10 Summer 'Skin Detox' Tips from Celebrity Nutritionist Paula Simpson

— -- It's the first day of summer, but your skin is stuck in mid-winter? How to freshen up fast? A skin detox -- from the inside out -- might do the trick.

"Most of the time when we hear about detoxes, we assume we are talking about a liver detox," said Paula Simpson, Celebrity Beauty Nutritionist. "If your skin isn’t looking as good as you’d like, a skin detox may help improve its condition and help you look more radiant and healthy for the summer months," Simpson said.

Simpson shared with ABC News her top skin detox tips. Though you don't need to follow every tip below, Simpson says the more you follow, the better the results. For best results, your skin detox should last four weeks.

Bonus: since this skin detox cleanses from the inside our, you should expect to not only look better, but feel better too.

1. Feed your Gut.

"Through food and supplementation, certain strains of probiotics have been shown to re-balance and detoxify intestinal microflora that indirectly have a positive effect on several skin conditions, known as the brain/gut/skin axis," Simpson said. One of the best known probiotic foods is live-cultured yogurt, she said. Bonus if you can make it at home, because, according to her, "many popular brands are filled with high fructose corn syrup, artificial sweeteners, and artificial flavors."

Simpson also recommends miso "one the mainstays of traditional Japanese medicine and is commonly used in macrobiotic cooking as a digestive regulator."

Also from Asia, she suggests Kimchi, n Asian form of pickled sauerkraut typically served alongside meals in Korea. "Kimchi is also a great source of beta-carotene, calcium, iron and vitamins A, C, B1 and B2," she said. Other options: asparagus, garlic and beans - these foods are fuel for good bacteria.

2. Eat your Antioxidants

"Zeaxanthin is a carotenoid and a very strong skin antioxidant that protects your body’s cells from dangerous free radicals," Simpson said. Zeaxanthin is found in leafy green vegetables, yellow and orange peppers, corn, and eggs. "Consuming antioxidant rich foods such as deep-colored berries, peppers, beets, tomatoes help to ward off reactive free radicals that can depress skin immunity and slow down skin metabolism and cellular renewal."

3. Start with Lemon

Start your day off with warm water and squeezed lemon, Simpson suggests. "Lemons are a staple of many detox diets, and there is good reason. They’re packed with antioxidant vitamin C and have an alkaline effect on the body, so it can help restore the body's pH balance, benefiting the immune system."

4. Get your Greens

Kale, spinach, collard greens, Swiss chard -- any dark leafy green will get the job done. Because, Simpson said, they are "rich in detoxifying chlorophyll that binds and neutralizes lingering heavy metals, chemicals and pesticides. Full of vitamins and minerals, greens alkaline-ize the body to re-balance pH and reduce acidity, which is often associated with congested skin."

5. Drink your Tea

Get your green tea daily. "Clinical studies have shown that drinking green tea daily supports skin antioxidant defense against environmental stressors. Teas like nettle, ginger, dandelion, cranberry, and burdock root are known to support digestion, liver, kidney function and stimulate circulation all helping to speeding up toxin removal. Drink two cups of these teas a day for at least one week."

6. Do Supplement

"I love ZSS Clear Skin," she said, "because it’s a complete nutrition based skin detox system working from the inside and out. The formulation includes exclusive naturally derived antioxidants, healthy probiotics and botanicals targeted to support the detoxification organs to bring out skin that is clear, balanced and glowing." Stars like Lisa Vanderpump of Vanderpump Rules and Orange is the New Black's Dasha Ploanco are said to use the product.

7. Do a Mud Mask

Mud masks pull toxins and waste materials out of your skin, unclog pores, and revitalize dull skin, so they’re good for purification anytime, according to Simpson. "To supersize them for a summer skin detox, slather them on, then step into a steaming hot bath to work the ingredients further into skin."

8. Exfoliate

"Whenever you need to slough away dead skin cells and encourage new, younger looking cells to emerge, you need to exfoliate. Try exfoliating a couple of more times than your usual routine for one week. After one week go back to your usual regimen."

9. Go Sweat

Exercise gets your heart beating and your skin sweating, which helps to cleanse toxins from your body. Hot yoga, saunas or steam rooms help to draw out built up toxins in the skin, she said.

10. Cleansing bath

Use your bath to detox your skin by adding a cup of Epsom salts and calming essential oil such as lavender three times per week. "These will draw dirt and other impurities out of your pores, helping your skin to start over fresh."
