You can use face serum twice a day—before your moisturizer—but reserve products with retinol for nighttime. “Generally, most people should be using a treatment serum twice day,” says Hirsch.
Most face serums are safe to be applied twice daily – once in the morning on a cleansed face, before the rest of your makeup, and once at night before bed.
Generally, you should use a serum all over your face and neck twice daily, once in the morning and then again in the evening, before applying your moisturizer if you want to get the most bang for your buck, according to Lamb.
Daily: Cleanser – No matter how much you skimp on your skin care routine, you should always wash your face at least once a day. Those with oily or combination skin may benefit from twice daily washes (morning and night) while drier skin may be fine with just a nightly wash.
You can use your serum(s) both morning and night. They do not necessarily replace your moisturizer but can boost the hydrating effects of your moisturizer. Moisturizers have a simpler job; they are meant to hydrate the skin and prevent water loss.
"But you can absolutely overdo it. Too much of a good thing – like over-exfoliating your skin with multiple acids and/or mechanical beads – can result in redness, irritation, dryness, and worsened breakouts.
Serum/Oil:
If you overuse serum, your skin may not absorb the beneficial ingredients of the product and instead, it will be left sitting on the surface of your face. This could lead to extra oily skin, breakouts and even irritation."
“I definitely recommend serums for anyone who is concerned about aging. It's a really good way to get extra anti-aging effects, more than your typical moisturizer and sunscreen,” says Dr. Waldman.
Is it good to use hyaluronic acid every day? Yup! "Hyaluronic acid is safe and beneficial to use everyday for maintaining skin hydration," says Dr.
Limit to Two Serums Per Routine
We recommend you use no more than two face serums per routine. Again, alternating skin care items is a strategy here. If you have many serums that you like, use one or two in your morning routine and two different serums in the evening.
The ideal age to start using face serums would be late 20s and early 30s. This is the age at which the first signs of aging appears. You can continue using face serums till the age of 50+. Including a face serum in your skincare regimen will not only enhance your skin but also protect it.
To allow serums to fully absorb, apply and wait 5 minutes before moisturizing. Take note: Well-formulated serums absorb quickly and disappear into your skin. If they leave an oily or sticky residue, they're not doing their job well.
While there is no limit to how many serums you can add to your regimen, esthetician Enrique Ramirez, founder of Face to Face NYC, suggests stopping at three. Piling on more products than that is not only time-consuming, it also reduces the chances of each ingredient getting properly absorbed by your skin.
"The fewer products you use on your face, the better," says Michele Green, MD, a board-certified cosmetic dermatologist. "You don't want to overcomplicate things for your skin, especially since your face is so delicate. Giving your complexion a break from skin-care products will let your skin breathe and rest."
Experts agree that the skin only needs three to four products—and sometimes zero skincare products—to thrive.
No, you can start using Vitamin C serum once you are 20.
You are too young to be starting to use toner/exfoliator. In fact, you don't really need to start washing your face until you are 11. For now, if you're really that keen, just wash your face with mild Cetaphil cleanser and then applying lotion.
For teens with uneven pigmentation and dark spots, Sarkar recommends vitamin C, which is brightening, helps build collagen, and has antioxidant action which boosts the strength of SPF.
Can You Use Hyaluronic Acid and Vitamin C Together? Not all powerful skincare ingredients can be mixed, but hyaluronic acid and vitamin C are two that become even stronger when paired with one another. These ingredients can provide both immediate and lasting results when used together in anti-aging formulations.
The reason why people suggest a maximum of two or three serums comes down to layering and penetration. Heaps of brands, salons and experts recommend leaving time between applying your serums and moisturisers, and doing it in a specific order so as to allow all of the ingredients to actually sink into your epidermis.
"Because vitamin C serum helps protect your skin from free radicals, most dermatologists have recommended applying it in the morning to prevent damage during the day," says Joshua Zeichner, the director of cosmetic and clinical research at Mount Sinai Hospital in New York City.
Dr. Robinson advises using serums that'll help with collagen rejuvenation. She recommends using a vitamin C serum (typically in the form of L-ascorbic acid) in the morning for DNA repair, such as to remedy the effects of excess sun exposure. Then at night, opt for retinol to support skin cell turnover.
If all your products (serum, moisturiser, sunscreen etc) already have their fair share of antioxidants, you don't need an extra toner too. Dry skin: If your skin feels tight and dry during the day, you skin needs more moisture. You can either opt for a hydrating toner or a richer moisturiser. It's up to you.
