Is this cosmetics ingredient harmful? My New Year’s goal was to exercise more, and it’s going great! But I’m so sore that it’s hard to keep it up. What can I do to stop the pain?

Q:

Some of my cosmetics have a big sticker noting that they’re free of mineral oil, but others don’t. That makes me wonder: Does mineral oil put my health at risk?

A:

Mineral oil is a derivative of petroleum, which sounds scary, but it’s been safely used in cosmetics for decades because it helps moisturize, soothe and protect the skin barrier. And while there’s some evidence that mineral oil may clog pores and cause acne, there’s no reason to switch if you’re not experiencing symptoms.

While you’re looking at labels, however, there are a few ingredients I do advise avoiding. Fragrance, alcohols (ethanol or isopropyl) and dyes like o-phenylenediamine are common in moisturizers and soaps, but they can dry out and irritate skin, especially if you have cuts or tears that the product can seep into. Additionally, parabens and phthalates, often in shampoos and conditioners, may disrupt hormones. Most cosmetics that don’t have these ingredients are labeled as such, but it’s always wise to check ingredient lists to ensure you’re avoiding the additives.

Q

A

Congratulations on taking steps to reach your goal! The soreness you’re experiencing is normal, and it will go away, but it can take up to 16 weeks for your muscles to acclimate when you begin or expand an exercise routine. Fortunately, you can remedy pain without cutting back on workouts.

First, I suggest swapping one or two of your weekly workouts for tai chi, a type of gentle movement known to increase strength and improve balance. Plus, Tufts University scientists say it can reduce pain by 60% and stiffness by 80%. To find instructional videos, simply search “tai chi for beginners” on YouTube.

To erase aches now, massage sore spots with anti-inflammatory olive oil, which studies show soothes pain more effectively than topical prescription pain relievers.
