  4. Real Lip Service A greater color contrast between your lips and your skin will make you look more feminine, according to research. A rich scarlet, like Maybelline New York SuperStay 14HR Lipstick in Ravishing Rouge ($9; drugstores), creates a significant distinction for all skin tones.
  5. To Dye For Red hair dye fades more quickly than other shades because the color molecules are larger, so hair strands have a hard time holding on to them. To prevent red dye—or any color—from washing out, use Redken Color Extend Shampoo ($13.50; redken.com for salons).
  6. Rosy Outlook Sniffing scents with linalool, a compound found in roses, can reduce the activity of stress-activated genes, according to animal research. Next time your nerves are frayed, apply lotion with rose notes, such as Olay Body Lotion in Silk Whimsy ($4; drugstores). Green
  7. Little Green Giant Alguronic acid—derived from tiny chlorophyll-rich microalgae—has demonstrated a big anti-aging impact; it’s even more effective at boosting elastin production and cell turnover than retinol, according to studies commissioned by Solazyme, a San Francisco biotechnology company. Find it in Algenist Firming & Lifting Intensive Mask ($52; sephora.com).
  8. Super Skin Brightener Combat a dull complexion with First Aid Beauty Facial Radiance Pads ($28; firstaidbeauty.com), which contain the skin resurfacer glycolic acid, as well as cucumber (it prevents irritation, so you see glowing skin—not redness).
  9. Hair Lifter Cooling peppermint and refreshing eucalyptus keep your scalp from getting sweaty, so hair doesn’t go limp in hot weather. Find them both in John Frieda Root Awakening Lift + Refresh Root Spray ($7; drugstores). (See how you can get away with last-minute hair.)
  10. Headache Helper Sniffing green apple may ease a migraine. In one study, when people in the midst of a migraine attack smelled the scent, their pain lessened more than when they weren’t smelling anything.
  11. Soothing Shades Green-tinted eyewear, such as these Tory Burch sunglasses in Style 6016 ($145; sunglasshut.com), may be better than the proverbial rose-colored glasses.

  12. Stimulating Scent Smelling rosemary may help you improve your memory, according to research from the University of Northumbria in the United Kingdom. Find the invigorating note in 21 Drops Focus Aromatherapy Oil Roll-On ($29; 21drops.com). Yellow
  13. Flower Power Oil extracted from dandelions can help moisturize and soothe a dry, itchy scalp. Find the strand-saving ingredient in Davines NaturalTech Purifying Shampoo ($25; davines.com for salons).
  14. Mega Moisture If you have dry skin, consider taking 360 mg of borage seed oil daily. Researchers have found that supplementing with this amount increases the barrier function of skin, decreasing water loss over time. Try Whole Foods Cold Pressed Borage Oil Soft Gels Supplements ($19 for 90; Whole Foods).
  15. Pretty Happy Lips The key to contentment is under your nose when you use Eos Lip Balm SPF 15 Smooth Sphere in Lemon Drop ($3.50; drugstores). The lip protector contains lemon oil—a sniff of which can improve your mood, according to research.
  16. Liquid Gold Update a nude lipstick for spring by topping it with a golden gloss. “It enhances and adds warmth to the color and reflects light off of lips to make them look plumper,” says makeup artist Emily Kate Warren. Try Lancôme Juicy Tubes in Touched by Light ($18; lancome-usa.com).
  17. Rise and Shine Start your day off bright with yellow; the sunny hue is associated with happiness and a positive emotional state, according to several studies. For a glowing complexion (and mood!), wash with a yellow Clarisonic Mia Sonic Skin Cleansing System ($119; clarisonic.com).
  18. Fountain of Youth Spray on a grapefruit scent, such as Dove Go Fresh Energizing Body Mist ($4; drugstores), for an instant youth boost. When others smell the zesty scent, they judge you to be up to 5 years younger.
  19. Redness Reliever In a study conducted by the National Rosacea Society, 54% of rosacea sufferers said they use yellow-based makeup to offset redness (the shade has a neutralizing effect). If your face flares—whether from rosacea, a sunburn, or sensitivity—dust on Clinique Redness Solutions Instant Relief Mineral Pressed Powder ($32.50; clinique.com), a sheer, yellow-tinted powder with anti-inflammatory caffeine.

  23. Seasonal Aroma Sweet-smelling bluebells burst into bloom in April and May. If you don’t live near a wildflower preserve, you can still indulge in the spring-has-arrived scent by stocking your bathroom with a bottle of Mrs. Meyer’s Clean Day Bluebell Liquid Hand Soap ($4; mrsmeyers.com).
  24. Bruise Clues Snacking on blueberries can help reduce the appearance of any black-and-blue marks. The berries contain flavonoids and vitamin C, which together improve blood circulation to reduce swelling, as well as proanthocyanidins, which help to strengthen the walls of capillaries that are weakened by bruising.
  25. Smooth Remover Prevent irritation when you’re taking off stubborn eye makeup by using a cotton pad soaked in a remover that contains cornflower extract, such as Vichy Laboratoires Pureté Thermale Eye MakeUp Remover for Sensitive Eyes ($16.50; vichyusa.com). The bright-blue flower contains several anti-inflammatory substances, according to a study in the Journal of Ethnopharmacology.

  28. Scalp-friendly Spice Turmeric has been used for hundreds of years as a treatment for hair and scalp issues, according to Dr. Vinod Upadhyay of Maharshi Bhardwaj Clinic and Research Center in Haridwar, India.

  31. Hot Hue Tangerine Tango is the color of the year, according to Pantone. To celebrate, the company teamed with Sephora to create Sephora + Pantone Universe Tangerine Tango Brush Set ($68; sephora.com), a set of five brushes (three shown here) with supersoft bristles in the red-orange hue. They can lend the shade’s uplifting, energizing effect to your morning makeup routine without the color commitment of bright orange lipstick.
  32. Suntan Snack For a healthy-looking glow all over, munch on foods high in beta-carotene, such as orange bell peppers. Eating foods high in carotenoids can tint skin slightly over time, and the subtle color change looks better (and is a lot healthier!) than that caused by the sun. Purple
  33. Eye Enhancer Make brown eyes pop with purple and lavender shadows, like the range found in Almay Intense i-Color Smoky-i Kit for Brown Eyes ($7.50; drugstores). “These hues bring out the golden flecks in the irises of brown eyes,” according to Strand.
  34. Right Light SensatioNail Invincible Gel Polish Starter Kit ($60; Walmart) features a gel nail polish that hardens when exposed to a purple and indigo LED light (included in the kit, and shown here). The resulting manicure has the same staying power as popular salon gel manicures that typically require exposure to (harmful) UV light. But if you’re dead set on going to a professional, here’s how to stay safe at the salon.
  35. Helping Hand Keep your hands healthy and moisturized with a cream that contains lavender oil, like Try L’Occitane Lavender Hand Cream ($22; usa.loccitane.com). The ingredient has been shown to have an antiseptic effect against germs including E. coli, according to a recent study at the Medical University of Lodz in Poland.

  41. Makeup You’ll Dig Beets are “nature’s own lip and cheek tint,” according to Siobhan O’Connor, senior editor at Prevention and co-author of No More Dirty Looks. She suggests cutting a small slice of raw beet and rubbing the juicy side on lips and cheeks for a wash of translucent (read: flattering) pink color that lasts for hours.
  42. Trendy Scent Pink pepper is the up-and-coming fragrance note of the year, according to a team of fragrance experts from Scentsy, Inc. “It’s sweet and floral but also spicy, so it appeals to those who like gourmand fragrances and those who prefer exotic, feminine florals,” says Heidi Thompson, President of Scentsy, Inc. Experience the note in David Yurman Delicate Essence ($85 for 3.4 oz.; Bloomingdale’s).
