Acne scars on your face can be notoriously difficult to get rid of, even with in-office treatments like lasers, dermabrasion and collagen induction.

"To some extent, time will improve the scars," says Deirdre Hooper, MD, co-founder of Audubon Dermatology in New Orleans. But there are some natural remedies for acne scars that may help, too. Just be careful which you use.

Here's what we know about ways to help get rid of acne scars naturally, including some methods that aren't worth the time or money.

1. Zinc

Everyone should wear sunscreen, but it's especially important when you have acne scars.

Specifically, we mean zinc- (or titanium-) based sunscreen.

If you have acne scars, especially dark (hyperpigmented) scars, the most important thing you can do is to stay out of the sun, Dr. Hooper says. This will prevent the marks from getting worse.

Most zinc sunscreens have a white tint, which can present a problem for people of color, who are prone to darker scars, says Dr. Hooper. She suggests looking for a tinted sunscreen, like Supergoop! CC Screen ($39, Amazon.com).

The American Academy of Dermatology recommends everyone use broad-spectrum (protection against UVA and UVB rays), water-resistant sunscreen with an SPF (sun-protection factor) of 30 or higher every time you go outside. "The sun is very potent," Dr. Hooper says.

2. LED Lights

LED masks have to be used regularly to make a difference.

This may seem counterintuitive given the recommendation to wear sunscreen, but LED (light-emitting diode) lights are anti-inflammatory and don't emit any ultraviolet rays. Look for a combination of blue and red (the different colors represent different wavelengths).

"You have to be diligent," says Diane Madfes, MD, assistant professor of dermatology at Mount Sinai School of Medicine in New York City, who recommends products like the Priori UNVEILED LED Mask ($429, PrioriSkinCare.com), which can be used at home.

LED lights have also shown promise for wrinkles and age spots, although the big studies have not happened yet, according to Harvard Health Publishing.

3. Vitamin A

Retinol creams can serve as a home treatment for scars.

Vitamin A is an ingredient in Retin-A, a popular prescription medicine for acne, and in retinol products, which are available over-the-counter.

Creams containing vitamin A, which work by helping skin cells turn over more effectively, can also help alleviate acne scars, especially textural scars like rolling or boxcar scars.

"A lot of them are encapsulated in oil so they're more soothing to the skin," Dr. Madfes says.

Try These Products With Retinol

  • Differin Gel ($12.88, Amazon.com)
  • CeraVe Resurfacing Retinol Serum ($19.99, Ulta.com)
  • RoC Retinol Correxion Night Serum ($21.95, Amazon.com)

4. Vitamin C

Vitamin C may be able to help lighten darker acne scars, says Dr. Madfes, who recommends using topical (on-your-skin) formulations twice a day.

Like other antioxidants, vitamin C works by diminishing harmful free radicals and inflammatory molecules, Dr. Hooper says.

Some vitamin C formulas are unstable when they hit air and oxidize. That's why Dr. Madfes recommends the SkinCeuticals and BeautyStat brands.

5. Fruit Acids

"Fruit acids are natural exfoliators that increase cell turnover and can potentially smooth and thin out scars," says Shoshana Marmon, MD, PhD, assistant professor of dermatology at New York Medical College. Examples of fruit acids include glycolic, lactic and citric acid.

Kojic acid, available in over-the-counter products, may also play a role. "It's derived from fungus and helps to lighten dark spots by blocking a key step in the production of melanin," Dr. Marmon says.

Ferulic acid may decrease scar thickness by inhibiting collagen thickness, she adds.

Try These Products With Acids

  • SkinMedica AHA/BHA Exfoliating Cleanser ($39.95, Amazon.com)
  • Alpha-H Liquid Gold With Glycolic Acid ($54, Sephora.com)
  • Naturium Tranexamic Topical Acid 5% ($20, Amazon.com)

What About Aloe Vera?

While aloe vera seems to be an effective antidote for acne (not to mention burns), it has limited use in improving acne scars, Dr. Hooper says.

One January 2016 study in the ​Annals of Plastic Surgery​ investigated whether aloe vera could heal scars in rats. It could, but bear in mind that rats are not humans. What's more, not all scars are created equal. Some folks mistakenly believe that a compound that will ​fade other scars will also work against acne scars. Un​fortunately, this isn't so, Dr. Hooper says.

What About Vitamin E?

Contrary to widespread reports on the internet and elsewhere, there's little science to back up the claim that vitamin E helps heal acne scars.

In fact, there's little evidence to suggest it can resolve any scars. September 2010 research in the ​Journal of Plastic, Reconstructive & Aesthetic Surgery​ found that vitamin E did help post-surgical (not acne) scars in children, which may be where this pervasive myth comes from. Another study a decade earlier, in Dermatologic Surgery, found that vitamin E had no effect on scars from skin cancer.

Bottom line: "I don't recommend it," Dr. Madfes says.

What About Black Seed Oil?

Also known as Nigella sativa, black seed has been used for centuries to treat not just skin disorders but also bronchitis, rheumatism and diarrhea.

The evidence for any dermatological use is slim to none.

One report from July 2015 in the ​Journal of Dermatology & Dermatologic Surgery​ found that the oil helped clear acne, but the authors did not look specifically at acne scars. A study 20 years earlier concluded that Nigella sativa oil might reduce inflammation (which contributes to scars), but the study was only conducted in rat cells.

What About Rosehip Seed Oil?

The authors of a June 2015 study in the ​Journal of Cosmetics, Dermatological Sciences and Applications​ concluded that rosehip seed oil could speed recovery from post-surgical scars. Again, though, the study did not look specifically at acne scars which can be different from other types of scars.

There's also little evidence that chamomile oil and other essential oils clear acne scars. Nor do honey and other natural remedies shown to help open wounds including acne, Dr. Hooper says.

What About Chamomile Tea?

Although tea in general has antioxidant and anti-inflammatory properties, you'd probably be better off drinking it than applying it to your skin, says Dr. Hooper. Chamomile tea, then, doesn't help with acne scars. Neither do chamomile tea bags.

In order to heal acne scars, you have to stimulate collagen, a protein which helps your skin stay strong and tight. Vitamin C may help, but not tea.

What About Lemon?

Another resounding "no" for lemons, lemon juice and other citrus fruits and derivatives.

"Lemons and limes have some antioxidant properties, but they can't penetrate deep enough to make a difference," says Dr. Hooper.

Lemon, an exfoliant, is also irritating and makes your skin more sensitive to light, says Michele S. Green, MD, a dermatologist with Lenox Hill Hospital in New York City. This brings us back to zinc, which will prevent sunburn and won't aggravate your scars.

What About Baking Soda?

Baking soda is a natural exfoliant and may help acne when applied judiciously to pimples (as opposed to your whole face), says Chris G. Adigun, MD, a board-certified dermatologist with Dermatology & Laser Center of Chapel Hill. But there's no evidence that it smoothes scars.

Like many other supposed natural treatments, it can't penetrate to the deeper layers of skin that are damaged by acne scars. "When the damage is so deep, we have to find other ways to stimulate collagen production," says Dr. Madfes. "That's the really hard part."

Rice powder along with oats and egg fall into the same bucket: No good reason to try them for acne scars.

What About Apple Cider Vinegar?

Apple cider vinegar contains lactic acid, an exfoliating agent that may help improve the appearance of acne scars, says Dr. Marmon.

But there's one big caveat to ACV and other natural remedies: You may waste valuable time.

"There's a magic window from six to 12 weeks when you want to use lasers to realign the collagen and get scars to fade faster and heal better," says Dr. Madfes. "Sometimes you can sit on it too long."
