Frequently Asked Questions (FAQs)
What skin types is the CLEF Copper Peptide Mask suitable for?
This mask is suitable for all skin types, including sensitive, dry, oily, and combination skin. It’s especially helpful for skin that feels tired, inflamed, or in need of a recovery boost.
What does Copper Peptide do for the skin?
Copper Peptide is a powerful skincare ingredient known to:
- collagen and elastin production
- damaged skin
- skin barrier
- reduce redness
- firmness and elasticity
How often should I use the mask?
For best results, we recommend using the mask 1–2 times per week, or anytime your skin feels dry, irritated, or dull. It’s also perfect as a post-treatment recovery mask.
Can I use the mask after a facial or exfoliating treatment?
Yes! The CLEF Copper Peptide Mask is ideal for post-treatment care. It helps to soothe, hydrate, and repair skin after facials, exfoliation, sun exposure, or other procedures that may leave skin temporarily sensitive.
How long should I leave the mask on?
Leave the mask on for 15–20 minutes. After removing it, gently pat in the remaining essence.
Is this mask reusable?
No, the mask is single-use only. Each sheet is infused with a full dose of active ingredients designed for one intensive treatment.
Can I use it with other anti-aging products?
Definitely. This cleanser is a great pre-step to help your skin better absorb serums/essences, moisturisers, and treatments/masks. It’s especially compatible with Clef’s own anti-aging and hydration lines.
Do I need to apply moisturizer after using the mask?
While the mask provides intense hydration, we recommend sealing in the benefits with a light layer of our CLEF Anti-aging moisturiser for the best effect or your usual moisturiser, especially at night.
Is the mask safe for sensitive or acne-prone skin?
Yes. The formula is alcohol-free, fragrance-free, and made with gentle, non-comedogenic ingredients. It’s designed to calm irritation and support the skin’s recovery process.
Can men use this mask too?
Absolutely! The CLEF Copper Peptide Mask is gender-neutral and suitable for anyone looking to boost hydration, repair their skin barrier, and maintain a healthy glow.
