Compare Benzamycin vs. Renova

Head-to-head comparisons of medication uses, side effects, ratings, and more.

Topical treatment for acne.

Benzamycin (Benzoyl Peroxide / Erythromycin) is a topical combination acne treatment that may work better for people who didn't see an improvement when taking either medicine alone or simply don't want to take pill medication. You need to be careful because it can bleach your hair, clothing and other fabrics. It also needs to be stored in the refrigerator and is only good for three months..

Treats acne and sun damage.

Renova (Tretinoin) isn't a cure for fine lines and wrinkles, but it's clinically proven to improve them.

Upsides
  • Benzamycin works better to reduce bacteria in oil glands and improve overall signs and symptoms of acne than either medicine alone.
  • Reduces bacteria on the skin, which "calms" the skin down (lowers the inflammatory response) in acne.
  • Combining an antibiotic with benzoyl peroxide lowers the chances of Benzamycin not working as well over time.
  • Although Benzamycin can irritate the skin, a true skin allergy is rare.
  • Can be used in combination with acne pill medicine if your doctor thinks you need it.
  • You only need to apply it once a day, usually in the evening.
  • Most people who reported having skin irritation said that it was mild.
  • Part of a complete program to help you take better care of your skin.
Downsides
  • There's a risk of irritation with anything you apply to your skin and this is no different. Benzamycin, contains a topical antibiotic and can cause redness, peeling, abnormal dryness or stinging, tightening, or burning sensations.
  • It's rare, that a serious allergic reaction would occur, but it's a good idea to test a small area of skin before using on any larger or sensitive areas
  • Can cause severe inflammation of the large intestine (pseudomembranous colitis).
  • Not the best choice if you're pregnant. Benzamycin is categorized as pregnancy Category C (weight risks vs benefits) because of the benzoyl peroxide part.
  • Can cause bleaching of hair and clothing.
  • You'll need to stay out of the sun or apply a sunscreen if you go outdoors.
  • It may take up to 6 months to see the full benefit for facial wrinkles.
  • Not a good choice for women who want to become or are pregnant
  • Can change the color and texture of your skin if used long-term.
  • You need to be careful about avoiding any sunlight or artificial tanning while using it.
  • It doesn't work for deep wrinkles.
