Walk into pretty much any dermatologist’s office or med spa, and you’ll see SkinMedica and Alastin sitting right there on the shelf. Both cost a lot more than what you’d grab at the drugstore, and both have loyal fans who swear by them. So when it comes to SkinMedica vs Alastin, which one is actually worth your money?
I spent some time digging into both brands. Here’s what I learned.
A quick look at both brands
SkinMedica has been around since 1999, which makes it kind of the old reliable of medical-grade skincare. It’s owned by Allergan (the same company that makes Botox), and dermatologists have been recommending it for over twenty years. The brand is known for its science-heavy approach, and a lot of people credit it with starting the whole “growth factor” trend in serums.
Alastin is the newer kid on the block. It launched in 2015, but it grew fast. The brand was started by a team that included a plastic surgeon, and it focuses on something they call TriHex Technology. That’s a fancy name for ingredients that supposedly help your skin clear out old, damaged stuff and make new collagen and elastin. Both brands are sold mostly through skin doctors and clinics, not at Sephora or Target.
Price: which one costs more?
Honestly, both brands will hurt your wallet a little. Neither is cheap. But there are some real differences once you start comparing specific products.
SkinMedica tends to land in the $50 to $300 range for most items. Their famous TNS Advanced+ Serum runs about $295 for one bottle, which is the splurge product everyone talks about. Cleansers and basic moisturizers are more affordable, sitting around $50 to $80. You can also find SkinMedica on sale sometimes, especially through medical spas that run promotions.
Alastin is also pricey, but slightly more consistent across the board. Most products fall between $55 and $220. Their Restorative Skin Complex, which is one of their best sellers, costs around $258. Alastin doesn’t usually go on big sales, but the brand does offer kits that bundle products together for a small discount. If you’re shopping by price alone, SkinMedica has cheaper basic items, but its hero serum is more expensive than anything Alastin sells.
Texture: how do they feel on your skin?
This is where personal preference really matters. The texture of a product can make or break whether you actually use it every day.
SkinMedica products tend to feel a little richer and heavier. Their serums are often thicker, almost like a light lotion, and they take a moment to soak in. Some people love this because it feels luxurious and moisturizing. Others find it a bit much, especially in summer or if they have oily skin. The TNS Advanced+ Serum, for example, has a noticeable scent that some people compare to a vitamin smell. You either don’t mind it or you really do.
Alastin feels lighter and more modern. Their serums absorb fast and don’t leave any sticky film behind. The Restorative Skin Complex goes on almost like water and disappears into your skin within seconds. There’s barely any scent, which is great if you have sensitive skin or just don’t like fragrance. People with combination or oily skin often prefer Alastin because nothing feels heavy. If you wear makeup, Alastin tends to layer better under foundation without pilling.
Top product from SkinMedica
If you’re going to try only one thing from SkinMedica, make it the TNS Advanced+ Serum. This is the product that built the brand’s reputation, and there’s a reason it keeps selling out at clinics. It uses growth factors and peptides that target fine lines, sagging, and overall skin tone.
People in their 40s and 50s tend to see the biggest improvements, but younger users have reported smoother texture too. You apply it twice a day, and most users say they notice a difference around the eight-week mark. It’s not a quick fix. The downside? The price is steep, and that vitamin-like smell isn’t for everyone. But if you have the budget and want something with a long track record, this serum delivers. A lot of dermatologists keep using it on their own face, which says something.
Top product from Alastin
For Alastin, the standout is the Restorative Skin Complex. This is the product Alastin built its name on, and it’s the one most people start with. It uses TriHex Technology along with niacinamide, vitamin E, and a bunch of peptides to support collagen and elastin in your skin.
What sets it apart is how it feels and how fast you see results. Many users report softer, plumper skin within a few weeks, and the lightweight texture means people actually stick with it. It’s a great pick if you’ve had treatments like microneedling, lasers, or chemical peels, because Alastin originally designed its products to help skin recover after those procedures. The price sits around $200, which isn’t cheap, but it’s lower than SkinMedica’s top serum and you get a product that works for almost every skin type.
So which brand is the best?
Here’s where I’m going to be honest with you: there isn’t one right answer for everyone. But if I had to pick, I’d lean Alastin for most people.
Here’s why. Alastin gives you a more modern formula at a slightly lower price point, and the lightweight feel means you’re more likely to actually use it every day. Skincare only works if you stick with it, and a product that feels good is a product you’ll keep reaching for. Alastin also tends to play well with other treatments, so if you’re someone who gets facials or in-office procedures, the brand fits naturally into that routine.
That said, SkinMedica wins in two specific situations. If you have dry or mature skin and want something rich and proven, SkinMedica is hard to beat. The TNS Advanced+ Serum has decades of dermatologist trust behind it, and the brand’s basic items like cleansers and moisturizers are affordable enough to build a full routine around. Older skin often responds better to richer textures, and SkinMedica delivers there.
The truth is, both brands work. Neither is a scam, neither is a waste of money. Your skin type, your age, and what you’re trying to fix should drive the choice more than brand loyalty. If you have oily or combo skin and you want results without a heavy feel, go Alastin. If you have dry, mature skin and you want something with a long history, go SkinMedica. And if you can swing a consultation with a dermatologist, that’s still the best way to figure out what your specific skin actually needs. Either way, you’re not making a bad choice with these two.
