CLAIM TO FAME: A transparent masque for efficient, yet innocuous, cleaning and visible refinement of pores

FAST FACTS: Results in an immediate and maintainable visible reduction in both the number and the size of pores due to aging and environmental exposure; works to restore the appearance of pores to an ideal state, within individual genetic limits; makes use of a highly-densified sap from Greek mastic trees that binds to congestion like gum would; this sap used is powerfully anti-bacterial and anti-fungal and is sustainably sourced and purified in a very precise bio-technology lab with extremely high purity; features a pH level of 6.00 to 7.00; formulated without oil and silicone; cruelty-free

PERFECT FOR: Purifying and shrinking the look of pores without drying skin

“(White, just 40, sensitive w rosacea)”
“I love this product. I use it in conjunction with the ordinary 5% retinol - retinol at night and MM in the morning - and together, I have noticed a visible improvement in my pore size. But the best part is that it reduces redness for me and makes my skin feel smooth. After using this product, I can use a lighter foundation. For me, this product is not drying. Will definitely repurchase.”

The formulations are updated from time to time as part of NIOD’s commitment to innovation. As such, the ingredient list shown here may vary from the box of the product depending on time and region of purchase.

Apply a generous amount of this translucent masque to clean face in the AM. Leave on for 10 minutes. Rinse thoroughly with warm water. Do not use a cleaner after rinsing. This formulation uses highly-concentrated mastic gum to bind to impurities, resulting in a sticky feel during the treatment period. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Refer to our in-depth guide to patch testing. Keep out of reach of children.

Note: After rinsing thoroughly, an unessential but beneficial step is to use a blowdryer on a tolerable heat setting for about 15 seconds to dry the face. This step would enhance the visible results of MM immediately.

Note: It is not possible to modify the genetically-determined number or size of pores as apparent in optimal skin condition. However, pores do become more apparent in number and size with ageing and environmental exposure. MM works to restore the appearance of pores to an ideal state, within individual genetic limits.
