Oil Serum, 1 fl oz, $29, by S.W. Basics, available in January 2015 at SWBasicsofBK.com
Think of face serums as a concentrated nutrient boost for your skin: They may cost more than your usual skincare product and look smaller, but you only need a few drops of these elixirs every day to keep your face moisturized. Brooklyn-based S.W. Basics takes a less-is-more approach to the matter, with a serum made of only four organic ingredients: Avocado oil (rich in minerals and vitamins), geranium oil (antibacterial and skin-tightening), turmeric (soothing), and coffee oil (nourishing and moisturizing).
For Dry Skin
Replenishing Face Serum, 1 fl oz, $68, by Malin+Goetz, available at MalinAndGoetz.com
Serums can be used under your usual face cream to lock in the moisture --a good addition to your skincare routine during harsh, cold weather. Malin+Goetz's Replenishing Serum does just that, helping you to maintain healthy-looking skin thanks to its botanical blend and hydrating amino acid protein.
For Mature Skin
Bio-Retinoid Anti-Wrinkle Concentrate Oil, 1 fl oz, EDP, $60, by REN, available at RenSkincare.com
Best used before bed, REN's natural serum gives your vitamin A and a retinoid analogue that combats the appearance of wrinkles, and reduces small imperfections and age spots without the irritating effects of synthetic retinol.
For Damaged Skin
Vitamin C, B, E & Ferulic Serum, 1 fl oz, EDP, $110, by Ko'An MD, available at KoAnCenter.com
Hollywood plastic surgeon Dr Chi Chi Kao has his own skincare line, particularly suited for irritated skin or post-surgery recovery. Ferulic acid, an organic compound found in plant cell walls, has anti-oxidant properties, while a cocktail of vitamins optimizes the natural healing process of your skin, reduces dark spots, and smoothes out fine lines.
Consider it the Rolls-Royce of face treatments: A four-week cure to relieve your skin from environmental stress and give it some well-deserved rest. The botanical formula has real calming effects, and can clear out small blemishes overnight.
