While skincare is poised to become a bigger shopping category for a lot of people, those with sensitive complexions might need a bit more help understanding their skin\u2014even scientists admit that it can be complex. We reached out to a dermatologist for key advice pertaining to your delicate skin type, with the goal of boosting your confidence the next time you\u2019re buying new products.

Rosacea-prone skin to flushing, stinging, and burning as well,\u201d she explains. Other factors that can compromise your skin\u2019s barrier function (the protective outermost layer of the epidermis) include sun exposure, pollution, and stress.3.

It helps to replenish , seal in small cracks to make the skin supple and smooth, and also prevents irritants and allergens from entering," says Dr. Shi. So, slather away.4. It's important to scan skincare labels carefullyIf you're sensitive but want to experiment with new products, being cautious is a good thing. To avoid upsetting fragile skin, stick with gentle, fragrance-free formulas that are designed for sensitive skin and will replenish much-needed moisture. Opt for rich, creamy cleansers (they won\u2019t strip like sudsy soaps) and nourishing face lotions and creams for day and night. We\u2019re into Burt\u2019s Bees Sensitive Skin line, which contains soothing rice extract and aloe, plus cotton extract, which helps fight off irritants. As for what to avoid, Dr. Shi recommends steering clear of ingredients that can cause contact dermatitis or excessive dryness, like fragrance, sodium lauryl sulfate (also known as SLS), synthetic dyes, formaldehyde, and preservatives like parabens. \u201cAlso, watch out for over-the-counter acne products with benzoyl peroxide, which can cause irritation, and things that contain a lot of alcohol. Most products will have some, but if you put an item on your finger and it evaporates quickly, that means it\u2019s a very alcohol-based product,\u201d says Dr. Shi. 5.

Your skin can suddenly become sensitive as you age\u201cThe most common demographic for sensitive skin syndrome is women in their 40s and 50s,\u201d says Dr. Shi. \u201cOne theory about this is that you\u2019ve had 10 to 20 years to develop a reaction. You've been exposed to all these chemicals and the more prior exposure you've had to certain ingredients, the higher the risk of being allergic to them,\u201d she explains. No matter what your age, if you notice sensitive skin symptoms have started popping up, consider going to a dermatologist. \u201cGet an evaluation and make sure there is no other skin disease or condition that may be causing symptoms, such as atopic dermatitis or rosacea,\u201d says Dr. Shi.
