Use products designed for your skin type.
Using appropriate products is important no matter your skin type, but it’s especially imperative for people who experience rosacea and have hyper-sensitive skin. Soothing topical ingredients will help to sedate and calm and comfort overactive skin by reducing redness. And, seek out products that are unscented or don't use artificial fragrance. Also listed as “perfume” or “parfum," fragrance is a leading cause of skin flare-ups. Look for words like “gentle,” “anti-redness,” “soothing,” and “calming,” and products that contain the following ingredients:
Chamomile extract: provides anti-redness and anti-inflammatory benefits
Azulene extract: calms and soothes the skin
White tea: This natural antioxidant helps calm the skin by inhibiting reactive stress brought on by UV rays, tobacco smoke, and urban smog.
Avoid over-exfoliating your skin.
Skin peels, topical AHAs (alpha hydroxy acids), retinols, and professional microdermabrasion, while sometimes helpful in smoothing the skin, can break down its protective lipid barrier, causing it to become inflamed and reactive. It’s important to consult with a professional aesthetician to determine the level of exfoliation that's most appropriate for your skin type.
Repair your skin’s moisture barrier.
The skin has a moisture barrier made of natural lipids. When it's damaged, tiny, invisible cracks appear, allowing moisture to escape, which can cause dry, flaky skin and increase the potential for irritation — even sensitive skin products can begin to give you a stinging, irritating sensation.
Do a patch test.
When in doubt, do a patch test. The best place to test-drive skin-care products is the side of the neck. Apply a small amount, rub it in, and wait 24 hours. If there isn’t a negative reaction, you should be fine using it on your face. However, if redness or irritation occurs, avoid it.
Keep skin-care products cold, and avoid hot water.
Hot temperatures increase heat in the skin, making it more sensitive and red. When possible (and especially when it's hot out), store your skin-care in the refrigerator. Cleansing, toning, and moisturizing with cooled products will constrict the capillaries to ease redness and irritation. When washing your face, use lukewarm or cool water to help avoid redness.
Parsol 1789 (avobenzone): a common sunscreen agent that may cause skin sensitivity and inflammation.
High doses of ascorbic acid, L-ascorbic acid, or alpha-lipoic acid: These acid forms of vitamin C can increase skin sensitivity. Instead, choose no-sting vitamin C ingredients, such as magnesium ascorbyl phosphate.
Essential oils: People with rosacea may find their skin easily irritated with oils containing cinnamon, clove, geranium, or peppermint.
Sodium lauryl sulfate, sodium laureate sulfate, and ammonium laureate sulfate: These compounds act as cleansing agents, but they're often too harsh and strip water out of the skin.
