Can any pharmacy in Ontario make a custom cosmetic cream?

No, not all pharmacies in Ontario are equipped to create custom cosmetic products. Compounding pharmacies are specially licensed to make personalized formulations, including custom skincare. These pharmacies have the expertise and facilities to safely mix and prepare creams with specific ingredients, concentrations, and bases.

## Miscellaneous Questions

What goes into a custom cosmetic cream?

Custom creams typically include: * **Active Ingredients**: These are the components that address specific concerns, like retinoids for fine lines, vitamin C for brightness, or salicylic acid for acne. * **Bases**: The base is the cream’s main structure, affecting texture, absorption, and feel on your skin. Depending on your skin type, you can choose from lightweight gels, rich moisturizers, or other options tailored to your needs. A skin specialist or compounding pharmacist will work with you to select the ideal ingredients and base to match your skincare goals.
