I have ever used thus far. Not greasy, very smooth texture, and most of all did not irritate my sensitive skin. It's worth the price.

My favorite Vitamin C Serum

I really like this Alastin C-Radical Serum, it applies easily and doesn't feel sticky. I use it every day after washing my face, before applying my moisturizer and makeup. I just wish it wasn't so expensive.

Great Vitamin C product.

I alternate using this product with SkinCeuticals Silymarin. Both are effective.

Worth the price!

Yes, it is expensive, but the products are incredible. I especially love the C serum, it keeps my skin looking great! So while it may seem expensive, it is definitely worth it!

Giving this a try because I love other Alastin Prodoucts

I have used Skinceutical Vitamin C for many years and thought that I would give a new product a try. So far, I really like it. Like all of the other Alastin products, this is easily absorbed, light weight, and non burning/stinging. Will update after bottle is finished to compare the two products.

Best Vitamin C serum ever!

I've used this product ever since it was introduced several years ago. It's light, not oily or greasy, and absorbs instantly with no tacky feeling after use. I've previously purchased Alastin products directly from the company but I was so excited when LovelySkin became a sales partner. I'll be buying from here from now on.
