I'm always telling my clients put your money in your serums, Serums are most important because they are usually repairing or preventing damage. Buying a Vit C Serum from Wal-mart its going to help but it will never get you where you want your skin to be. Dr. Lawrence Samuels, Dermatologist, founder of RX Systems PF, explains it to you best. Here is what he has to say.
It's a beauty misconception that serums are just a more expensive form of skin moisturizer. Yes, the price is more per ounce than your average skin care product, but that's because you're getting more concentrated ingredients (and deeper-penetrating effects). Get the low-down on why serums are worth every penny when you keep reading.
Why use it? A serum is your go-to product to improve the overall look of your complexion. The active ingredient can bring antioxidants to the skin, restore cell growth, or help decrease pore size. But the one thing a serum doesn't do, typically, is moisturize the skin.
How does it work? "Moisturizers have a base that allows them to stay on the surface to moisturize the outer portion of the skin, but a serum has a lipid-soluble base that allows the active ingredient to actually penetrate into the epidermis," explains Dr. Lawrence Samuels, chief of dermatology at St. Luke's Hospital and founder of the Rx Systems PF skin care line.
Which one is right for you? "If you have acne-prone skin, the two most significant ingredients would be an L-ascorbic acid [which is true vitamin C] and retinol," Dr. Samuels says. "They're both antioxidants that improve the cell growth in the outer layer of skin." If you have normal skin, look for alpha lipoic and glycolic acids in the serum ingredient list.
How do you apply it? Use about a pea-sized amount of serum for the face and neck, applying the product about two minutes after your cleanser (not on wet skin). "Hydrated cells allow the active ingredient to penetrate better than dried cells," Dr. Samuels says. Then, wait another three to five minutes before applying your moisturizer. "Moisturizers help restore the keratin protein back to the skin, so they generally have a higher pH," he said. "If you put on your serum then immediately put on your moisturizer, it can somewhat decrease the effectiveness of your serum." Also, it's important to use face serums primarily at night, because UV rays and oxygen can cause them to oxidize — another reason to make sure you always keep a tight lid on your products.
