What Is Sensitive Skin?

It’s important to note that there is a difference between sensitive and sensitized skin.

“Often, sensitive skin becomes sensitized.

“If you have sensitive skin, opt for fragrance-free and unscented products.

Note that unscented products may not have a noticeable odor, but may contain ingredients that mask odors.”

Byrdie Tip

Along with fragrances, you’ll want to steer clear of dyes.

“Look for dye-free products if you have sensitive skin.”

Instead, consider using hydrating toners with ingredients likeglycerinorhyaluronic acid.”

Sulfates

You’ll often findsulfatesin cleansers to create the foam effect.

While this may feel satisfying (and look aesthetic), this ingredient often does more harm than good.

“Sulfates are usually effective in removing dirt and oil from the skin,” explains Shokeen.

While many people eventually find a retinol or retinoid routine that works for them, others don’t.

Benzoyl Peroxide

If you have acne-prone skin,benzoyl peroxidemay be your best friend.

And like many of the ingredients on this list, when used appropriately, it can work magic.

That said, the experts say to use it cautiously to avoid any irritations.

“Utilizing benzoyl peroxide could irritate the skin even further.”

Murphy-Rose adds thatpolyhydroxy acids(PHAs) likegluconolactoneare gentle, hydrating alternatives.

Parabens

Parabensextend the shelf life of your favorite products and help prevent any bacteria or mold growth.

But, unsurprisingly, an ingredient that can do these things is not always the most skin-friendly.
