Libby Rhee, MD , a certified dermatologist in New York City, told the Post. "It's good to change products about every two months, but sometimes, when a product works for you, you use it. "

Frequently asked questions about skin care
Learn all of the skincare basics you need for your next Sephora shopping trip, but first, here's an insight from our experts:
- Hadley King, MD : A New York City Dermatologist specializing in medical and cosmetic dermatology. She is also a clinical dermatology instructor at Weill Cornell Medical Center.
- Libby Rhee, MD : Board Certified Dermatologist based in New York City who also specializes in cosmetic and medical dermatology, natural rejuvenation, and preventive aging. Treats about 70% of all skin types, men and women. She is also a clinical dermatology instructor at Mount Sinai Medical Center.
Which products should I include in my skin care routine and in what order?
"In general, the idea is to gradually move from lighter products that are more absorbent to heavier products," said Dr. King.
Dr. Rhee recommends a simple routine in the morning (cleanser, serum, moisturizer, and sunscreen) and an advanced line in the evening, depending on your preferences. In the following he explains each product and its advantages:
- Cleaner : Important for removing dirt and grime from the skin during the day to leave a clean surface.
- Toner : Useful for unifying the skin when it is oily.
- Essence : Moisturizes and can balance the skin.
- Serum : means that it contains antioxidants and other nutrients in the skin that help repair and protect skin damage.
- Prescription Medicines For The Face : If recommended by your doctor, may be for acne.
- Moisturizing : Helps create a nice healthy skin barrier so it isn't too sensitive to environmental influences and protects dry skin that is showing accelerated signs of aging.
- Sunscreen : It protects us from skin cancer and advanced photoaging.
If you'd rather use an eye cream, apply it after the serum, adds Dr. Rhee added.
What ingredients should I look for in a moisturizer if I have dry, oily, acne-prone, or mature skin?
According to Dr. King all moisturizers should contain humectants, emollients, and occlusive agents. Here is a breakdown of all three:
- Humectants : like hyaluronic acid and glycerine, these are mainly low molecular weight substances that bind water in the stratum corneum. They must be used with the other components to maintain the water content.
- Emollients : such as cholesterol, squalene, fatty acids, fatty alcohols and ceramides, these are saturated and unsaturated hydrocarbons that support the skin's barrier function, membrane fluidity and cell signaling, thereby improving the texture and general appearance of the skin.
- Occlusive : like petroleum jelly, beeswax, mineral oil, silicones, lanolin and zinc oxide, these are oils and waxes that form an inert layer on the skin and physically block the transepidermal water loss.
"Moisturizers for all skin types should contain these three components, but dry or mature skin may need stronger occlusions," adds Dr. King added. "If you have oily, acne-prone skin, avoid all comedogenic ingredients like coconut oil, and lighter occlusions may do the trick."
How do I know what skin type I have?
"Those with oily skin regularly have shiny, oily skin in their T-zone and can look oily outside of the T-zone," said Dr. King. "People with dry skin regularly dry out. "
In addition, Dr. Rhee skin types don't like being "mixed".
"Often times, when you're oily in your T-zone it means it's a combination with dry areas in other places, which means your skin is likely out of whack," he said. "This could be due to the use of harsh ingredients or excessive washing.
What ingredients should I look for in a cleanser if I have dry, oily, acne-prone, or mature skin?
For dry and mature skin, Dr. King mild detergents that contain no harsh detergents and that contain moisturizers, emollients and occlusive agents to support the skin barrier and provide moisture during the cleansing process.
She recommends salicylic acid cleaners for oily skin prone to acne.
What is salicylic acid?
"Salicylic acid is a great pore cleansing ingredient because it exfoliates the surface of the skin and penetrates the pores to remove sebum," said Dr. King. "It's a great ingredient for people with oily and acne prone skin, and for treating and preventing comedonic acne such as blackheads and pimples. "
Specifically, salicylic acid is a beta-hydroxy acid that is used to chemically exfoliate the skin. "They break the bonds that hold dead, dull skin cells on the surface of the skin, so that the skin is gently peeled off and smoother, more radiant skin is visible underneath," he adds.
What is hyaluronic acid?
"Hyaluronic acid is a natural moisturizer that can store 1,000 times its own weight in water," said Dr. King. "This makes it a key molecule involved in hydrating the skin. "
Dr. King adds that it's best to combine moisturizing ingredients like hyaluronic acid and glycerin with emollients and occlusive agents to lock in moisture and keep your skin hydrated, especially if you have dry skin or live in a low-humidity environment.
What is niacinamide?
"Vitamin B3, or niacinamide, has been shown in several studies to help reduce certain signs of aging, particularly skin tone and texture," he said. "Niacinamide serves as a precursor to molecules in the body that are responsible for cell proliferation, repairing cell damage, and other biochemical needs."
In addition, it is a powerful antioxidant that brightens the skin by reducing hyperpigmentation and redness. Niacinamide also increases the production of ceramides in the skin, which help strengthen the skin's barrier and prevent moisture loss, according to Dr. King.
Niacinamide can also be used safely on a daily basis, adds Dr. King added. "The results will improve with regular use. Look for products that contain 5% niacinamide, the percentage that has been shown to make a visible difference without causing irritation. "
What is citric acid?
"Citric acid is another form of vitamin C that is a different type of chemical peel, another alpha hydroxy acid that speeds skin renewal," said Dr. Rhee. It can also be found in many of the Sephora bestsellers listed above.
What is the essence of skin care?
"It's basically a diluted moisturizer that rebalances the skin because it's not as heavy as a moisturizer or as thin as a toner," said Dr. Rhee. "If you're short on time or don't want too many things, gasoline would be the first thing to do because it's not that important."
How is caffeine a useful ingredient in skin care?
"Caffeine narrows the blood vessels and therefore can reduce swelling," said Dr. King.
Dr. Rhee went on to explain that caffeine is a powerful ingredient. "Caffeine is an antioxidant and it narrows the nose so it squeezes the blood vessels a little," he said. "If you have a tan, purple, or even green tint under your eyes, it's because you have more blood vessels there, so caffeine helps narrow those blood vessels in a safe way."
How is Vitamin C a Beneficial Ingredient in Skin Care?
"Vitamin C is an essential component of healthy skin, both as an antioxidant and an essential factor in collagen synthesis," said Dr. King. "Vitamin C contributes to sun protection, reduces photodamage and is necessary for wound healing as well as protection against free radicals from other sources, such as environmental pollution."
In particular, vitamin C helps lighten the skin and prevent and reduce dark spots caused by UV rays, adds Dr. King added.
How Often Should I Apply Moisturizer?
According to Dr. King, the moisturizer should be applied after cleansing and at bedtime. If you have dry skin, you may need to apply moisturizer more frequently, she adds.
"The difference between gels and moisturizers is simply the amount of emollients they contain," said Dr. Rhee. "The gels have less than the creams, so the creams will be more moisturizing if that's what you look for."
How often should i apply a cleaner?
For most people, cleaning the face twice a day is enough, says Dr. King.
What is the difference between an eye serum and an eye cream?
"A serum is generally lighter, more quickly absorbed, and contains stronger active ingredients and lighter moisturizers, while a cream is thicker, more moisturized and may not have as powerful active ingredients," said Dr. King. "A serum can also be followed by a cream to stimulate moisture."
In addition, Dr. King that both are helpful to complement your skin care routine, as the delicate skin around the eyes is particularly prone to irritation, fine lines, dark circles, and puffiness. "Individuals with puffiness should look for an eye cream or serum that contains caffeine to narrow blood vessels and reduce puffiness, while those with fine lines should look for antiaging peptides, growth, and retinol. "
Can I use toner to remove makeup?
If you're wearing light, oil-free, water-based makeup, a toner might be enough to remove makeup, said Dr. King. In most cases, however, she recommends a makeup remover and / or detergent.
"There is a caveat with tonics: you should choose a mild, neutralizing agent so it doesn't rub your skin," adds Dr. Rhee added. She recommends using micellar water as it is water that acts like an oil so you don't have to use too much force or use strong ingredients found in some wipes to remove makeup.
How do I know which skin care masks to buy?
"People with dry skin can benefit from a mask that contains moisturizers [like hyaluronic acid], emollients [like ceramides], and moisturizers," said Dr. King. "People with oily or acne-prone skin can benefit from an clay-based mask because the clay absorbs excess sebum. "
Dr. King adds that anti-inflammatory ingredients like vitamin C and green tea can help soothe irritated skin.
"If your skin is beautiful and balanced and doesn't feel dry to the touch, I recommend exfoliating or masking once or twice a week if your skin is a little lazy or you want that extra glow," said Dr. Rhee. "You don't want anything that's too tough or has big bills; As a general rule of thumb, if it's too difficult to put your hand on a young child, I wouldn't put it on their face.
What ingredients should I look for in sunscreen?
Dr. King advocates the use of non-comedogenic mineral sunscreens. "I recommend physical sunscreens (zinc oxide and titanium dioxide) because they sit on the skin to diffuse and deflect ultraviolet rays and physically keep them from penetrating the skin," he said. "They typically contain a combination of two to six of these ingredients: oxybenzone, octinoxate, avobenzone, octisalate, octocrylene and homosalate."
For tinted moisturizers and other make-up products with a sun protection factor, Dr. Rhee always use a traditional sunscreen for the face. "If you want an SPF-tinted moisturizer it's usually an extra honor, but when people aren't using traditional sunscreen, they don't reapply as often to protect their skin from the sun."
