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, maximizing efficacy while minimizing 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 aging driven by Oxidative Aging™ and support long-term skin resilience as part of a complete daily defense approach.

Contains Vitamin A. Consider your daily intake before use.

Key Benefits
  • Higher-strength retinol performance that targets the appearance of deeper fine lines, loss of firmness, uneven tone, and skin texture irregularities with greater intensity than 0.3+.
  • 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.
  • Niacinamide reinforces barrier integrity and supports moisture retention for comfortable, consistent use.
  • 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.
  • Part of the IntelliRET™ progressive strength pathway: step two between 0.3+ and 1.0+.
  • Precision-dose needlenose tube for controlled, hygienic application. For use under professional guidance.

Directions

Apply a pea sized amount to face after cleansing at night. Follow with your favorite AlumierMD moisturizer. Recommended once your skin is comfortable with nightly use of IntelliRET™ 0.3+ or another retinol. Begin using two to three times a week and gradually increase frequency to nightly as your skin adjusts, as directed by your skincare professional. Not recommended for rosacea or highly reactive skin.

Cautions: For external use only. Avoid contact with eyes, eyelids, and mucous membranes. Keep out of reach of children. Use only as directed. If irritation occurs or persists, discontinue use and consult a physician. Do not use if you are pregnant, lactating or planning to become pregnant.

Contains Vitamin A. Consider your daily intake before use.

Sunburn Alert: This product contains retinol that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn. Use sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.


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 discoloration, making it suitable for blemish-prone skin. Encapsulated retinol allows for a slow release into the skin overnight minimizing 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.

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.

Questions, answered

Still unsure what fits your routine?

Ask your AlumierMD skincare professional

What retinol strength should I start with for treating hyperpigmentation?

For those beginning a retinol regimen, AlumierMD's 0.25% Retinol Resurfacing Serum is typically the recommended starting point. Starting at a lower concentration allows the skin to build tolerance gradually before progressing to 0.5% and ultimately 1.0% under professional guidance. The microencapsulated delivery system in all three strengths significantly reduces the initial irritation that causes many new users to discontinue retinol before results are achieved, making consistent use, and the improvements it produces, far more achievable.

How does microencapsulated retinol work differently from conventional retinol?

Conventional retinol is applied to the skin's surface in its active form, which can cause significant irritation and barrier disruption before the skin adapts. Microencapsulated retinol is encased in a polymer shell that releases the active ingredient gradually as it is absorbed into the skin, producing comparable cell turnover and pigmentation results over time while minimizing the redness, peeling, and sensitivity that lead many to abandon conventional retinol prematurely. All AlumierMD retinol formulations use this microencapsulated delivery system.

Can retinol treat post-inflammatory hyperpigmentation from acne?

Yes. Retinol is clinically effective for post-inflammatory hyperpigmentation because its cell turnover acceleration lifts pigmented cells to the surface and replaces them with more evenly pigmented new cells. For concurrent active breakouts, the Bright & Clear Solution provides targeted Salicylic Acid exfoliation to manage the blemish-prone environment while the retinol addresses residual pigmentation. A professional consultation is recommended to ensure both are introduced safely and at the correct cadence.

How do I use retinol alongside other active ingredients?

Retinol is typically applied at night, where it works without UV interference. In the morning, EverActive C&E® + Peptide provides antioxidant protection to shield against the UV-generated oxidative damage that triggers new pigment formation, complementing the cell turnover work of the evening retinol. A certified AlumierMD professional will sequence and dose your regimen precisely to maximize results while maintaining tolerability.

How do I order AlumierMD products?

To order AlumierMD products, you must link your account to one of our certified clinics during checkout.
