Preparing the Skin
1. Assess the Skin
Confirm the treatment area and screen for contraindications: cold sores, active inflammation or pustules, broken skin, retinoid use, and recent peels or cosmetic treatments. Postpone the treatment if contraindications are present.
Prepare a clean, sanitary workstation and put on disposable nitrile gloves.
2. Cleanse
Apply the cleanser to a cotton pad and gently remove oil and impurities.
If the client is wearing makeup, cleanse twice: first remove the makeup, then cleanse again using a fresh cotton pad and more product.
Do not rinse. Pat the skin dry.

3. Prep
Apply a small amount of powder to the treatment area to absorb excess moisture.

The Sugaring Technique
4. Sugar
Choose a paste consistency suited to your working conditions, such as Premium Prebiotic 03N° or 04N°, designed for small areas. Preheat the paste as needed and check its temperature before application.
Use a gloved finger or fingers, or a spatula. A spatula is recommended for eyebrow shaping because it allows more precise placement and control. It can also be used on the upper lip. The finger technique remains an option for both areas.
- Work in small sections, checking the direction of hair growth.
- Apply the paste against hair growth.
- With your free hand, hold the skin taut in the opposite direction of removal.
- Remove the paste with hair growth, using a quick, controlled flick parallel to the skin.

Instead of the balm: when the skin feels uncomfortable, hot, tight or tingly
Soothing R3 Oil
Sichuan pepper extract interacts with sensory receptors to help reduce these sensations. The oil also soothes the skin and helps retain moisture.
