For dermatology and aesthetic prescribers, a single compounded topical can bring together a prescription retinoid and complementary skin-supporting ingredients — tailored to the strength and combination a patient can tolerate. Mixwell Compounding Pharmacy in Chino, CA prepares custom tretinoin, niacinamide, and hyaluronic acid topical formulations pursuant to a valid prescription, in stable anhydrous bases.
🧪 Three Ingredients, One Custom Topical
Each ingredient plays a different role, which is why prescribers sometimes combine them into one preparation rather than layering separate products.
🔬 Tretinoin
Prescription retinoidA topical retinoid FDA-approved in commercial products for acne. Prescribers also use tretinoin in customized strengths and combinations that aren't commercially manufactured.
🟡 Niacinamide
Vitamin B3 derivativeA well-tolerated skin-conditioning ingredient frequently included alongside a retinoid in customized topical formulations.
💧 Hyaluronic Acid
HumectantA humectant that helps a preparation feel hydrating on the skin — often paired with a retinoid for a more comfortable finish.
❓ Why combine these into one compounded preparation?
Combining a prescription retinoid with complementary ingredients in a single topical lets a prescriber specify the exact strengths and pairing a patient needs — for example, a lower retinoid strength for a patient building tolerance, or a combination and base that isn't sold commercially. The prescriber determines the appropriate formulation for each patient.
🧴 Why the Base Matters for Tretinoin
Tretinoin is sensitive to oxidation, so the base isn't a minor detail — it affects how stable the finished preparation is through its beyond-use date. Mixwell formulates these preparations in advanced anhydrous PCCA bases (water activity below 0.6) chosen to support oxidation-prone actives and an elegant feel.
💎 Anhydrous Base Technology
Built for oxidation-prone actives and a refined finish.
🌿 WO6™
An anhydrous, emollient topical base with a smooth, creamy finish — suited to oxidation-prone actives and stored at room temperature when no aqueous ingredients are added.
💧 PermE8™
An anhydrous permeation-enhancing gel (water activity below 0.6) that supports extended default beyond-use dates and multi-active formulations.
⏱️ Extended default BUDs
Low water activity supports prolonged default beyond-use dating for oxidation-prone preparations.
✨ Elegant feel
A silky, non-tacky finish that supports comfortable daily use.
❓ What is an anhydrous base?
An anhydrous base contains little to no water (water activity below 0.6). For actives that are sensitive to oxidation — like tretinoin and vitamin C — an anhydrous base helps protect them and supports a longer default beyond-use date, often allowing room-temperature storage when no aqueous ingredients are added.
📚 The Evidence Base
Topical tretinoin is a well-established retinoid with FDA-approved commercial products for acne, and a substantial dermatology literature. Topical niacinamide has been studied as a skin-conditioning ingredient, and hyaluronic acid is a widely used topical humectant. Evidence for any specific compounded multi-ingredient combination is more limited than for individual FDA-approved products, and outcomes depend on the formulation, the patient, and use as directed.
Mixwell compounds to your prescription. The prescriber determines whether tretinoin, the combination, and the strengths are appropriate for each patient based on individual evaluation.

⚠️ Important regulatory information — please read
This compounded preparation is not an FDA-approved drug product. FDA-approved tretinoin products are available. A compounded combination is prepared pursuant to a valid, patient-specific prescription when a prescriber determines a commercial product doesn't meet a patient's need.
Pregnancy caution: Topical retinoids, including tretinoin, are generally not recommended during pregnancy. Prescribers assess suitability and counsel patients accordingly.
No promise of results. Under federal law, promotion of prescription drugs — including compounded drugs — must be truthful, non-misleading, and accurate. Nothing here is a claim of a specific cosmetic or therapeutic outcome, or that a compounded preparation is safer or more effective than an FDA-approved product.
FDA recommends that patients talk with their healthcare professional about their specific circumstances before taking any medication.

❓ Frequently Asked Questions
Is this compounded skincare FDA-approved?
No. FDA-approved tretinoin products are available. A compounded tretinoin/niacinamide/hyaluronic acid combination is not FDA-approved; it is prepared individually pursuant to a valid prescription when a prescriber determines a commercial product doesn't meet a patient's need.
Why compound instead of using separate products?
Compounding lets the prescriber specify exact strengths and a single combination — for example, a lower retinoid strength for tolerance, or a pairing and base that isn't sold commercially. The prescriber determines the formulation.
Why does the base matter for tretinoin?
Tretinoin is oxidation-sensitive. An anhydrous base such as WO6™ or PermE8™ (water activity below 0.6) helps protect oxidation-prone actives and supports a longer default beyond-use date, often with room-temperature storage when no aqueous ingredients are added.
Can this be used during pregnancy?
Topical retinoids, including tretinoin, are generally not recommended during pregnancy. Talk with your prescriber, who determines whether any preparation is appropriate for your circumstances.
Should I talk to my prescriber first?
Yes. FDA recommends that patients talk with their healthcare professional about their specific circumstances before taking any medication, including compounded preparations. Consistent sun protection is generally recommended with retinoid use.
