FAQ

Frequently asked

Common questions about booking, treatment, price, pain, and downtime.

Sapphire contact cooling chills the skin surface throughout the treatment, keeping irritation and pain low, so it's usually done without anesthesia. Depending on the lesion area or number, topical anesthesia may be used when needed.

A thin crust forms over treated spots and falls off naturally in about a week. Avoid picking it and keep up moisturizing and sun protection for clean recovery without pigmentation.

Epidermal pigment removal targets defined lesions. Diffuse melasma or dull tone is better addressed with laser toning or pico treatments; we'll guide a tailored combination after diagnosis.

It treats epidermal pigment lesions with clear borders—such as lentigines, seborrheic keratoses, freckles, and spots—selecting the device best suited to each lesion for precise removal.

It depends on the lesion type and depth, but well-defined lentigines and seborrheic keratoses often improve markedly in 1–2 sessions. Any further treatment is decided after the crust falls off.

A thin crust forms over the treated spots and naturally falls off in about a week. During this time, avoid picking it and focus on moisturizing and sun protection for clean recovery without pigmentation.

Because only the superficial epidermal pigment is targeted and contact cooling protects the surrounding skin, the spot usually heals without a scar once the crust falls off. Keeping up sun protection and moisturizing afterward ensures clean recovery without temporary pigmentation.
