In brief
- A viral trend has tweens and young teens layering ten or more products, including strong actives, onto skin that is still developing.
- Young skin’s stratum corneum (the outermost barrier layer) does not reach adult-level thickness and function until roughly age 4-6, and its needs keep changing right through puberty.
- A 2025 peer-reviewed study of top TikTok teen skincare videos found an average of 11 (up to 21) potentially irritating actives per routine, and allergens in the majority of videos studied.
- Dermatologists and paediatric guidance agree: retinol, AHAs, BHAs and peptides are not appropriate for pre-teen or early-teen skin.
- Before puberty, a child’s facial skin has broadly similar, simple needs to the rest of their body: hydration and protection, not correction.
- The kindest, most evidence-led routine for a child or young teen is a gentle cleanser, a light fragrance-free moisturiser, and daily SPF. Nothing more.

Wenn Sie in letzter Zeit auch nur ein wenig Zeit in den sozialen Medien verbracht oder durch die Morgennachrichten gescrollt haben, ist Ihnen wahrscheinlich ein ziemlich alarmierender Trend aufgefallen. Tausende von Tweens und jungen Teenagern filmen sich dabei, wie sie aufwendige Morgen- und Abendroutinen durchführen und zehn oder mehr verschiedene Hautpflegeprodukte auf ihr Gesicht auftragen.
At the Beauty Trade Special in Utrecht, this was a genuine talking point among parents and professionals alike. Children are asking for high-strength anti-ageing serums, exfoliating acids and complex actives before they have even finished primary school.
That leaves some important questions. Why is this happening? What is the right age to actually start a skincare routine? And why does young skin need to be left alone to “grow and harden” naturally? Let us skip the marketing hype and look at the biology.
The science of growing skin: the immature barrier
To understand why a ten-step routine is so unsuited to a tween or young teen, it helps to look at how the skin barrier actually develops.
When people talk about skin needing to “grow and harden”, they are really talking about the maturation of the stratum corneum, the outermost layer of the skin that acts as its protective shield. Research following children from birth shows this layer keeps changing for years: stratum corneum thickness, water loss through the skin (TEWL), and lipid organisation do not reach adult-comparable levels until roughly four to six years of age. In the earliest years, the stratum corneum is measurably thinner, its cells are smaller, and cell turnover is faster than in adult skin.
Puberty adds another layer of change. Studies looking at the skin barrier of children approaching puberty found that while facial (cheek) barrier function is often good in the pre-teen years, it tends to shift as hormonal changes begin, alongside the well-known rise in sebum (oil) production. In other words, young skin is not a smaller, less-finished version of adult skin that simply needs “boosting” with adult products. It is on its own developmental timeline, with different needs at different stages.
What happens with a “10-step routine”?
When a tween or young teen introduces a routine filled with high-percentage niacinamide, salicylic acid (BHA), glycolic acid (AHA) or vitamin C, they are not supporting their skin. They are interrupting a system that, biologically, is already doing its job well.
Piling on strong acids and high-concentration actives can strip away the skin’s still-developing lipids. Rather than allowing the barrier to mature at its own pace, this kind of overload is linked to irritation, dryness and micro-damage to the surface. A 2025 peer-reviewed study in Pediatrics analysed the top TikTok skincare videos aimed at children and teens and found the top 25 videos featured an average of 11, and up to 21, potentially irritating active ingredients, most commonly citric acid, along with retinol derivatives and vitamin C. Nineteen of those 25 videos contained at least one recognised contact allergen, most often fragrance. Dermatology and paediatric guidance both flag retinol, AHAs, BHAs and peptides specifically as inappropriate for developing skin, precisely because of this irritation and sensitisation risk.
The illusion of the “separate face line”
Family skincare used to be simple: one gentle, good-quality lotion for the whole body, face included. Today, marketing has convinced many parents that even young children need a dedicated, separate “facial routine”.
Biologically, this is largely a marketing construct rather than a skin necessity. Before puberty, a child’s facial skin has broadly similar, simple needs to the skin on their arms or legs: hydration and protection, not correction. Children do not produce meaningfully elevated sebum on the face before their hormones shift at puberty, so a single, fragrance-free, dermatologically-tested moisturiser is generally considered appropriate for the face as well as the body at this stage. Much of the “kids’ facial care” category is built on getting children into consumer habits early, rather than responding to an actual skin need.
The right age vs. the right ingredients
Dermatologists broadly agree that skincare can start young, but what counts as appropriate “skincare” changes completely depending on how mature the barrier is. Here is a simple, sourced breakdown of what skin actually needs at each stage.
| Stage | What the skin needs | What to avoid |
|---|---|---|
| Early childhood (roughly under 6) | Barrier still maturing. A simple, fragrance-free moisturiser for face and body, plus SPF outdoors. | Any active ingredients, fragranced products, adult “anti-ageing” formulas. |
| Pre-teen (roughly 6-12) | Gentle cleanser (if desired), light fragrance-free moisturiser, daily SPF 30+. | Retinol, AHAs, BHAs, peptides, exfoliating scrubs, multi-step “routines”. |
| Early-mid teens (roughly 13-17) | The same simple base, with a gentle, low-percentage salicylic acid (BHA) cleanser as an appropriate, targeted option if genuine acne appears. | High-strength actives, chemical peels, prescription-strength ingredients without medical guidance. |
| 18 and over | An informed adult choice, built up gradually and matched to individual skin needs. | N/A — this is the stage where actives can be introduced thoughtfully. |
We get asked about benzoyl peroxide a lot, because it is a famous, effective acne fighter. But at Junita, we believe in clearing the skin without compromising the skin barrier. Benzoyl peroxide works by introducing oxygen into the pore to kill acne-causing bacteria, and it frequently brings peeling, dryness and redness along with it, a lot for skin that is still developing. That is why, where a targeted step is genuinely needed, we favour salicylic acid instead. It is oil-soluble, so it unclogs pores from the inside out, and at gentle percentages it clears breakouts without stripping away the skin’s natural lipids. It gives clearer skin without asking a teenager’s barrier to pay for it.
Letting nature do its job
Young skin is already working at its biological peak: rapid, healthy cell renewal and an abundance of its own collagen. Introducing anti-ageing or heavily texturising products to a child’s routine is a bit like tuning an engine that is already running perfectly. It does not improve it. It risks breaking it.
At Junita® Lab, our whole philosophy is built on respecting skin’s natural rhythm and supporting the barrier rather than forcing it into compliance. For the young people in our lives, keeping things simple, a basic, gentle moisturiser and a reliable SPF, is one of the kindest, most evidence-backed things we can offer them. It gives their skin the space to grow, harden and protect itself the way it is designed to.
From the Junita range
This particular message is for the young people in your life, and their skin needs simplicity, not our actives. But if you are a parent reading this and thinking about your own skin, barrier-first, evidence-led care matters at every age.

View productWho this approach is for
- Parents wondering whether the viral tween/teen “10-step routine” trend is safe for their child.
- Any young person who has been asking for adult anti-ageing serums, acids or peels.
- Anyone building a first, appropriately simple skincare routine for a child or young teen.
- Teenagers dealing with genuine acne, who need age-appropriate options rather than an adult routine.
How to start, gently
- Keep it to two or three steps. Cleanser, moisturiser, and SPF during the day. That is genuinely enough.
- Choose fragrance-free, simple formulas. Look for “fragrance-free” and “non-comedogenic” on the label, not long ingredient lists.
- Save actives for later. Retinol, AHAs, BHAs and peptides can wait until adulthood, or until a dermatologist recommends them for a specific medical reason.
- Treat teen acne appropriately, not aggressively. A gentle, low-percentage salicylic acid cleanser is a reasonable, age-appropriate option if genuine breakouts appear, without stripping the barrier the way harsher options can.
- Talk about the “why”, not just the “no”. Explaining that skin is still developing tends to land better with a teenager than a flat refusal.
- See a GP, paediatrician or dermatologist for any persistent or severe skin concern in a child or teenager, rather than reaching for stronger products at home.
What we are building at Junita
Junita® exists for skin that needs support, not a fight. That philosophy does not stop at our own customers. It is exactly why we want to see young skin left alone to do what it already does brilliantly: grow, harden and protect itself, at its own pace, on its own timeline.
Key takeaways
- The skin barrier keeps maturing for years after birth and continues changing through puberty.
- A 2025 peer-reviewed study found the most popular teen skincare content online routinely features irritating actives and allergens.
- Retinol, AHAs, BHAs and peptides are not appropriate for pre-teen or early-teen skin.
- Before puberty, facial skin has broadly the same simple needs as the rest of the body.
- A gentle cleanser, light fragrance-free moisturiser and daily SPF is the evidence-backed routine for young skin.
- Save active ingredients for adulthood, or for a specific condition under medical guidance.

Frequently asked questions
What age should a child start a skincare routine?
A very simple routine, a fragrance-free moisturiser and daily SPF, is appropriate from early childhood. What changes with age is not whether skincare exists, but how complex it should be. Actives beyond basic hydration are generally not recommended before adulthood, unless a doctor prescribes them for a specific condition.
Why shouldn’t tweens use retinol or exfoliating acids?
Paediatric and dermatological guidance flags retinol, AHAs and BHAs as inappropriate for developing skin because they can over-dry, irritate and sensitise a barrier that is still maturing. This can lead to redness, breakouts and increased sun sensitivity rather than any benefit.
What does “grow and harden” actually mean?
It refers to the stratum corneum, the skin’s outer barrier layer, reaching adult-comparable thickness, water retention and lipid organisation. Research shows this process continues for years after birth and is still shifting as puberty begins.
Does my child need a separate facial skincare line?
Before puberty, facial skin has broadly similar, simple needs to the rest of the body. A single, gentle, fragrance-free lotion used for the whole body is generally considered appropriate for the face too at this stage.
What ingredients are actually safe for teenage acne?
A gentle, low-percentage salicylic acid (BHA) cleanser is our preferred, age-appropriate option for genuine teen acne. Benzoyl peroxide is a well-known and effective acne treatment too, but it works by oxidising the pore and can leave skin dry, peeling and irritated, a difficult trade-off for a barrier that is still maturing. Salicylic acid clears pores from the inside out without stripping the skin’s natural lipids in the same way. Stronger or prescription-strength treatments should be guided by a GP or dermatologist rather than assembled from social media.
Can a heavy skincare routine actually cause breakouts in teens?
Yes. Overloading young skin with strong actives can damage the barrier, and a damaged barrier is less able to defend against everyday bacteria, which can lead to irritation and breakouts rather than clearer skin.
When can teens start using stronger active ingredients?
The general guidance is to wait until adulthood, around 18, unless a doctor or dermatologist has prescribed something specific for a diagnosed condition such as severe acne.
