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.

Alastin C

Tried others and this was is the winner. I am finding Alastin products to be a nice choice for me. A bit more expensive but worth it

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.

Non-sticky

The first non-sticky vitamin c that I’ve found. Lightweight and soaks right in.

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.

Favorite Vitamin C Serum

This is my go-to vitamin C serum. Not sticky, lightweight and works in conjunction with the other Alastin products I use.

Love the line

This is the best C serum I’ve ever used. I love the whole line and my skin looks great since I’ve been using the products. One pump is all that’s needed. Soaks right in and no sticky feeling afterward.

Not my favorite

Not my favorite product but did its job. After a four month bout of facial dermatitis during which I stopped all serums, my usual Vitamin C product was going to be too irritating. I introduced this product without any irritation, redness or inflammation. After using it for two months, some of the new fine lines which developed during my dermatitis have improved. This product will not leak when traveling but it is a large container. There is no fragrance of any kind. It does require about 60 seconds to "dry" on the skin. Won't be buying it again.

So far so good

I haven’t used this but about a week but so far it has brightened my skin and seems to even out my tone. I will leave a more in depth review later.
