About this concentrate
APSTEM is the apple-based concentrate used as a foundation in many of the instructor's topical combinations. Its featured ingredient is apple stem cell culture, with water, vegetable glycerin, and hyaluronic acid in the formula.
Choose it for general facial skincare focused on a smooth, supple, well-moisturized appearance. The concentrate can be selected on its own or incorporated into a compatible practitioner-prepared blend. Plant cell culture describes the botanical origin of the featured ingredient.
When to choose it
- A dry-looking or dull-looking complexion
- Fine lines associated with dryness
- General facial skincare with a smooth, supple-looking finish
Preparation & use
Why dilute?
Our serums are supplied in concentrated form. Dilution helps you tailor the strength and texture, make each vial go further, and reduce concentrate costs per application. Use a compatible base and follow the preparation guidance below.
Dilution at a glance
The standard preparation range is 10–20% concentrate in the finished blend. Choose the strength and compatible base for your formulation protocol.
| Final blend | 10 mL batch | Using one 15 mL vial |
|---|---|---|
| 20% concentrate | 2 mL concentrate + 8 mL base | 15 mL concentrate + 60 mL base = 75 mL |
| 10% concentrate | 1 mL concentrate + 9 mL base | 15 mL concentrate + 135 mL base = 150 mL |
These percentages describe the bottled concentrate as a share of the finished blend, not the percentage of pure botanical ingredient.
Base selection: The workshop materials discuss hyaluronic acid, vegetable glycerin, and purified water as blending mediums. Use these only within a compatible, verified cosmetic formulation; the finished blend needs appropriate preservation and stability.
Use the prepared formula on clean skin. When combining concentrates, follow a verified blend rather than adding several full-strength products together.
Prepare with care
- Use clean hands, a sanitized work area, and clean measuring tools and containers. Measure accurately and mix thoroughly.
- Use a compatible cosmetic base and a verified formulation protocol. Adding water or other ingredients changes preservation and stability; a dilution ratio alone does not establish a safe shelf life.
- Keep the original vial tightly closed. Follow its label for storage and expiry. Do not assign the original expiry date to a diluted or blended product without appropriate formulation testing.
Care & precautions
- For external topical use. Do not ingest.
- Patch test the finished formulation on a small area before wider use. Avoid contact with eyes and mucous membranes. Stop use if irritation occurs.
- Use professional judgment when selecting the formulation, application method, and timing for each client.
- Use caution during pregnancy and seek appropriate professional guidance before use. Check the complete ingredient list for known sensitivities.
