Buzzy skin-care products and ingredients are everywhere we turn, from our Insta-feeds to magazines. This spring, we’ve seen four major ingredient trends take off: manuka honey, matcha, avocado and prebiotics. We chatted with Dr. Nava Greenfield from Schweiger Dermatology Group in Brooklyn about what each of these ingredients do and rounded up our favorite products to add them to your skin-care collection, stat.Manuka HoneyAccording to Dr. Greenfield, manuka honey may as well be a gift from the skin-care gods, thanks to its soothing properties. You can find the ingredient in the L’Oréal Age Perfect Hydra Nutrition Manuka Honey All Over Balm. It’s also made with nurturing oils and works to soothe and rescue dry skin on the face, neck, chest and hands and feels like luscious treat with every use. Avocado Although Dr. Greenfield says to proceed with caution before using this buzzy ingredient, “avocado oil has a moisturizing effect on the skin,” she says. If you want to give it a try, we highly recommend the Glow Recipe Avocado Melt Sleeping Mask, which is a creamy overnight treatment formulated with four forms of avocado (plus, it also has manuka honey). It is completely free of parabens, sulfates and formaldehydes — and is just as green and lush as a ripe avocado.Prebiotic “The idea of prebiotics is that it could support the healthy microbiome on the skin, although there is not a ton of research published on this yet,” says Dr. Greenfield. If you have acne- prone skin and want to take the dive, try the La Roche-Posay Lipikar Balm AP+ Intense Repair Moisturizing Cream. Built for the face and body, this intense repair moisturizing cream helps replenish skin’s natural lipids and provides up to 48 hours of hydration. It is made with the La Roche-Posay Prebiotic Thermal Water and is approved by the National Eczema Association. Plus, it’s been clinically tested and shown to reduce dry, rough skin.   MatchaThis popular ingredient is making its way in skincare rounds, from cleansers, to hair and nail products alike. “The thought behind matcha is that it can be detoxifying,” according to Dr. Greenfield. We recommend giving the Milk Makeup Matcha Detoxifying Mask a try for a detoxifying matcha cleanse. Apply to damp or dry skin and let dry for five to ten minutes before rinsing off with warm water. You can use this two to three times a week, though you’ll definitely be tempted to use it more.
