If you've spent any time on beauty TikTok lately, you've probably seen it: twenty-three-year-olds documenting their first botox appointments. Dermatologists recommending retinol before you've developed a single wrinkle. Collagen powders marketed to people whose skin is, by every biological measure, still at its peak.
This is prejuvenation — the idea that preventing aging is easier than reversing it, and that the time to start is before you actually need to. It's a genuine philosophy with some real science behind it. It's also one of the most effective marketing frameworks the beauty industry has ever produced.
So what's actually worth doing — and what's worth skipping?

What prejuvenation actually means
Prejuvenation isn't a clinical term. It's a portmanteau — prevention plus rejuvenation — that started appearing in dermatology circles around 2015 and went mainstream when Gen Z began booking aesthetic treatments in their early twenties. The core idea is sound: some signs of aging are easier to prevent than reverse, and certain habits and treatments work better as a head start than as a correction.
The problem is that "prejuvenation" has become a marketing umbrella broad enough to cover everything from SPF (genuinely essential, costs $15) to $800 laser facials (results vary enormously). Understanding which category something falls into is the actual work.
Sunscreen — worth it, no debate
UV exposure is the single biggest driver of visible skin aging — more than genetics, more than diet, more than any other external factor. A broad-spectrum SPF 30+ applied daily is the most evidence-backed anti-aging intervention that exists. If you do nothing else from this article, do this. A solid mineral or chemical SPF runs $10–30/month and outperforms interventions that cost ten times as much.
Retinol — worth it, but start low
Retinol (vitamin A) is one of the few topical ingredients with decades of peer-reviewed research showing it increases cell turnover, stimulates collagen production, and visibly reduces fine lines over time. Most dermatologists recommend introducing a low-concentration retinol (0.025%–0.05%) in your mid-to-late twenties.
The important caveat: more is not better. Starting with a high concentration or using it too frequently causes irritation and sensitivity without additional benefit. Start once or twice a week, at night, with a moisturizer afterward. And wear your SPF — retinol increases sun sensitivity.
You also don't need a $200 retinol. Drugstore options like Differin or The Ordinary's retinol serum contain well-studied concentrations at a fraction of luxury brand prices.

Baby botox — worth it for some, overhyped for most
Here's what's true: botox relaxes the muscles that create dynamic wrinkles — lines that appear when you squint, frown, or raise your eyebrows. The preventive theory is that if those muscles move less, the lines they'd eventually create are slower to form. There is some evidence for this. There are also dermatologists who argue the muscles compensate, and that the preventive benefit is overstated.
What's also true: botox is a neurotoxin that wears off every 3–4 months (adding up to $800–2,400/year to maintain), and the long-term effects of starting in your early twenties are not well-studied because the practice is that new. It's not dangerous at appropriate doses from a qualified professional — but "qualified professional" is doing a lot of work in a market full of med spas with minimal oversight.
Is it worth it? If you're in your late twenties or early thirties and already seeing lines you don't love, and you have budget to maintain it consistently, it may be. If you're 22 with no visible lines booking it because your FYP told you to — you're solving a problem you don't have yet, at significant ongoing cost, because the industry has successfully monetized your fear of your own future face.
Collagen supplements — probably skip
Collagen is a protein. When you consume protein, your digestive system breaks it down into amino acids before it reaches your skin. Whether those amino acids specifically go on to rebuild collagen in your skin — rather than being used elsewhere — is genuinely unclear from the research that exists. Many studies showing benefit are small, short-term, or funded by supplement companies. Independent dermatologists are generally skeptical. Vitamin C (which your body needs to synthesize collagen) and retinol are more evidence-backed for the same goal, at lower cost.
Cost? Benefit? The Reality of Prejuvenation
If you're building a prejuvenation routine on a real budget, here's the honest allocation:
Non-negotiable: broad-spectrum SPF 30+ daily ($10–30/month)Worth adding in your mid-late 20s: low-concentration retinol, introduced slowly ($15–50/month)Worth discussing with a board-certified dermatologist if specific lines bother you: botoxProbably skip: collagen supplements, expensive "anti-aging" serums that contain the same actives as cheaper products, anything sold primarily through before-and-after TikToks
The biggest "prejuvenation" interventions you can make have no price tag: wearing SPF every day, sleeping enough, not smoking, staying hydrated. These outperform most of what's on the shelves — and the research on them is ironclad.
Aging is not a problem to be solved. Prejuvenation, at its best, is about taking care of your skin in your younger decades so you feel comfortable in it for all the decades that follow. Some of those practices are genuinely worth building into your routine. A lot of what gets sold under the prejuvenation umbrella is the beauty industry monetizing your fear of your own face — and knowing the difference is the actual work.
Preventative Skincare In All Your Eras
What is a Good Routine in Your 20’s, 30’s, 40’s and Beyond?

We’ve established some of the big buzzwords that surround the prejuvenation skin care trend, and we’ve started to put ages to some of those products, but now we’re going to dive deeper into what a good routine looks like at each age.
In Your 20s...
The 20’s are an ideal time to establish a solid skincare routine that focuses on prevention. You will want to be using a daily sunscreen of SPF 30 or higher, and may consider using vitamin C serums or niacinamide to combat environmental damage and promote collagen production. The big focus, however, is washing your face daily, as well as consistently moisturizing. This would be a time to consider introducing a low-concentration retinol product to help regulate skin cell turnover and prevent early signs of aging. It is not necessary, however.
If you start to see wrinkles in your late-20’s, then you may consider Botox. Again, this is not a necessary precaution, but something to think about.
In Your 30s...
The skin's natural collagen production begins to decline in the 30’s, and you may start to notice more fine lines, a dull skin tone, or a loss of volume in the cheeks or around the lips.
This would be the time to start using eye creams to address fine lines and maintain the delicate skin around the eyes. You may also utilize hyaluronic acid-based products to maintain skin hydration and plumpness.
Definitely consider a retinol at this point, and start taking collagen supplements to undo some of the natural loss.
In Your 40s + Beyond!
This will probably be past the time of preemptive skincare, but don’t worry! You can consult with a dermatologist about treatments like Botox to address dynamic wrinkles and maintain a youthful appearance.
This will be the age where sun damage is apparent. You may start to see hyperpigmentation, an uneven skin tone, and dryer skin.
Make sure to use a retinol by this point to smoothen wrinkles. Also be sure to drink lots of water for hydration as your metabolism will have begun to slow.
You can also incorporate products with peptides and growth factors to support skin repair and elasticity. These can be found in moisturizers and night creams!
If you have further questions or skincare needs, routine check-ups with a dermatologist can help tailor skincare routines to your evolving skin needs.

Adopting a preventive approach to anti-aging skincare involves understanding the appropriate products and treatments for your age and skin type.
By establishing a consistent routine that includes sun protection, antioxidants, and retinoids, and by considering professional treatments when necessary, you can effectively maintain your skin's health and youthful appearance over time.
However, hydration, exercise, and a balanced diet come just as much into play as Botox and retinols do.
Remember that aging is not a bad thing! Wrinkles are not something you have to get rid of, though if it makes you feel more confident, then by all means do so. Do what feels right for you and what will allow you to feel confident at any age!
