AlumierMD IntelliRET™ 0.3+ | Retinol Serum Review
The Verdict
IntelliRET™ 0.3+ reads as AlumierMD's answer to retinol hesitancy: a 0.3% encapsulated retinol paired with a botanical booster, niacinamide and MATRIXYL® Synthe'6® aimed at people who want the long-term benefits of retinol without a harsh introduction. It's comfort-led rather than maximum-strength, which fits its positioning for sensitive skin and first-time retinol users. Expect visible benefits to build with consistent, correct use — and always pair it with daily SPF.
AlumierMD IntelliRET™ 0.3+ | Retinol Serum | 30ml
£88.50
AlumierMD IntelliRET™ 0.3+ is a progressive retinol serum built around 0.3% encapsulated retinol, a bio-inspired botanical booster and barrier-supporting actives including niacinamide and MATRIXYL® Synthe'6®. It's positioned as a comfortable entry point for retinol newcomers and a lower-irritation option for sensitive or reactive skin, helping improve the appearance of fine lines, uneven tone and rough texture with consistent evening use.
What is AlumierMD IntelliRET™ 0.3+?
IntelliRET™ 0.3+ is AlumierMD's progressive-strength retinol serum, sitting at the lower end of the brand's Retinol Resurfacing range in terms of percentage. The formula pairs 0.3% encapsulated retinol — a delivery form designed to release gradually rather than all at once — with what AlumierMD describes as a bio-inspired botanical booster intended to support retinoid activity in the skin while the formula works to minimise irritation-prone responses. The serum is a lightweight, fast-absorbing 30ml product designed for evening use as part of a wider routine.
Rather than positioning itself purely on strength, AlumierMD frames IntelliRET™ 0.3+ around tolerance: the brand states it is suitable for all skin types and conditions, including those new to retinol or looking for a more comfortable, progressive approach to retinoid use.
Why encapsulated retinol?
Standard, unencapsulated retinol tends to release its full concentration into the skin as soon as it's applied, which is part of why some people experience redness, flaking or stinging when they start using it. Encapsulation wraps the retinol molecule so it releases more gradually over time, spreading out the delivery rather than front-loading it. AlumierMD leans on this delivery method for IntelliRET™ 0.3+ specifically to support the "progressive" positioning of the product — the idea being that skin can access the benefits of retinol with a gentler onset, rather than needing to build tolerance to a harsher formula first.
This doesn't mean the serum is irritation-proof. Retinol as an ingredient class is still capable of causing dryness, sensitivity or purging in some skin, particularly in the first few weeks of use, and individual response varies. The formulation choices here are about tilting the odds toward comfort, not eliminating the adjustment period altogether.
Key ingredients
| Ingredient | Role in the formula |
|---|---|
| Encapsulated retinol (0.3%) | A time-released form of retinol, AlumierMD's headline active for this serum, formulated to support skin renewal while aiming to reduce the irritation associated with unencapsulated retinol. |
| Bio-inspired botanical booster | Described by AlumierMD as working to optimise retinoid performance alongside the encapsulated retinol. |
| Niacinamide | Included to support barrier comfort, elasticity and the appearance of pores alongside the retinol. |
| MATRIXYL® Synthe'6® | A peptide complex included to help improve the appearance of skin firmness and fine lines over continued use. |
| Sodium hyaluronate | A hydrating humectant included to help offset the dryness that can accompany retinol use. |
AlumierMD's product tags for this listing also flag gluconolactone (a PHA) and glutathione as present in the formula, alongside retinol itself. We haven't been able to cross-check these against a full printed INCI panel — see the data gap note below.
How does it feel on skin?
AlumierMD describes IntelliRET™ 0.3+ as a lightweight, fast-absorbing serum with a smooth, silky texture that glides on without leaving a greasy residue. The formula is designed to leave skin feeling hydrated and comfortable rather than tight, which is the sensation many people associate with stronger, unencapsulated retinol products.
Who is IntelliRET™ 0.3+ suitable for?
- Those new to retinol, or wanting a more progressive introduction to retinoids
- Skin showing early signs of ageing, uneven tone or rough texture
- People concerned about fine lines and loss of firmness
- Sensitive or irritation-prone skin that needs barrier support alongside a retinol
- All skin tones and most skin types, per AlumierMD's own positioning
How it fits into a routine
IntelliRET™ 0.3+ is designed for evening use, applied after cleansing and before a moisturiser to help seal in hydration on top of the serum. As with any retinol, patch testing and a gradual introduction are sensible starting points, and a broad-spectrum SPF the following morning is essential while using any retinoid — retinol increases sun sensitivity and skin can be more reactive to UV during use. AlumierMD hasn't published a specific frequency or build-up schedule for this product in the material we reviewed, so for a precise application protocol it's worth checking the product packaging or asking your Skintique practitioner directly, particularly if you're combining it with other actives such as exfoliating acids or vitamin C.
The serum comes in a 30ml format. AlumierMD hasn't published a specific dispenser type (pump versus dropper) in the material we reviewed for this listing — check your product packaging on arrival, and flag anything that looks different from the online listing to our team.
IntelliRET™ 0.3+ vs the Retinol Resurfacing Serum range
AlumierMD also sells a separate Retinol Resurfacing Serum line in 0.25%, 0.5% and 1.0% strengths, which uses a different formulation approach to IntelliRET™ 0.3+. Broadly, the Resurfacing range is structured around stepping up in retinol percentage as skin builds tolerance, while IntelliRET™ 0.3+ is built around the encapsulated-retinol-plus-botanical-booster approach described above, aimed more squarely at comfort from the outset. Neither is universally "stronger" — they're different routes to the same category of ingredient, and the right one depends on your skin history and what you've used before.
If you're deciding between the two ranges, our Retinol Resurfacing Serum review covers the Resurfacing formula in detail, and our Retinol Resurfacing Serum vs IntelliRET™ 0.3+ comparison sets the two side by side on formulation, tolerance positioning and who each is aimed at.

Frequently asked questions
Is AlumierMD IntelliRET™ 0.3+ a beginner retinol?
AlumierMD positions it as suitable for those new to retinol or looking for a more progressive, tolerance-focused approach, thanks to the encapsulated retinol and supporting botanical booster. Whether it's the right starting strength for you specifically is worth discussing with a Skintique practitioner.
Can I use IntelliRET™ 0.3+ with other actives?
AlumierMD hasn't published specific product-pairing guidance for IntelliRET™ 0.3+ in the material we reviewed. As a general rule, retinol is usually introduced gradually and kept separate from other strong actives like exfoliating acids on the same night — ask our team for a routine tailored to your skin.
Does IntelliRET™ 0.3+ replace the Retinol Resurfacing Serum?
They're two separate AlumierMD ranges rather than a straightforward upgrade path. See our comparison page for how the formulations and positioning differ.
Is IntelliRET™ 0.3+ safe to use during pregnancy?
If you're pregnant or breastfeeding, please contact our team for advice before use.
