Best Alastin Products for Before and After a Procedure
Alastin doesn't make one "post-procedure product" — it makes three, and they're not interchangeable. INhance Post-Injection Serum® (£55/10ml) is built specifically for the area treated with a dermal filler or other injectable. Regenerating Skin Nectar® (£180/29.6ml) is the broader pre- and post-procedure serum, used around laser, peel, microneedling or injectable treatments. HA IMMERSE Serum™ (£100/30ml) is a hydrating add-on with its own 48-hour post-procedure frequency guidance. This guide separates the three so you can check what your practitioner actually recommended, rather than guessing from the name.
Nothing here overrides your own practitioner's aftercare instructions. Where Alastin's own product directions mention timing after a specific treatment, we've quoted them — but if your clinic gave you a different protocol, follow that instead.
Alastin's procedure-adjacent products at a glance
| Product | Built for | Format | Price |
|---|---|---|---|
| INhance Post-Injection Serum® | The area treated with filler or another injectable, specifically | 10ml, cooling metal applicator tip | £55 |
| Regenerating Skin Nectar® | A broader range of procedures — laser, peel, microneedling, injectables | 29.6ml, silicone-based serum | £180 |
| HA IMMERSE Serum™ | Hydration, used alongside either of the above with its own 48-hour guidance | 30ml, lightweight hyaluronic acid serum | £100 |
1. INhance Post-Injection Serum® — for after fillers and injectables, specifically
INhance is formulated for one job: the skin around a dermal filler or other injectable treatment, used as a short, intensive course rather than an ongoing daily serum. It comes with a cooling metal applicator tip, which Alastin positions as comfortable for use on delicate areas including around the eyes and lips, and the key actives are Tripeptide-1 and Arnica, alongside Sodium Hyaluronate Crosspolymer and Acetyl Hexapeptide-38. Alastin's directions call for applying it around four times a day until the 10ml tube is finished — roughly a ten-day course — starting immediately after treatment.
Alastin references clinical studies for this formulation published in the peer-reviewed Journal of Drugs in Dermatology; we're naming the journal because Alastin does, not because Skintique has independently verified the findings.
Skip this one if: your procedure was a laser, peel or microneedling treatment rather than an injectable — INhance's applicator format and four-times-daily protocol are built around the injectable use-case specifically. Regenerating Skin Nectar, below, is Alastin's product for that broader group of procedures.
2. Regenerating Skin Nectar® — the broader pre- and post-procedure serum
Regenerating Skin Nectar is a silicone-based, water-free, preservative-free serum that Alastin positions across a wider range of procedures than INhance — laser, peel, microneedling and injectable treatments all sit within its intended use. The key actives are Arnica, Squalane and Vitamin E, and Alastin's own directions describe applying it after other actives such as retinoids or growth factors, to seal them in rather than as a first step. Some patients also use it as a standalone daily anti-ageing serum once the immediate post-procedure period has passed, per Alastin's own product copy.
Alastin references a published study in the Journal of Cosmetic Dermatology for this formulation — again, naming the source rather than claiming independent verification. On timing, Alastin's own guidance is explicit: "procedure care usage can vary — always use as directed by your healthcare provider." That's the instruction to follow, not a generic wait-time from this page.
Skip this one if: you've had a single filler treatment and were told to use something specifically over the injection area for a short, defined course — INhance is the cheaper, more targeted option for that. Regenerating Skin Nectar is the wider-use serum, and at £180 for 29.6ml it's one of the more expensive products in the range.
Where HA IMMERSE Serum™ fits in — and its 48-hour guidance
HA IMMERSE isn't a rival to either product above — it's a hyaluronic acid hydrating serum (Sodium Hyaluronate) that some patients layer in alongside them, usually as the first step after cleansing. Alastin's own directions give it a specific post-procedure frequency: apply every 2–3 hours for the first 48 hours after a procedure, then settle into the normal twice-daily routine once that window has passed. That 48-hour guidance is worth knowing even if HA IMMERSE isn't the product your practitioner named directly, since it's the clearest timing instruction Alastin publishes anywhere in this part of the range.
Skip this one if: you're looking for the active, TriHex Technology®-based serum your practitioner mentioned — HA IMMERSE is a hydration step, not a substitute for INhance or Regenerating Skin Nectar.
INhance or Regenerating Skin Nectar: which one do you actually need?
- Had a dermal filler or other injectable, and nothing else: INhance Post-Injection Serum, used as the short applicator-tip course over the treated area.
- Had a laser, peel, microneedling, or a combination of procedures: Regenerating Skin Nectar, following your practitioner's own timing.
- Unsure which your practitioner meant: check the format — a small tube with a metal applicator tip is INhance; a pump-dispensed serum is Regenerating Skin Nectar.
- Want extra hydration alongside either: HA IMMERSE Serum, with its 48-hour frequency step above.

Frequently asked questions
What's the difference between Alastin INhance and Regenerating Skin Nectar?
INhance is built for the area treated with a dermal filler or other injectable specifically, applied via a cooling applicator tip around four times a day for roughly a ten-day course. Regenerating Skin Nectar is the broader pre- and post-procedure serum, used around laser, peel, microneedling and injectable treatments, and some patients continue it as a daily anti-ageing serum afterwards. See our full INhance vs Regenerating Skin Nectar comparison for the details.
How soon after a procedure can I use Alastin skincare?
Alastin's own directions for Regenerating Skin Nectar say to always use it as directed by your healthcare provider, and INhance's directions describe starting immediately after treatment. Timing can genuinely vary by procedure and by clinic, so follow your own practitioner's aftercare instructions rather than a generic timeline.
Do I need HA IMMERSE Serum as well as INhance or Regenerating Skin Nectar?
Not necessarily — HA IMMERSE is a hydration add-on, not a replacement. If you do use it after a procedure, Alastin's directions call for applying it every 2–3 hours for the first 48 hours, then reverting to twice daily.
Can I use INhance around my eyes after filler?
Alastin positions INhance's applicator tip as suitable for delicate areas including around the eyes and lips, but always confirm with your own practitioner given the specifics of your treatment.
Is Regenerating Skin Nectar the same product as INhance, just bigger?
No — they're formulated differently for different use-cases, not the same serum in different sizes. Regenerating Skin Nectar is silicone-based and water-free with a pump dispenser; INhance uses a metal applicator tip and a different core active complex (Tripeptide-1 and Arnica versus Regenerating Skin Nectar's Arnica, Squalane and Vitamin E).
