Alastin UK: The Complete Brand Guide

Alastin is a US physician-dispensed skincare brand built on patented TriHex Technology, a peptide-led approach that supports the skin's natural renewal of collagen and elastin. It suits anyone wanting smoother, firmer-looking skin, and is especially popular before and after aesthetic procedures.

What Alastin Is and the Science Behind It

Founded in the US and dispensed through clinics and authorised stockists, Alastin sits in the professional-grade skincare category. Its signature is TriHex Technology: a blend of peptides and botanicals designed to support the skin's own clearing of damaged proteins while encouraging the renewal of fresh collagen and elastin.

The thinking is straightforward. As skin ages, or after a procedure such as microneedling, laser or peels, it benefits from support during recovery and renewal. Alastin's formulas aim to work with that process rather than simply sit on the surface. Peptides do much of the heavy lifting here, and if you like to understand the actives, our glossary explains related ingredients such as copper peptides and tripeptide-1. Evidence suggests peptide-based skincare can help improve the appearance of firmness, tone and texture over consistent use.

As an authorised UK stockist, Skintique offers the range with genuine, in-date stock. You can shop the Alastin range in one place.

The Hero Products

• Restorative Skin Complex — the flagship daily TriHex serum, formulated to support renewal and help improve the appearance of overall skin quality.
• Regenerating Skin Nectar — a nourishing formula often used around aesthetic procedures to support the skin during recovery.
• Restorative Neck Complex — targeted care for the neck and décolletage, where skin is thinner and shows ageing early.
• HA IMMERSE Serum — a hyaluronic acid serum designed to support hydration and a plumper, smoother-looking finish.

How to Choose and Where to Start

If you are new to the brand, most people begin with the Restorative Skin Complex as an everyday TriHex serum, then layer in a hydrating step such as the HA IMMERSE Serum. If your main concern is the neck and décolletage, the Restorative Neck Complex is the natural starting point. Planning an in-clinic treatment? The Regenerating Skin Nectar is the formula most associated with pre- and post-procedure support, so it is worth discussing with your practitioner.

How Alastin Fits a Routine

Alastin layers comfortably into a considered morning and evening routine. A simple structure works well: cleanse, apply your TriHex serum, follow with a hydrating serum such as HA IMMERSE, then moisturise. In the morning, always finish with a broad-spectrum SPF, which supports the results of any firming-focused routine.

Introduce one new product at a time so your skin can adjust, and give any peptide routine several weeks of consistent use before judging results. When in doubt, your clinician or our team can help you sequence products sensibly. You can shop the Alastin range whenever you are ready to build your routine.
