If you’ve been battling breakouts for years — trying everything from drugstore benzoyl peroxide to prescription Accutane — you know the drill. Each new product arrives with hope, and each one eventually disappoints. Either it doesn’t work, or it works but destroys your skin barrier in the process.
Clearstem promises something different: skincare that fights acne and aging simultaneously, without pore-clogging ingredients. Founded in 2017 by licensed esthetician Danielle Gronich and integrative health practitioner Kayleigh Christina, the brand has built a cult following. On Thingtesting, it holds a 4.8 out of 5 stars with 100% of reviewers saying they’d recommend it to a friend.
But does it live up to the hype? Let’s break it down.
The Clearstem Philosophy
Clearstem’s core promise is simple: no pore-clogging ingredients, ever. The brand has identified over 450 ingredients that can clog pores and excludes every single one from its formulations. This matters because many anti-aging products contain comedogenic ingredients — which means if you’re over 25 and dealing with both acne and fine lines, most conventional options will make one problem worse while treating the other.
Gronich’s background gives the brand credibility. Before co-founding Clearstem, she ran The San Diego Acne Clinic, where she reportedly achieved a 98% success rate in clearing patients’ skin. Her co-founder Kayleigh Christina brings the nutritional and hormonal health expertise, creating a brand that addresses acne from both outside and inside.
Product Line Overview
Clearstem’s product range covers both topicals and ingestibles:
Topical Skincare:
– CELLRENEW Serum — plant stem cell serum that balances oil and regulates acne
– CLEARITY Serum — mandelic acid + vitamin C exfoliant (nicknamed “blackhead dissolver”)
– BOUNCEBACK Serum — triple-peptide anti-aging serum (fans call it “Botox in a bottle”)
– HYDRAGLOW Moisturizer — bakuchiol + squalane daily moisturizer
– BRIGHTMEUP Toner — gentle exfoliating toner
– YouAreSunshine SPF 50 — tinted mineral sunscreen
Supplements:
– MINDBODYSKIN — hormonal acne supplement with DIM, vitamin B5, turmeric, and ashwagandha ($58/bottle)
What Real Users Are Saying
The CNN Underscored Review
One of the most compelling testimonials comes from CNN Underscored, where a journalist who had struggled with acne for a decade shared her experience. She had tried everything — retinoids, benzoyl peroxide, salicylic acid, even Accutane. Nothing delivered lasting results. After using Clearstem’s Clear Skin Routine, she wrote: “Clearstem is the only skin care that made my acne go away.”
Her before-and-after transformation was dramatic enough that the article became one of CNN Underscored’s most-read beauty reviews.
The New York Post 4-Week Supplement Test
Kendall Cornish from NY Post tested MINDBODYSKIN, Clearstem’s hormonal acne supplement, for four weeks. She’d been dealing with hormonal acne around her jawline and had developed perioral dermatitis from over-treating her skin with harsh topicals.
Within two weeks, her skin was noticeably calmer with no new cystic breakouts. By week four, she reported: “I have never in my life found a product that actually cleared my skin in under a month. It did what years of prescriptions, topicals, birth control, and dietary changes failed to do.”
Her biggest surprise? Her usual pre-menstrual breakout simply never showed up.
Ingredient Deep Dive
What makes Clearstem different is the ingredient philosophy. The “No List” includes parabens, phthalates, synthetic fragrances, SLS/SLES, PEGs, benzoyl peroxide, and over 450 pore-clogging ingredients.
Key active ingredients across their product line:
| Ingredient | Purpose |
|---|---|
| Plant Stem Cells | Regenerative, plumps skin, reduces fine lines |
| Mandelic Acid | Gentle exfoliation, unclogs pores |
| Bakuchiol | Natural retinol alternative (anti-aging without irritation) |
| Squalane | Hydration, barrier support |
| DIM (in supplement) | Balances estrogen/testosterone for hormonal acne |
| Vitamin B5 | Reduces excess oil production |
| Ashwagandha | Lowers cortisol (stress-induced breakouts) |
The Skeptical Take
No review is complete without addressing the criticisms. The Filtery published an investigation (updated March 2026) noting a few concerns:
- Petrochemical claims: Despite stating they avoid “petrochemicals,” some ingredients like Nylon-12 and butylene glycol are petroleum-derived
- Phenoxyethanol: Used as a preservative; it’s a controversial ingredient that some clean beauty advocates avoid
- Plastic packaging: No refillable options currently available
- Price point: At $58 per bottle for the supplement and $40–90 for serums, it’s a significant investment
- Supplement claims controversy: Dermatology Times has questioned the marketing that compares MINDBODYSKIN to Accutane without head-to-head clinical studies
Clinical Data
Clearstem cites clinical trial results:
– 100% of participants experienced improved skin barrier function instantly
– 100% saw smoother skin in 4 weeks
– 96% saw a healthier complexion
– 92% saw clearer skin
– 75% saw significant acne reduction using topicals alone
Who Is Clearstem For?
Clearstem is best suited for:
– People with hormonal acne (jawline, chin breakouts)
– Those with sensitive skin that can’t tolerate harsh actives
– Anyone who’s failed traditional treatments like Accutane or prescription topicals
– People who want anti-aging benefits without pore-clogging ingredients
It may NOT be ideal for:
– Those on a tight budget (it’s premium-priced)
– People expecting overnight results (most users see changes in 4-6 weeks)
– Those who prefer minimal routines (Clearstem works best as a system)
The Bottom Line
Clearstem delivers on its core promise: effective acne treatment that doesn’t compromise your skin barrier. The brand’s unique position — addressing both acne and aging — fills a genuine gap in the market. Real user testimonials from major publications like CNN and NY Post add credibility that’s rare in the skincare space.
The price is high, and the ingredient philosophy isn’t 100% squeaky-clean despite the “non-toxic” positioning. But for the right person — someone with stubborn hormonal acne who’s tired of harsh treatments — Clearstem could be genuinely life-changing. As one reviewer put it: “Discovering Clearstem and the founders genuinely changed my life.”
