Description
An advanced-strength retinol serum powered by intelligent time-release technology and a bio-inspired botanical complex that boosts the effects of retinol, targeting deeper lines, loss of firmness, and uneven tone for a smoother, more radiant complexion with optimal skin tolerance.
IntelliRET™ 0.5+ is a high-performance retinol serum for established retinol users ready to step up their results. With 0.5% retinol, it targets deeper fine lines and wrinkles, loss of firmness, blemishes, uneven tone, and texture. The same innovative bio-inspired botanical complex found in IntelliRET™ 0.3+ enhances the efficacy of retinol and improves skin tolerance, helping you progress your retinol routine without the disruption traditionally associated with higher strengths.
At the core of its delivery system is cutting-edge microencapsulated retinol, which allows for a gradual, timed-release overnight, maximising efficacy while minimising irritation. The formula is further enriched with soothing and hydrating ingredients like niacinamide and sodium hyaluronate for visible results, delivered in comfort.
IntelliRET™ 0.5+ is part of AlumierMD’s Core 4 Essentials, designed to target visible signs of ageing driven by Oxidative Ageing™ and support long-term skin resilience as part of a complete daily defence approach.
Contains Vitamin A. Consider your daily intake before use.
Key Benefits

- Bio-inspired botanical booster (Chlorella vulgaris) amplifies visible results and supports a more balanced skin response at higher retinol concentration.
- Microencapsulated retinol for controlled, gradual delivery, maintaining performance gains while reducing the barrier disruption typically associated with stronger retinol.

- MATRIXYL® Synthe'6® visibly supports skin structure and firmness, complementing retinol's smoothing effects.
- Helps reduce the appearance of uneven tone and dark spots with continued use.

Ingredients
Microencapsulated Retinol (0.5%): A vitamin A derivative and antioxidant that reduces the look of fine lines and wrinkles and improves texture and tone by strengthening skin, and increasing skin turnover. Retinol exfoliates to help decongest pores and reduce the look of discolouration, making it suitable for blemish-prone skin. Encapsulated retinol allows for a slow release into the skin overnight, minimising side effects, so you can enjoy all the benefits of retinol with little to no irritation.
Niacinamide (vitamin B3): Along with keeping in moisture and boosting hydration, it also increases tolerance to topical retinoids.
MATRIXYL® Synthe'6®: Derived from a peptide naturally found in collagen and laminins, this visibly supports skin structure and targets the look of stubborn wrinkles and skin firmness.
Tetrapeptide-14, Green Tea Extract, Boswellia Serrata Gum: A peptide combined with the antioxidant properties of green tea and the soothing qualities of boswellia.
Sodium Hyaluronate: A salt form of hyaluronic acid that hydrates by drawing water into the outer layers from within the skin. It holds up to 1,000 times its weight in water, making skin appear plumper, softer and smoother.
Full Ingredient List: WATER/AQUA/EAU, GLYCERIN, PROPANEDIOL, DIMETHICONE, CAPRYLIC/CAPRIC TRIGLYCERIDE, ISOSTEARYL ALCOHOL, HYDROXYETHYL ACRYLATE/SODIUM ACRYLOYLDIMETHYL TAURATE COPOLYMER, NIACINAMIDE, RETINOL, BOSWELLIA SERRATA GUM, CAMELLIA SINENSIS LEAF EXTRACT, ALOE BARBADENSIS LEAF JUICE, CHLORELLA VULGARIS EXTRACT, TETRAPEPTIDE-14, PALMITOYL TRIPEPTIDE-38, HYDROXYPROPYL CYCLODEXTRIN, SODIUM HYALURONATE, HYDROLYZED HYALURONIC ACID, LECITHIN, AMMONIUM ACRYLOYLDIMETHYLTAURATE/VP COPOLYMER, GLUCONOLACTONE, POLYSILICONE-11, POLYURETHANE CROSSPOLYMER-1, BUTYLENE GLYCOL, XANTHAN GUM, TOCOPHEROL, SORBITAN ISOSTEARATE, METHYLPROPANEDIOL, POLYVINYL ALCOHOL, CAPRYLYL GLYCOL, CALCIUM GLUCONATE, HYDROXYACETOPHENONE, DECYL GLUCOSIDE, PHENYLPROPANOL, LACTIC ACID, CITRIC ACID, DISODIUM EDTA, SODIUM HYDROXIDE, SODIUM BENZOATE, 1,2-HEXANEDIOL.
Backed by Science
Achieving stronger retinol results has traditionally meant accepting greater skin disruption. This trade-off exists because higher retinol concentrations increase the rate and intensity of skin cell turnover, but without adequate barrier support this acceleration can outpace the skin's ability to maintain comfort and integrity.
IntelliRET™ 0.5+ is engineered to decouple retinol strength from retinol disruption. The microencapsulation system controls the delivery rate of retinol at 0.5% concentration, reducing the irritation peak without reducing efficacy. The bio-inspired botanical booster (Chlorella vulgaris) works in synergy to amplify the visible renewal response while actively supporting a more balanced skin reaction, helping the skin better adapt to the higher concentration over time.
At this strength, users can expect more visible improvements in fine lines, skin texture, firmness, and uneven tone compared to 0.3+. The supporting ingredient system of Niacinamide, Matrixyl® Synthe'6™, the calming complex, and Sodium Hyaluronate is designed to maintain the barrier and comfort conditions needed to sustain those results over the long term. This is advanced retinol performance, made sustainable.

Who is IntelliRET™ 0.5+ recommended for?
IntelliRET™ 0.5+ is recommended for established retinol users who have completed a period of consistent use at 0.3+ and are ready to advance under professional guidance. It is appropriate for addressing more advanced visible signs of ageing, skin texture irregularities, uneven tone, and blemish-prone skin. It is not suitable for those with rosacea, highly reactive skin, or barrier-impaired skin at this concentration.
What results can I expect at 0.5+ compared to 0.3+?
At 0.5%, users typically experience more visible improvements in the appearance of fine lines, skin texture, firmness, and tone, delivered more quickly than at 0.3+. The IntelliRET™ system is designed to deliver these gains while supporting the barrier comfort needed for consistent use. Individual results will vary and are best supported by regular professional review.
Is IntelliRET™ 0.5+ suitable for blemish-prone skin?
Yes. IntelliRET™ 0.5+ is appropriate for blemish-prone skin under professional guidance. Retinol at this strength supports visible improvement in skin texture and pore appearance. The IntelliRET™ system's barrier-supporting ingredients help manage the increased sensitivity that can accompany retinol use in blemish-prone skin. Not suitable for active rosacea.
How should I transition from 0.3+ to 0.5+?
The transition from IntelliRET™ 0.3+ to 0.5+ should be made under the guidance of your skincare professional. Begin with two to three applications per week at 0.5+ and increase frequency gradually as tolerated, mirroring the introductory approach used when starting 0.3+. Ensure your skin barrier is stable before beginning the transition, and do not attempt to accelerate the progression without professional guidance.
