Preliminary data has shown that wheat-based phytoceramides improve hydration to maintain healthy-looking skin as well as reduce irritations, says Dr Eileen Tan, consultant dermatologist and a Shape advisory board member. She adds: "However, while they are safe for most, people with a gluten sensitivity or wheat allergy should avoid taking them."
2. SPF protector
Supplements like Heliocare Oral (from S$57.75, Watsons) with the plant-derived anti-oxidant fernblock can help to prevent sunburn and UV-related ageing 30 minutes after consumption. "They are useful in situations when you forget to reapply your sunscreen, but don't rely on them solely to shield you from UV rays," says Dr Cheong Wai Kwong, consultant dermatologists and Shape advisory board member. He recommends using topical sunscreen as well for maximum protection.
3. Youth enhancer
Hyaluronic acid is found in your body and keeps skin moist and supple. Over time, the amount depletes and wrinkles start to form. A 2001 study in the Journal of New Remedies & Clinics found that ingesting it increased skin's moisture content. Excellent sources include kelp, sweet potato and avocado.
"Glutathione, one of the body's most powerful antioxidants, may have some clinical efficacy in skin whitening," says Dr Tan. It is found in raw goat's whey and avocado. When eaten regularly, it reduces pigmentation and melanin production.
5. Skin firmer
Collagen gives skin its firmness but when consumed orally, it may not necessarily make its way to your epidermis. That's because your body digests it like any other protein and breaks it down into amino acids. These amino acids in turn create collagen protein. Your best bet is to get it from food sources rich in the amino acids hydroxylysine and hydroxyproline, like egg whites and lean meats. And as some studies have shown that vitamin C stimulates collagen production as well, time to load up on your kiwi fruit!
