    Protocol: Average results shown. A 12-week, single-center, clinical study was conducted on 50 females, ages 25 to 60, Fitzpatrick I-IV, with mild to moderate facial skin discoloration, including stubborn dark spots, post-acne marks, and uneven skin tone. Discoloration Defense was applied to the face twice a day in conjunction with a sunscreen. Efficacy and tolerability evaluations were conducted at baseline and at weeks 2, 4, 8, and 12.

  • Science & Proof

  • Science

    Everyday elements—including UV exposure, prescription drugs, and some professional treatments—can trigger production of melanin in the skin’s lowest epidermal layers. This excess melanin rises to the surface of the skin, causing visible skin discoloration. Discoloration can manifest in a range of ways, including post-acne marks and stubborn brown patches on the cheekbones, forehead, and upper lip.

    Discoloration Defense is the latest-generation dark spot corrector, using a combination of potent and proven anti-discoloration ingredients—including new tranexamic acid—to address key types of skin discoloration.

Key Ingredients

  • 3% Tranexamic Acid
  • 1% Kojic Acid
  • 5% Niacinamide
  • 5% HEPES

This synthetically-derived ingredient minimizes the reoccurrence of skin discoloration and stubborn brown patches with continued use.

Physician Insight

Physician image

I recommend Discoloration Defense between chemical peels- this formula targets stubborn types of discoloration but is gentle on my patients’ skin, making it ideal for an at-home regimen between treatments.

Rated 1 out of 5 by from HORRIBLE...HORRIBLE PRODUCT I purchase this product a few months ago, I've seen no change in my dark spots. Your better off using Sunday Riley or Murad for dark spot.

Rated 1 out of 5 by from Unfortunately I bought this in June after recommendation from my dermatologist, unfortunately it didn't do what I expected it to. I tried thinking to give it some more time to work in but it didnt help my issue.

Rated 5 out of 5 by from My Husband Noticed I’ve been using Discoloration Defense for over a month, twice a day. My husband came home from a long business trip and he noticed the difference in my skin. I suffer from skin redness and any sun exposure gives me little darkened patches. The Discoloration Defense has greatly reduced my skin’s redness and sun damage. My skin tone is more even and my face is more pale (in a good way-before my face was darker than my neck and it looked funny). I’ll be using this product in my daily regimen for the foreseeable future.

Rated 1 out of 5 by from Just finished my 2nd bottle and NO DIFFERENCE. Really disappointing. I have used this twice a day (I apply it 20 mins after my CE Ferulic serum every day. I wait another 15 minutes and apply my sunscreen. ) Absolutely no detectable decrease in my skin pigmentation which was caused by pregnancy. I have even photographed my skin every few months since first purchasing this to see if there would be any change. There was absolutely no difference.

Rated 1 out of 5 by from Don’t buy this I bought this product from my doctor’s office. I used it on 1 hand for 10 weeks. When I went back for a followup appointment, no one could tell which hand I used it on. The nurses couldn’t tell me which side of my face I had used Phloetin CF either. What a waste of nearly $300! You won’t know if a product is working unless you test it on 1/2 of your body to know if it is helping or not. Save your money.

Rated 1 out of 5 by from Unsure I purchased this product based on a few recommendations including my dermatologist so needless to say I had high hopes. I used the product consistently for a few months and unfortunately, I have noticed little change to my hyperpigmentation and melasma. Also, the appearance of the product/serum has darkened (brownish color) over time so I'm unsure if the efficacy has been compromised.

Rated 5 out of 5 by from My favorite This stuff works miracles! As I am with every Skin Ceuticals products, first day of using it I was complimented. Difference with this one is I noticed the change. My eyes looked better. The entirety of skin on my face was simply healthier looking.

Rated 5 out of 5 by from WOW! I get terrible ingrown from shaving my legs and then I have a terrible nervous habit of picking, which as led to some embarrassing scars on my legs. Many products are not always intended for use for anywhere other than the face. I bought this product to try it out on my legs. While I know that it will not completely get rid of the scaring, I have already noticed that the brown spots have faded significantly. The darker ones will need more work but I am optimistic!
