Do Products Like Spectro Gel Really Cure Acne?

By Dr. Jaggi Rao, MD, FRCPC, Double board-certified dermatologist

Spectro makes skin care products for acne and eczema. Its acne products offer the proven power of benzoyl peroxide, in mild concentrations for sensitive skin.

Spectro Jel, which is actually a light lotion, is good for treating back acne.


  • Spectro is a division of Glaxo Smith Kline that makes benzoyl peroxide lotions and pads for acne treatment in Canada.
  • Spectro actually does not make a “gel.” Its products are a light lotion for use once or twice a day on a regular basis.
  • The 2.5% concentration of benzoyl peroxide in Spectro Vanishing Lotion for Sensitive Skin is a good place to start treating acne.
  • Use the 5% benzoyl peroxide Deep Pore Vanishing Lotion when you know you do not have any adverse reactions to benzoyl peroxide.
  • If you know you have sensitive skin (you have allergies or eczema, or certain chemicals make you break out), use Spectro’s Cleansing Pads for Sensitive Skin.
  • Spectro is an especially good treatment for back acne.
  • Use sunscreen if you use the product and you might be exposed to strong summer sun.
  • For a more complete acne care solution, consider Exposed Skin Care.

Spectro Products for Acne

Spectro makes three different products for acne care. Its Vanishing Lotion for Sensitive Skin is a 2.5% concentration of benzoyl peroxide in a light lotion that sticks to the skin without feeling greasy. Its Deep Pore Vanishing Lotion is a 5% solution of benzoyl peroxide intended for normal or oily skin in people who are not sensitive to benzoyl peroxide. Spectro Cleansing Pads for Sensitive Skin let the user determine how much benzoyl peroxide to put on the face and for how long, giving complete control over redness and irritation.

Spectro also makes cleansers and moisturizers for blemish-prone, dry, and combination skin. These Glaxo Smith Kline products are sold in Canada only.

Lotion or Pads?

The advantage of Spectro products is that you can choose the strength of benzoyl peroxide you put on your skin. Doctors usually prescribe 5% or 10% benzoyl peroxide products. Many users find them to be simply too strong. Benzoyl peroxide at these concentrations often causes redness, irritation, itching, and sensitivity to the sun, and the hydrogen peroxide released by the product can bleach both clothes and hair.

For people who have sensitive skin, Spectro offers a 2.5% lotion. Light on the skin, this concentration of benzoyl peroxide is usually tolerable. And because it does not cause side effects, people stick to their treatment programs so acne does not come back.

For people who know they can tolerate benzoyl peroxide, Spectro offers a stronger lotion that gets rid of acne bacteria fast. And for people who aren’t sure, Spectro offers benzoyl peroxide pads you can use as gently as you like.

An Excellent Product for Canadian Users

Benzoyl peroxide is not for everyone. If you happen to live in a part of the world that gets lots of harsh, direct summer sun, benzoyl peroxide can make your skin especially sun-sensitive. If you have golden, Asian skin tones, it can even cause pigmentation in the form of persistent brown spots after acne heals.

Harsh summer sun, however, is not a big problem in Canada. Many Canadians can use benzoyl peroxide without side effects, and without irritation. The main consideration for the use of Spectro in Canada is making sure skin does not get overly dry in winter.

When Should Spectro Be Your Treatment of Choice?

The kind of acne that Spectro can treat better than other products is “bacne,” or back acne. Benzoyl peroxide works best on tough skin. The skin on the back is especially tough. Benzoyl peroxide won’t loosen up blackheads on your back, but it is usually the best non-antibiotic treatment for pimples on the back. Use Spectro after your dry off from your bath or shower, but be sure there is a protective barrier between the area of skin your treat on your back and clothes that could be bleached by the product.

Many Canadian doctors prescribe a relatively gentle antibiotic called clindamycin for teens who have acne. If you are using a topical antibiotic gel, alternating with Spectro can kill the bacteria that the antibiotic misses and leave the skin less vulnerable to attack by antibiotic-resistant acne bacteria.

It is important not to use any Spectro acne product more than once a day until you see how it affects your skin. If you don’t have unexpected redness or dryness of the skin, then use the product up to twice a day—less when you are out in the cold or in the sun for an hour or more a day.

Can Spectro “Gel” Cause Anaphylactic Reactions?

If you Google “spectro gel,” one of the first pages you’ll see is the horrifying story of a Canadian nanny who got emergency medical treatment the day after she started using Spectro gel. “Everything was fine the night before,” the anonymous user writes. “I felt it drying out my skin and put on moisturizer. It was great and I was really excited.”

Then the next morning, the testimonial tells us, this user of Spectro gel was late for work. She washed her face, used a dab of Spectro, and noticed some irritation. She thought it was just cold weather dryness, since she lives in Canada. But a few minutes she saw that her whole face was purple. She started coughing. She felt her airways closing up. Her pulse started racing. Had the ambulance not arrived in 5 minutes, she was told, she surely would have died. Now she has to carry an Epi-Pen the rest of her life in case she ever has another equally horrible allergic reaction.

There are a couple of odd things about this report. One is that the first application of the product caused no problems and the second application of the gel allegedly caused an anaphylactic reaction. The other oddity about this report is that HealthCanada keeps track of incidents of this nature and there are no reports of anaphylactic reactions to benzoyl peroxide in Canadian records.

And it’s just a little odd that the Internet story refers to a gel when the product is labeled as a “lotion” in Canada.

Could an equally horrible reaction happen to you? Well, yes. It’s very remotely possible. Many people have serious allergic reactions. Literally hundreds of thousands of substances trigger allergies. But nothing of this severity has happened to anyone else who has used Spectro gel. No such problems, however, have been reported by users of products made by Exposed Skin Care.

I personally have suffered from severe oily skin with mild breakouts (I would not go anywhere without foundation or powder make up on). I started using Spectro Combination Skin no less than 3 weeks ago and I must say I am quite impressed. The first time I used this product I felt a little frightened because I started to severely break out (I don't get pimples often). My whole face was covered I almost thought it was an allergic reaction regardless out of curiosity I continued use. About 2 weeks in I started to notice the acne it had created was clearing up along with my oil, my skin tone has also seen quite a big improvement as well. Now 3 weeks in I feel confident enough to leave my apartment without any foundations or powders I finally feel complete. The product definitely works it just takes time, time well spent! :D
