The Squalane Secret: Why Nikki Glaser's 15-Year Skincare Staple Is Still the Beauty Industry's Best-Kept Bargain
Introduction
In an era where luxury skincare brands routinely charge $200 for a single ounce of serum, comedian Nikki Glaser has quietly been proving that great skin doesn't require a second mortgage. The outspoken star recently revealed that she's been loyal to one remarkably affordable product for over fifteen years: The Ordinary's 100% Plant-Derived Squalane. While celebrities typically tout exclusive, hard-to-find formulas, Glaser's honesty feels almost radical—and dermatologists aren't surprised. Squalane has quietly become one of the most researched and recommended ingredients in modern skincare, praised for its ability to hydrate without clogging pores, strengthen the skin barrier, and play nicely with nearly every other active ingredient. In 2026, as "skin barrier health" and "minimalist routines" dominate beauty conversations, squalane is having a well-deserved renaissance. This article explores why this unassuming molecule deserves a permanent place on your shelf, how to use it correctly, and which formulas deliver the best results for every skin type.
What Exactly Is Squalane—and Why Does It Matter?
Before we dive into routines and product picks, let's clarify a common point of confusion.
Squalene vs. Squalane: Squalene is a lipid naturally produced by your sebaceous glands (it makes up roughly 12% of your skin's surface oils). Squalane is its stabilized, hydrogenated cousin—created by adding hydrogen molecules to squalene, which makes it far more shelf-stable and less prone to oxidation. In skincare, squalane is the version you'll find in products.
Why Your Skin Loves It
| Benefit | What It Means for Your Skin |
|---|---|
| Mimics natural sebum | Absorbs quickly without a greasy film, making it ideal for all skin types |
| Barrier support | Reinforces the lipid matrix that keeps moisture in and irritants out |
| Non-comedogenic | Unlikely to clog pores—safe for acne-prone skin |
| Antioxidant-friendly | Helps protect against environmental stressors when paired with vitamins |
| Universal compatibility | Layers well under or over retinol, vitamin C, niacinamide, and SPF |
Unlike hyaluronic acid, which draws water into the skin (a humectant), squalane is an emollient—it seals in moisture and smooths the surface. The two aren't competitors; they're teammates. This is why many dermatologists recommend a "humectant + emollient" pairing, especially in dry or cold climates.
The Vegan Shift
Historically, squalane was harvested from shark liver oil—a practice that decimated deep-sea shark populations. Today, the overwhelming majority of squalane on the market is plant-derived, typically from olives, sugarcane, rice bran, or amaranth. This shift has made squalane both ethical and more affordable, which is precisely how a brand like The Ordinary can sell a 30ml bottle for under $15.
The 2026 Squalane Renaissance
If squalane has been around for decades, why is it suddenly everywhere in 2026?
Several converging trends explain the surge:
- The "skin barrier" obsession. After years of over-exfoliation and aggressive acid routines, consumers are pivoting toward repair. Search interest in "barrier repair" has remained elevated since 2024, and squalane sits at the center of that conversation.
- Minimalist, multi-purpose formulas. The "skinimalism" movement favors fewer, harder-working products. Squalane earns its place because a single bottle can function as a serum, a makeup primer, a hair oil, and a body moisturizer.
- Clean beauty's maturation. Rather than chasing exotic new ingredients, 2026 shoppers are returning to proven, single-ingredient heroes with transparent sourcing.
- Celebrity transparency. When figures like Glaser share what they actually use—rather than what they're paid to use—it resonates. Authenticity is the new luxury.
How to Use Squalane: A Step-by-Step Guide
Squalane is forgiving, but placement in your routine matters. Here's the optimal order for most skin types:
The Layering Rule
- Cleanse with a gentle, pH-balanced cleanser.
- Apply water-based treatments first (hydrating toners, essences, hyaluronic acid serums, vitamin C).
- Apply actives (retinol, niacinamide, exfoliating acids)—allow 1–2 minutes to absorb.
- Seal with squalane. Warm 2–4 drops between your palms and press gently into the skin. This locks in everything beneath it.
- Finish with moisturizer and SPF in the morning.
Quick Reference by Skin Type
| Skin Type | Recommended Use | Drops |
|---|---|---|
| Dry / Dehydrated | Layer over moisturizer as a final seal | 4–6 |
| Oily / Acne-prone | Use alone as a lightweight night moisturizer | 2–3 |
| Combination | Apply to dry zones only (cheeks, around eyes) | 2–3 |
| Sensitive / Reactive | Mix with moisturizer to buffer actives | 1–2 |
| Mature | Press into fine lines before bed; consider squalane + retinoid combo | 3–5 |
Beyond the Face
Squalane's versatility is part of its appeal:
- Hair: Run a drop through dry ends to tame frizz and add shine.
- Cuticles and nails: Massage in nightly to prevent peeling.
- Body: Add to your lotion in winter for extra emollience.
- Beard and brow care: Softens coarse hair without residue.
- Makeup prep: A thin layer under foundation creates a smooth, dewy base.
Expert Tips and Recommendations
We spoke to the principles dermatologists and estheticians consistently emphasize when it comes to squalane:
- Pair it with humectants. Squalane seals moisture in—but only if there's moisture to seal. Always layer it over damp skin or a hydrating serum.
- Don't fear it if you're oily. Squalane's molecular structure closely resembles your skin's own oils, so it signals to your sebaceous glands that they don't need to overproduce. Many oily-skin users report less midday shine after adding it.
- Use it to buffer retinol. If you're new to retinoids, apply squalane before your retinol to reduce irritation—a technique dermatologists call the "sandwich method."
- Store it away from direct sunlight. While squalane is more stable than squalene, heat and light degrade any oil over time.
- Patch test new formulas. Even single-ingredient products can contain trace preservatives or carrier oils that irritate sensitive skin.

| Squalane + Peptides | Firming and hydration in one layer |

| Squalane + Vitamin C | Reduces the sting of L-ascorbic acid formulas |

Common Mistakes to Avoid
Even a foolproof ingredient can be misused. Here are the pitfalls we see most often:
- Applying squalane to dry skin. Without moisture beneath it, you're sealing in nothing. Always apply to damp skin or over a hydrating serum.
- Using too much. More isn't better. Two to four drops is plenty for the entire face; excess can feel greasy and waste product.
- Skipping SPF. Squalane supports your barrier, but it is not sun protection. You still need a broad-spectrum SPF every morning.
- Confusing squalane with squalene. Check labels carefully—oxidized squalene can irritate skin, while squalane is stable.
- Expecting overnight miracles. Squalane is a maintenance ingredient, not a treatment. Its benefits compound over weeks, not hours.
- Layering it before water-based products. Oils create a barrier; apply them last in your routine (before SPF) so other products can penetrate.
- Ignoring the source. If ethical sourcing matters to you, look for "plant-derived" or "sugarcane-derived" on the label.
