Pick SkinMedica TNS Advanced+ ($295) if you want the most-studied growth factor serum and have 40+ skin with visible laxity. Pick Alastin Restorative Skin Complex ($215) if you want TriHex peptide technology, are 30-45 with early aging signs, or recently had an in-office treatment. Both are derm-office staples. TNS wins on data; Alastin wins on price and post-procedure use.
The two serums your derm probably recommends first. Similar price bracket, similar promise, completely different mechanisms. Here’s how to pick.
Quick answer
| Product | Price | Best for | Rating | Where |
|---|---|---|---|---|
| SkinMedica TNS Advanced+ | $295 | Growth factors + peptides. Deep anti-aging for 40+ | 9.5/10 | Buy → |
| Alastin Restorative Skin Complex | $215 | TriHex peptides. Early aging + post-procedure | 9.0/10 | Buy → |
The technology difference
TNS Advanced+ uses growth factors and cytokines (450+ signaling molecules harvested from fibroblasts) to tell skin cells to act younger. Alastin uses TriHex Technology — synthetic peptides designed to clear old elastin and collagen fragments and stimulate production of new, healthy ones. Different goal: TNS signals, Alastin cleans + rebuilds.
SkinMedica TNS Advanced+ (growth factor approach):
- 450+ growth factors, cytokines, and peptides
- Fibroblast-derived signaling molecules
- Targets multiple aging pathways at once
- Works best on already-damaged skin (late intervention)
Alastin Restorative Skin Complex (enzyme + peptide approach):
- TriHex peptides (proprietary tri-peptide + hex-peptide combo)
- Designed to clear degraded elastin/collagen debris
- Stimulates fresh collagen and elastin synthesis
- Works best pre- and post-procedure, or for early aging
Think of TNS as “turning the factory back on” and Alastin as “cleaning out the warehouse and starting a new production line.”
Age and skin profile match
If you’re 40+ with visible laxity, crepiness, or deep lines, TNS Advanced+ is the better match. If you’re 30-45 with early texture changes, post-procedure recovery, or want prevention, Alastin Restorative Skin Complex is the better fit.
Pick TNS Advanced+ if you are:
- 40+ with visible laxity or deep lines
- Plateaued on tretinoin and want the next level
- Done with in-office treatments and maintaining results
- In the “I want the most-studied product” camp
Pick Alastin if you are:
- 30-45 with early aging signs
- Scheduled for (or just had) microneedling, laser, or IPL
- Looking for prevention more than correction
- Sensitive to growth factor ingredients (some people are)
- Budget-conscious within the premium tier ($80 less)
Texture and feel
TNS Advanced+: dual-chamber pump, blends at dispense. Slightly tacky during absorption, smooths out in 2-3 minutes. Vaguely milky appearance.
Alastin Restorative Skin Complex: single-chamber pump, silky feel, absorbs faster. Feels more like a lightweight cream than a serum. No tackiness.
If you’re layer-heavy (serum + moisturizer + oil + SPF), Alastin plays nicer in the stack. TNS needs a 60-90 second wait before the next layer.
Clinical data side-by-side
TNS Advanced+:
- 24-week SkinMedica study, n=55
- Measurable improvement in 8 of 8 wrinkle/laxity endpoints
- 58% saw improvement in neck laxity (hardest-to-treat area)
- Most-published growth factor serum in peer-reviewed literature
Alastin Restorative Skin Complex:
- Multiple studies on TriHex Technology in peer-reviewed journals
- Demonstrated elastin regeneration in ex-vivo skin models
- Strong post-procedure data (significantly improved healing vs control)
- Used in most derm offices as the default pre/post-procedure serum
TNS has more total studies. Alastin has more procedure-specific data. Both are legit; this isn’t a bad science vs good science situation.
The real-world combo question
You can use both — and many derms actually recommend it. Alastin in the morning (cleaner, post-procedure-friendly) and TNS Advanced+ at night (deeper repair). Not cheap (~$500 in serums), but this is the “maximum results” stack. Most people can pick one based on age/use case.
If budget allows, the AM Alastin + PM TNS stack is genuinely powerful. Alastin supports daytime environmental defense while TNS drives nighttime repair. Bottles last ~4 months each.
If budget is tight, pick one:
- Under 40 → Alastin
- Over 40 → TNS

Procedure-specific recommendations
If you’re scheduled for microneedling: Alastin, starting 2 weeks before and continuing 4 weeks after. TriHex was literally designed for this.
If you’re scheduled for IPL or laser resurfacing: Alastin before, TNS starting day 7-10 post-procedure (after barrier heals).
If you’re not doing procedures: Pick based on age/concern match above.

Frequently asked
Can I use TNS and Alastin together on the same day? +
Yes. Alastin AM, TNS PM is the common stack. Don't layer both at the same time in the same routine — they compete for absorption.
Is TNS Advanced+ the same as TNS Recovery Complex? +
No. Recovery Complex ($185) is the original single-chamber formula. Advanced+ ($295) is the dual-chamber upgrade with added peptides. Advanced+ has more data behind it.
Are both pregnancy safe? +
Alastin is generally considered pregnancy-safe. TNS has growth factor content that SkinMedica doesn't formally recommend during pregnancy — check with your OB.
Which lasts longer per bottle? +
TNS Advanced+ at 2 pumps 2x daily lasts ~4 months. Alastin at 1 pump 2x daily lasts ~3 months. Cost per month comes out similar (~$70-75).
Which absorbs better under SPF? +
Alastin — it's faster-absorbing and doesn't interact with SPF. TNS needs a wait before SPF or you risk pilling.
