Introducing Hydroxysomes®

An Innovative Patented Dermal Delivery Platform

exceeding metrics of other dermal delivery technologies






Why Hydroxysomes®

Issued Hydroxysome® patents on core technology and applications provide a unique and defensible competitive advantage


88% of all API drugs and consumer bio-actives currently do not have any dermal delivery options other than Hydroxysomes® due to incompatible chemistries, molecular weight limitations, or instability issues

Issued Hydroxysome® patents on core technology and applications provide a unique and defensible competitive advantage.



Limitations of Other Dermal Delivery Technologies:

 Formulation Based:

Add active to cream, ointment or gel and apply: “spray and pray”

Leads to lack of efficacy, poor compliance, irritation potential, high dose frequency


Patches; Liposomes; Encapsulation; Devices, and others:

Damaging – Adhesive can irritate skin; often use penetration enhancers

Limiting – Potent drugs with low daily dosage; may have formulation challenges

Inefficient – Small % delivered; excessive loss of  API/Active



How Hydroxysomes® Work:


Hydroxysomes® is co-engineered with active and formulated into conventional topical products, e.g. creams, ointments, lotions.

Upon application, it functions in essence as a “patchless patch” to implement and facilitate enhanced uptake by the skin, and to release high yield active.


Sustained Release Skin Delivery:

Hydroxysomes® are not stable at pH below 5: release of API Active is controlled by stratum corneum acidic pH.

Active continues to pass through to the lower epidermis, and/or dermis, and/or systemic flow-through, depending on the characteristics of the active.

Hydroxysomes® particles remain localized in stratum corneum; calcium and
phosphates ions of Hydroxysomes® are slowly absorbed as micronutrients by the skin.

with no calcium in SC
           After application,
calcium can be seen in SC
    7 hours after application,
calcium continues to be absorbed
