10 ways to score glowing, radiant skin

1. Exfoliate!

The sun, lack of vitamins, poor skincare habits and fluctuating hormones can lead to a dull complexion. Get your glow back by using an exfoliating formula to remove dead skin cells and stimulate new ones, the International Dermal Institute recommends. Try a scrub that contains organic materials like salt and sugar, or synthetic beads. You might also consider formulas with exfoliating chemicals like retinol, alpha-hydroxy acids (e.g., glycolic) or beta-hydroxy acids (e.g., salicylic). Go easy at first (no more than twice a week), especially with sensitive skin. Or talk to a dermatologist about stronger concentrations, available by prescription only.

Bonus: Freshly exfoliated skin absorbs serums, moisturizers and other products more easily.

2. Drink your salad

Crave A-list skin like that of Drew Barrymore and Jennifer Aniston? Then tap into their secret weapon: celebrity nutritionist Kimberly Snyder's antioxidant-loaded Glowing Green Smoothie, from her new book The Beauty Detox Foods. Whirl the ingredients listed below on a blender and drink some every morning to give your skin a boost from the inside out.

Glowing Green Smoothie (makes 60 ounces)

- 2 cups very cold filtered water
- 7 cups chopped spinach (high-calcium dairy substitute)
- 6 cups chopped romaine lettuce (contains protein)
- 1 1/4 cups chopped celery (contains vitamin B1, B2, B6 and C)
- 1 apple, cored and chopped (a fibre-rich alternative to instant oatmeal)
- 1 pear, cored and chopped (this fruit is high in fibre and has vitamins C, E and K)
- 1 banana (high potassium)
- 2 tbsp lemon juice (filled with vitamin C)

3. Workout

Hitting the gym three times a week is a great way to work up a rosy glow. Not only does exercise-induced sweat help cool your body, the oxygenated blood pumping to your skin also leaves a healthy flush on your cheeks, says Dr. Nowell Solish, a dermatologist and founder of the Sweat Clinics of Canada. Make the most of your workout by exercising makeup-free and drinking lots of water throughout your session. Then hit the shower as soon as possible, so you can wash away unwanted dirt and reveal a fresh complexion, says trainer Andrea Gladwin, owner of Results Oriented Fitness in Toronto.

4. Add a serum

These skin essentials work like foundation garments: They lift, support and protect and should be worn under everything else. They typically contain high concentrations of radiance-enhancing ingredients like vitamins, antioxidants and essential oils. So when you put one on, you can't go wrong.

5. Get your beauty sleep

A new study published in the British Medical Journal found sleep-deprived people look less attractive. Appear more rested by making sure you get a solid seven to nine hours of shut-eye every night. "Block out sleep time and make it sacred," says sleep expert Fern Toop, owner of Saskatoon's Prairie Meadow Sleep Scoring. Then give your skin an extra boost by adding a hydrating night cream to your evening routine. Toop also suggests powering off anything with a lit screen (like a cell, laptop or TV) about one hour before turning out the lights. "Blue wavelengths emitted from a screen can disrupt melatonin, which is key for sleep onset," says Toop.

6. Screen out the sun

Taking your pooch outside is no walk in the park if you're not covered from head to toe with a broad spectrum SPF that protects you from the sun's harsh rays: UVA (aging) and UVB (burning). Health Canada recommends:

1. Wear a lotion with an SPF of at least 15.
2. Choose a sweat- and water-resistant product whenever possible.
3. Read the label's instructions to make sure you put it on properly.
4. Apply sunscreen at least 20 minutes before you go outside.
5. Reapply sunscreen often, especially if you're sweating or swimming.

7. Hydrate

You need to drink about nine cups of water a day to feel energized, regulate temperature and stay hydrated. The good news is you can eat your H2O too, says research from the University of Kentucky. Water-rich foods like tomatoes, celery, cantaloupe, grapefruit, cucumber, strawberries and watermelon contain at least 90 percent water when eaten raw. Quench thirsty skin by choosing day creams (one for your face, another for your body) that list micronutrients from these fruits and vegetables, along with hyaluronic acid (it can hold over 1,000 times its weight in water), as ingredients.

8. Fight wrinkles

Certain ingredients have earned a solid reputation as fine-line erasers, especially the double threat of retinol (a.k.a. vitamin A) and vitamin C. Experts say retinol boosts collagen production and soften crow's feet, while vitamin C in high amounts fights damage from free radicals caused by the environment, pollution and the sun. Beauty insiders also suggest keeping your eyes open for another superhero ingredient: coenzyme Q10, the antioxidant all-star. It also helps neutralize free radicals.

9. Remove your makeup

Wake up looking like a racoon more often than not? Last night's mascara, foundation and blush can wreak havoc on your eyes and face. Ophthalmologist Dr. Hilary Beaver from the University of Iowa reveals that sleeping with makeup or makes you more susceptible to allergic reactions and eye irritation. Acne breakouts, excessive dryness and flaking skin can also occur. "Makeup is thick and can clog your pores," says Toronto dermatologist Dr. Lisa Kellett. Considering it takes 14 days for new skin cells to move from the lowest layer of your epidermis all the way up to the top, that's a lot of trapped dead skin.

Break the habit: Stock up on makeup towelettes. They're a quick and easy way to wipe your skin clean.

10. Pucker up

Did you know that a little loving can help prevent wrinkles? In a recent study on chemical attraction, psychologist Wendy Hill at Lafayette College in Pennsylvania discovered that kissing can lower cortisol levels. Otherwise known as the stress hormone, cortisol helps maintain our blood sugar levels, immune system and blood pressure and the functioning of the central nervous system. When we feel stressed, this hormone goes into overdrive and can leave us with extra weight around our bellies, feelings of depression, restlessness at night and, yup, unwanted fine lines and wrinkles on our faces. So take time for a little make-out session — and don't forget to keep lips nice and hydrated with natural balms.
