Obagi Nu-Derm Fx explained: the non-prescription system for uneven skin tone

Written by Dr Elif Benar, dermatologist at Dr Elif Clinic, 54 Harley Street, London. Our doctors use and recommend these products in clinic every day.

Obagi Nu-Derm is best known as a skin transformation system. The Fx version is the non-prescription range, designed to improve the look of uneven tone, dark spots and sun damage without a prescription.

The products in the Fx range

• Cleanser and toner: Foaming Gel or Gentle Cleanser, then Toner.
• Clear Fx: a brightening cream with arbutin to help even out the look of dark spots.
• Exfoderm (normal to dry skin) or Exfoderm Forte (normal to oily skin): gentle exfoliation to smooth texture.
• Blend Fx: an evening brightening and blending cream.
• Sunscreen: essential. Pigmentation returns quickly without daily SPF.

The full set is available as the Nu-Derm Fx System for normal to oily skin and the Nu-Derm Fx System for normal to dry skin.

What to expect

Pigmentation improves slowly. Most people see a change after 8–12 weeks of consistent use with daily SPF. Some redness, dryness or flaking can happen in the first weeks as the skin adjusts.

When to see a doctor

Melasma and stubborn pigmentation often need a tailored plan. Stronger prescription treatments exist, but they are only available after a consultation with a doctor who has assessed your skin. A new or changing dark spot should always be checked by a doctor.

Frequently asked questions

Can I use only some of the products?

Yes. Many people use Clear Fx with their own cleanser, moisturiser and SPF.

Can I use Nu-Derm Fx with vitamin C?

Yes, vitamin C in the morning works well alongside the system.
