Do dermatologists recommend Zo?
ZO has been created and produced by leading Beverly Hills Dermatologist Dr. Zein Obagi and is recommended and used by dermatologists and Skin Experts all over the world. Zo skinhealth is also recognised as the No.1 Physician-dispensed medical skincare brand in Europe.

What are the side effects of using a ZO retinol?
Dryness, redness, flakiness, burning or stinging are all normal, anticipated reactions when starting retinol. With regular product use, skin will acclimate, revealing a smoother, more even-toned and youthful-looking complexion. You can incorporate your retinol with a ZO® functional hydrator to minimize anticipated reactions.
Why does ZO not believe in moisturiser?
Dr Zein Obagi believes that moisturiser affect the skins’ ability to produce natural hydration, which in turn can lead to dryness, dullness and overly sensitive skin. We believe are bodies can create our own natural hydration.
Why should you not use a ZO retinol every day to begin with?
Initially, retinols can irritate the skin, so it’s advised to start slow, once every few days, and then gradually increase to once or twice per day. At first, you might experience redness, itching or burning, but these symptoms go away as your skin gets used to the treatment.
What is skin purging?
Skin purging is a temporary skin reaction that can occur when introducing new skincare products, especially those with active ingredients like retinols or exfoliating acids. It involves a period where the skin pushes impurities (like dead skin cells, excess oil, and clogged pores) to the surface, often resulting in increased breakouts. This is different from a regular breakout because it’s a reaction to an active ingredient that speeds up cell turnover, bringing underlying congestion to the surface.
Can I buy zo skin health online?
The answer is yes, however, ZO Skin Health can only be sold by authorised stockists who have the knowledge and expertise to correctly prescribe your regime. Sellers on eBay, Amazon or other free to buy retailers are unauthorised, and the product is likely counterfeit, expired or contaminated.

Other products in the range may be suitable, but because every individual’s needs are different, we always recommend a consultation before use.
