Like it or not, your skin changes as you age — but how do you know when you’ve reached the point of needing anti-aging skin care? Or when to start using products meant for mature skin? According to dermatologists and estheticians, you can expect to see a noticeable difference around the age of 40 — which is why I consulted five of these skin experts who are 40+ themselves, getting their top tips for transitioning (and maintaining) an effective skin care regimen.

“Collagen production drops more dramatically beginning in your early 40s, which is when many of my patients notice their first signs of sagging skin and fine lines,” shares Dr. Nazanin?Saedi, a board-certified dermatologist and clinical associate professor at Thomas Jefferson University.?“Expression lines such as forehead lines, frown lines and crow’s feet are usually the first to appear.”

The rate your skin changes is determined by a lot of factors, some genetic and some external, so Amy Peterson, medical aesthetician and founder of?Skincare by Amy Peterson?medspa in Miami, recommends taking preventative steps as early as your 30s.

“Skin can change due to external factors like hormones, stress, environment and lifestyle, so it’s important to adjust your routine accordingly and not stay so set in your ways,” she says. Saedi agrees, adding, “Some people think that the skin type they have in their 20s is the skin type they have for life. This is not true. Your skin type can change as you get older as hormones change and sebum production slows.”

So whether you’re starting to see some changes or have already entered a new phase, the experts are here to share five important tips that will actually make a difference in keeping your skin looking and feeling young and healthy.

Hydrate, hydrate, hydrate!

“Mature skin often becomes drier, so using a good moisturizer is essential,” Petersen says. Besides dryness, keeping skin hydrated is one of the first lines of defense against fine lines and wrinkles too. “Incorporating products and ingredients that help drench the skin with hydration will help plump the skin and reduce the appearance of lines,” Saedi explains. She says to look for moisturizers with peptides, vitamin C, niacinamide, snail mucin and growth factors.

Those approaching menopause will especially want to examine whether their current routine is providing enough hydration — Saedi says the hormonal changes of perimenopause and menopause trigger changes in the skin. “When hormone levels lessen, the skin will feel and appear noticeably drier and duller,” she notes. So, the dermatologist says to opt for products that support the skin barrier — “A healthy skin barrier will help the skin stay moisturized longer. Moisturizers with ceramides will help reinforce and repair the skin barrier.”

Add retinol to your routine

Celebrity facialist Shani Darden, who turned 50 this year, says that anyone over 40 should consider adding retinol to their skin care routine. “Retinol is the most effective anti-aging ingredient and one of my absolute favorite ingredients for glowing, youthful skin,” she explains. “Retinol works at the cellular level to address so many different issues from fine lines and wrinkles to dark spots and uneven tone. It’s such an incredible multi-tasker. Retinol not only helps decrease the signs of aging but can also help reverse the signs of aging.”

Don’t skip the SPF

“If you’ve spent too many hours in the sun without sufficient sun protection, you may experience the first signs of aging skin earlier,” Saedi warns. “Repeated sun damage in your teens and 20s can show up as hyperpigmentation, lines and wrinkles as early as your 30s.”

Peterson also emphasizes the importance of wearing sunscreen daily, even on cloudy days. “If you haven’t started before your 40s, start this asap,” she says.

“Remember, it’s not just a sun burn that damages the skin, tanned skin is a sign of sun damage too,” Saedi adds.

Less is more

While it can be easy to get caught up in the excitement of viral products and new launches, the experts agree that simplicity and consistency is key in a skin care routine.

“Skin renews itself over the course of 28 days, a cycle which becomes slower as we age,” says?Tammy Fender, holistic aesthetician and founder of?Tammy Fender?skin care and spa. “So, it’s never about pushing aging skin, which can even cause damage in the long run.” She promotes a “lifestyle-based, holistic approach” to skin health, which means prioritizing sleep, a healthy diet, physical activity and reducing stress, alongside a gentle skin care routine.

If you have specific skin concerns that you want to address (pigmentation, sagging skin, dry skin, etc.), Peterson recommends finding a trusted expert that has an aesthetic approach that matches yours, so you can develop a plan of action to best address your skin goals.

For those just building a solutions-based routine, Peterson says that pigmentation is a good place to start. “Almost anyone in this age category who has never done anything is going to have pigmentation to some degree caused by sun damage. It’s something you’re able to measure and see change quickly with the right topical skincare coupled with effective in office treatments.?It will give you results and boost confidence so you can start tackling other areas of concern.”

You can still have a simple routine that includes active ingredients — you just don’t want to slather on any product labeled as “anti-aging” without a plan of action. Darden, for example, says her routine has been more or less been the same for years. She keeps her daytime routine simple and adds in a treatment product — like an exfoliator or retinol —?at night. And if you prefer to steer clear of potentially irritating ingredients, that’s fine too. Mistry uses retinol sparingly (every few months), and exfoliates even less. Instead, her method is rooted in protecting the skin from sun damage and pigmentation, coupled with daily facial massage to lift and tighten.

Whichever approach you choose, staying consistent is crucial to seeing results.

Don’t be afraid of beauty tools

From red light masks to microcurrent devices, investing in some beauty tech can be well worth it in the long run — especially if your goal is to lift and firm your skin. No longer only for the spa or derm’s office, these exeprt-approved treatments deliver noticeable results with consistent at-home use. Consider them a high-maintenance step that’ll help you stay low maintenance for years to come (Petersen says it’s a myth that a surgical facelift is the only option for reversing signs of aging).

“In 2024, there are so many amazing non-invasive devices and lasers on the market that can turn back the clock on aging and make you look and feel your best,” Peterson says. “I love having a yearly maintenance plan of devices and lasers?and a solid at-home care routine that I rotate,” she notes of her own routine.
