Hair, skin, and nails supplements promise thicker hair, stronger nails, and healthier-looking skin with just a few capsules a day. So it’s no surprise they’ve become a daily ritual for millions of people.
While these benefits are absolutely possible, results from beauty supplements are more nuanced than most labels suggest. What actually happens when you take a hair, skin, and nails supplement every day depends on three key factors: the ingredients, the dosages, and how well the formula aligns with your unique biology.
For those who are acne-prone or who have sensitive skin, the wrong supplement can actually work against your skin, sometimes undoing months of progress! That’s why it’s important to understand how these supplements work, what to look for, and what to avoid.
This article breaks down the proven benefits of hair, skin, and nails supplements, potential risks to be aware of (including biotin-related acne), and how to choose a formula that won’t clog pores—such as CLEARSTEM's HAIR SKIN NAILS biotin-free supplement, which was formulated specifically for acne-prone skin.
What Are Hair, Skin, and Nails Supplements?
Hair, skin, and nail supplements are formulated to support the strength, structure, and quality of the tissues that make up your hair, skin, and nails. All three rely heavily on structural proteins like keratin and collagen to stay strong, resilient, and healthy-looking, as well as other nutrients to defend against damage.
Rather than working on the surface, beauty supplements can support your appearance from the inside out. They supply key nutrients involved in protein synthesis, connective tissue support, antioxidant protection, and healthy circulation to hair follicles and skin cells. (1)
Most hair, skin, and nails formulas are designed to help:
-
Improve hair strength, thickness, and growth
-
Decrease hair shedding and thinning
-
Reduce nail brittleness and peeling
-
Support skin elasticity, smoothness, and resilience
Key Ingredients in Hair, Skin, and Nails Supplements (And Why CLEARSTEM Skips Biotin)
While the goals of different beauty supplements might be the same, not all types take the same approach or contain the same mix of ingredients.
Traditional formulas tend to focus on forcing growth through high-dose biotin, while newer formulations emphasize quality, strength, and balance of the tissue being produced. This difference is key, especially for people who struggle with acne.
Here's a closer look at the ingredients used in many hair, skin, and nail supplements, along with their pros and cons:
Biotin (Vitamin B7):
Biotin is the most common ingredient in hair, skin, and nails supplements and is often included because it increases keratin production. Keratin can make hair and nails grow faster and appear stronger, which is one of biotin's main advantages.
The issue with biotin is dosage. The recommended daily value of biotin is just 30 mcg, yet many supplements contain 5,000–10,000 mcg or more.
For people who are acne-prone, biotin can surprisingly be an ingredient that causes acne due to excess keratin stimulation. Specifically, biotin contributes to breakouts when taken in high doses because it leads to clogged pores, worsened skin texture, and can even trigger cystic acne, in some cases. (2)
MSM (Sulfur):
MSM provides bioavailable sulfur, which is a mineral needed for collagen and keratin structure. Rather than overstimulating keratin production (like high doses of biotin), MSM improves the strength and flexibility of hair, skin, and nails. (3)
Another benefit of MSM is that it supports detoxification pathways and helps calm inflammation. This means MSM helps defend against some of the biggest contributors to both acne and hair shedding.
Nettle Root:
This mineral-rich botanical is used to support hair thickness and volume. Nettle root helps reduce excess shedding by supporting healthy hair follicles and scalp circulation, which can promote a fuller, stronger-looking head of hair over time. (4)
Methylated Folate:
Methylated folate is a highly bioavailable form of folate that supports healthy cell turnover and protein synthesis, both of which are needed for hair growth and nail strength. Because it’s methylated, it’s easier for the body to absorb and use efficiently, including for those with absorption challenges. (5)
Vitamin E:
Vitamin E is a fat-soluble antioxidant that helps protect skin and hair from oxidative stress caused by environmental exposure. It also supports moisture retention and barrier health, contributing to softer, smoother, more radiant-looking skin.
Other Common Ingredients in the Beauty Supplement Market:
Many hair supplements—including some that help combat breakouts—also include:
-
Zinc for immune support, wound healing, and oil balance
-
Vitamin C for collagen synthesis support and antioxidant defenses
-
Vitamin A for antioxidant support and anti-aging effects
-
Silica to support connective tissue integrity and collagen synthesis
-
Iron or iodine (sometimes unnecessarily, but usually added to help with thyroid support or to address deficiencies)
On their own, these nutrients can help maintain healthy hair, skin, and nails. So the problem isn't what's included in many beauty supplements, but how these formulas are built.
Most traditional beauty supplements lean heavily on mega-doses of biotin as the main “hero” ingredient, while treating everything else as an afterthought. But this approach ignores some of the most important drivers of real beauty results: inflammation control, nutrient delivery to the follicle, collagen quality, hormonal balance, and acne safety.
For those who are acne-prone, especially, this creates a major issue: you can be supporting hair and nails on paper while simultaneously triggering clogged pores, cystic breakouts, or skin texture problems in real life.
That's why a truly effective hair, skin, and nails supplement should strengthen beauty structures without overstimulating keratin production or disrupting the systems that keep skin clear—hence why we created HAIR SKIN NAILS.
Proven Benefits of Hair, Skin, and Nails Supplements
For most people, hair, skin, and nail supplements can deliver cumulative benefits over time when taken consistently.
Benefits like:
-
Hair that looks healthier and shinier
-
Visibly thicker, stronger-looking hair
-
Reduced hair breakage and shedding
-
New baby hairs along the hairline
-
A fuller ponytail over time
-
Stronger nails with less peeling
-
Less nail brittleness and breakage
-
Improved skin elasticity and firmness
-
Smoother skin texture
-
Increased confidence in their overall appearance
Many users notice nail improvements first, followed by hair strength and texture, and then longer-term improvements in hair density, skin elasticity, and overall skin health. And since CLEARSTEM's HAIR SKIN NAILS is biotin-free, it's beneficial even for acne-prone skin.
How Long It Usually Takes to See Results
Hair, skin, and nails regenerate slowly, so results take time and consistency.
Typical timelines look like this:
-
2–4 weeks: Nails feel stronger and peel less
-
6–8 weeks: Hair texture improves, and breakage decreases
-
3 months: Baby hairs begin to appear
-
4–6 months: Thicker ponytail becomes more noticeable and improved hairline density
As you can see, some patience is necessary to see the full benefits. Overall, daily use and consistency matter more than high doses—since these supplements support biological processes that take time to show their effects.
Possible Side Effects and Risks
The most common side effect reported with hair, skin, and nail supplements is acne, particularly from formulas that include high doses of biotin.
Many are not aware of this and find it to be surprising that their skin's appearance ironically gets worse instead of better after taking high-dose biotin beauty supplements. (6)
Biotin-related acne can occur because:
-
Excess keratin clogs pores
-
Biotin competes with vitamin B5, which the skin relies on for clarity
-
Congestion becomes buried under rapidly turning-over skin
-
For some, cystic breakouts on the face, jawline, chest, back, and even thighs
Other potential issues with some beauty supplements are that they can cause digestive upset or nutrient imbalances when formulas are poorly dosed or unnecessary ingredients are included.
Low or no-biotin formulas dramatically reduce these risks, which is precisely why CLEARSTEM's HAIR SKIN NAILS supplement is biotin-free.
Who Should Avoid Daily Use of Hair, Skin, Nail Supplements?
Beauty supplements, especially some hair supplements, might not be appropriate for everyone due to their high levels of certain nutrients. You should consult a healthcare provider if you:
-
Are pregnant or breastfeeding
-
Have kidney disease or metabolic disorders
-
Experience sudden or unexplained hair loss
-
Have autoimmune or thyroid conditions
For example, hair loss caused by hormonal or autoimmune issues often requires other treatments, such as medications or even time to allow hormones to reset, rather than supplements alone.
Interactions With Medications or Health Conditions
High doses of biotin are known to interfere with lab test results, including thyroid panels and cardiac markers. This can potentially lead to misdiagnosis, which is another reason biotin-free formulas are usually safer for long-term daily use (particularly if you have a condition that requires regular testing).
If you are on medications affecting hormones, nutrient absorption, or metabolism, any supplements you're taking should be reviewed with a provider to err on the safe side.
When to Stop or Talk to a Healthcare Provider
Most people tolerate biotin-free beauty supplements extremely well when taken consistently and as directed. But some might be sensitive to certain ingredients without realizng it. Stop using these supplements and consult your provider if you experience:
-
Worsening cystic acne
-
Digestive discomfort that persists
-
Sudden or patchy hair loss
Do You Need Daily Supplements If You Eat Well?
Even with a "balanced diet," it can be hard to eat the exact amount of nutrients you need for healthy hair, skin, and nails. It's also difficult to consistently obtain minerals like silica and sulfur in needed amounts, considering they aren't found in many foods.
On top of the challenges of eating well, stress, environmental toxins, inflammation, and hormonal shifts can all affect hair and skin quality. Supplements help fill these gaps and support structural integrity over time.
That said, beauty supplements work best alongside a nutrient-dense, gut-healing diet (that's usually low glycemic and excludes foods that cause acne), not as a replacement for one. (7) You'll likely see the best results when you eat a diet with plenty of protein and antioxidants and take supplements consistently for at least several months, too.
