From childhood to your golden years, your skin changes throughout your life. At Apex Skin, Rachel McKernan, MPAS, PA-C, helps families navigate these changes with expert dermatological care. Whether you’re dealing with diaper rash, teenage acne, or age spots, understanding what’s normal at each stage can help you maintain healthy skin for life.
According to McKernan, healthy skin starts with two essential habits that apply at every age: moisturizing and wearing SPF 30 or higher sunscreen.
“There is no age where applying sunscreen or moisturizer is too young to do,” she emphasized. “As soon as a child can hold a sunscreen, getting them to start applying it themselves is a great idea.”
As we age, our skin transitions from acne-prone stages to drier phases, accumulating sun damage along the way. Because we see ourselves in the mirror daily, we often don’t notice these changes until they’ve progressed. That’s why preventive skincare routines are crucial, and they should start early.
When it comes to necessary concerns, McKernan is clear: changing moles and sun protection should always be on your radar. But unnecessary worries?
“If you have a worry, you should get it addressed,” she said. “You’ll be surprised how many people are not concerned about a mole that is concerning.”
The key is getting professional eyes on your skin regularly. “It is never too early to get a skin mapping of your spots. It is never too early to get a consultation for your acne. And it is never too late to talk about your sun damage.”
What is skin mapping? This process involves documenting all your moles and their locations. Knowing you have a mole is important and it allows you to map its changes. If it disappears, your dermatologist will want to understand why your body is destroying it. If it grows or multiplies, they’ll want to know what is causing a shift.
For babies and children under eight, moisturizer is your best friend. During Ohio winters, when kids want to build snowmen and play outside, their cheeks take a beating. McKernan recommends applying Aquaphor or Vaseline before they head out.
Once the skin barrier breaks down, conditions like atopic dermatitis and other types of eczema can develop, making skin more susceptible to infections and fungus. The solution? Lots of moisturizer. If issues don’t resolve with moisturizer alone, it’s time to see a provider.
There is no minimum age for a child to start seeing a dermatologist. While pediatricians are excellent resources for skin conditions, dermatologists often see some common skin issues in young children:
Around age twelve (though it can happen earlier or later), hormonal acne begins to develop. This is the stage when many young people first develop significant skin concerns.
And while acne is a condition that can be treated, McKernan notes that the acne scarring is harder to treat. Which is why she recommends that even mild acne be addressed because preventing scarring by treating acne is far easier than treating the scars later on.
There’s no age too early to seek professional acne treatment. Over-the-counter products containing salicylic acid and benzoyl peroxide can provide quick fixes, but they’re often not strong enough for long-term results.
Many teens arrive at appointments with their TikTok treatment plan and while McKernan appreciates this initiative, medical-grade products offer higher concentrations and professional guidance on proper use. Some products work twice daily, others once daily, and some only once weekly.
Consistency is key and less is more when it comes to finding the best skincare routine as a teen.
Tips for building the best habits:
A typical teen routine includes:
Young adults often chase skincare trends—some amazing, some questionable.
Snail mucin had its moment, and beef tallow is currently making waves. While some trends have genuine benefits, layering multiple active ingredients without guidance can backfire.
“If you’re doing your snail mucin with your salicylic acid with your hyaluronic acid, you’re probably going to dry out your face,” McKernan warns. “And you’re not really getting down to the root cause of your skincare problems.”
Many young adults approach skincare with anti-aging as their primary goal. While McKernan doesn’t discourage this motivation, she wants to shift the focus to preventing actinic damage.
What is actinic damage? This is the breakdown of skin caused by UVA and UVB rays. Each sunburn kills layers of skin tissue and the peeling you experience is dead skin. When new cells form after this damage, they’re more likely to split abnormally over time, potentially developing into skin cancer.
Protecting your skin from the sun by wearing sunscreen prevents actinic damage and therefore is the best anti-aging method. At this age and beyond, people are eager to be tan in the summer months and McKernan gives some warnings and suggestions.
“Base tans do not provide sun protection,” McKernan warned. “Base tans provide about 1% SPF. We are looking for an SPF of at least 30.”
Instead, if you are hoping to look tan she suggests self-tanners, spray tans, and tanning lotions.
Beyond sunscreen, McKernan emphasized:
As we age into our 40s and 50s, skin laxity becomes more noticeable. This is when we may notice that jowls have started to form and marionette lines (the lines around the mouth) deepen. With hormonal shifts, we see increases and decreases in weight and experience oilier or drier skin that is inconsistent from year to year.
These rapid changes require a treatment plan that changes more frequently to address the challenges showing up. As you begin to recognize the early signs of dry or oily skin, you can adapt your routine accordingly.
Applied every morning, vitamin C helps prevent free radical damage, which works alongside UV protection. McKernan recommends Vitamin C as an oil, not a cream because cream formulations don’t penetrate the skin well enough to be effective.
At this phase in life skin changes more quickly and it becomes critical to see a dermatologist once a year for a full-body skin exam.
While sunscreen remains crucial, dryness becomes a primary concern in later adulthood.
With a more open skin barrier, people experience increased dryness and new sensitivities. Many patients report never being sensitive to ingredients when younger, but developing allergic contact dermatitis or irritant dermatitis as they age.
When rashes develop, people often suspect medications or food allergies. While these can occur, allergic contact dermatitis from skincare products is more common. The culprits are usually:
McKernan recommends switching to gentle options and avoiding heavily fragranced products.
At any age, but especially as we get older, these changes warrant immediate attention:
Remember the ABCDEs of mole changes: Asymmetry, Border irregularity, Color changes, large Diameter, and Evolution (any change over time). That “E” is where awareness comes in. If you feel as if something is changing, get it checked. You’re the one who notices when something evolves.
Some products are universal, others need personalization:
Feel free to share:
Keep individualized:
Several conditions have strong genetic components:
Atopic dermatitis and acne: Both conditions tend to run in families. If a parent needed isotretinoin (Accutane) for acne, their child might need it too.
One factor affects skin health across all life stages: stress. It can cause rashes, trigger acne breakouts, and accelerate wrinkle formation. While managing stress is easier said than done, McKernan recommends finding outlets—whether that’s talking to someone, spending time doing something you love, or engaging in physical activity.
“We will see a lot of skin progression caused by stress,” she shared, making stress management a crucial part of any skincare routine.
From newborns to grandparents, dermatological care is for everyone. Whether you’re dealing with a specific concern or simply want to establish healthy habits, professional guidance makes all the difference.
