I’m a 36-year-old skincare junkie, and Ole Henriksen Truth Serum ($49, 1oz) transformed my dull, sensitive skin.
This vitamin C-packed serum promises brighter, firmer skin, and after months of use, I’m sold.
Its lightweight formula fights wrinkles and hydrates deeply.
Grab it at Sephora or Ulta to boost your glow.
I’ll share my experience, pros, cons, and tips, plus compare it to other serums, to help you decide if it’s your holy grail.
Let’s uncover why Truth Serum is a must-have.
My Experience with Ole Henriksen Truth Serum

My sensitive skin was looking tired and uneven, so I tried Ole Henriksen Truth Serum (15ml, $24) after getting a sample.
The citrusy scent woke me up, and the weightless, orange-tinted serum sank in fast.
I used one pump nightly, followed by a light moisturizer, and woke up to smoother, brighter skin.
After two weeks, fine lines around my eyes softened, and my complexion glowed, earning compliments from friends.
In Denver’s dry air, it kept my skin hydrated without irritation, a rare win for my reactive skin.
The small bottle lasted six weeks, as a little goes a long way.
I tried daytime use, but sunscreen felt greasy over it, so nights worked best.
By week four, my skin felt firmer, with less redness.
You’ll love the instant glow, but sensitive skin needs a patch test first.
It’s become my nightly staple, and I’m hooked on the results.
What Makes Ole Henriksen Truth Serum Stand Out
Truth Serum is a vitamin C powerhouse with 15% vitamin C + E Ferulic Acid to brighten and firm skin.
Its collagen-boosting formula includes moisture-binding ingredients like sodium hyaluronate and aloe juice, plus antioxidants to fight environmental damage.
The lightweight, non-greasy texture suits all skin types, especially sensitive ones, with calming extracts.
Unlike heavy serums, it absorbs instantly, making it ideal under moisturizer or makeup.
You’ll notice its citrusy scent and fast results, setting it apart in the vitamin C game.
How It Fits Into My Routine?
I apply Truth Serum every night after cleansing, using one pump to cover my face and neck.
It pairs perfectly with a lightweight moisturizer like Ole’s Sheer Transformation for a dewy finish.
In the morning, I skip it to avoid greasiness under sunscreen.
For special events, I use it for an instant glow before makeup.
You’ll find it easy to add to your nighttime routine, especially if you want brighter, smoother skin without irritation.

I store my Truth Serum in a cool bathroom drawer to keep it potent, as heat can degrade vitamin C.
Cleaning the pump weekly stops clogs, which happened once.
One pump at night covers my face, and I follow with Ole’s moisturizer for a dewy glow.
I patch-tested first, avoiding irritation on my sensitive skin.
Using it within six months keeps it fresh, and I skip layering with retinol to prevent stinging.

Comparison with Other Vitamin C Serums
- Ole Henriksen Truth Serum Vs. SkinCeuticals C E Ferulic

SkinCeuticals C E Ferulic ($182, 1oz) is a gold-standard serum with 15% L-ascorbic acid, vitamin E, and ferulic acid.
I tried it for a month, and it brightened my skin, but the sticky texture felt heavy compared to Truth Serum’s lightness.
It reduced redness well, but the price was a shock.
My sensitive skin tolerated it, though it stung slightly.
You’ll pick SkinCeuticals for clinical-grade results, but Truth Serum’s affordability and comfort make it my daily choice.
- Ole Henriksen Truth Serum Vs. Drunk Elephant C-Firma Fresh

Drunk Elephant C-Firma Fresh ($78, 1oz) mixes 15% vitamin C with pumpkin ferment and pomegranate enzymes.
I used it daily, and it brightened my skin, but the thicker texture pilled under makeup.
It lasted longer than Truth Serum’s 0.5oz bottle but irritated my sensitive skin slightly.
You’ll choose Drunk Elephant for its potent formula, but Truth Serum’s calming ingredients and lighter feel suit sensitive skin better.
- Ole Henriksen Truth Serum Vs. The Ordinary Vitamin C Suspension 23%
The Ordinary Vitamin C Suspension 23% ($7, 1oz) is a budget-friendly, high-potency option.
I tried it, and it brightened my skin in two weeks, but the gritty texture and strong sting were tough on my sensitive skin.
It lacked Truth Serum’s hydrating ingredients, feeling drying.
You’ll grab The Ordinary for its price, but Truth Serum’s smoother application and calming extracts make it worth the extra cost.
- Ole Henriksen Truth Serum Vs. Glow Recipe Pineapple-C Serum
Glow Recipe Pineapple-C Serum ($49, 1oz) blends vitamin C with pineapple enzymes and chamomile.
I loved its juicy scent and lightweight feel, but it took three weeks to see brightening, slower than Truth Serum.
It hydrated well but didn’t firm as much.
You’ll pick Glow Recipe for a fun, gentle formula, but Truth Serum’s faster results and anti-aging benefits edge it out.
- Ole Henriksen Truth Serum Vs. Vichy LiftActiv Vitamin C
Vichy LiftActiv Vitamin C ($28.50, 0.34oz) uses 15% vitamin C and hyaluronic acid.
I found it hydrating, but the small bottle lasted only three weeks, and results were less dramatic than Truth Serum.
It felt slightly sticky and stung my skin once.
You’ll choose Vichy for a quick hydration boost, but Truth Serum’s longer-lasting bottle and firming effects make it a better investment.
Performance Across Use Cases
Truth Serum shines for nightly use, brightening and firming my skin in a week.
It’s perfect for sensitive skin needing a glow without irritation.
For daytime, it’s less ideal under sunscreen, feeling greasy.
I used it before events for a radiant base under makeup, earning compliments.
You’ll love it for anti-aging and dullness, but pair with a strong moisturizer in dry climates for extra hydration.
Ingredient Quality and Safety

Truth Serum’s 15% vitamin C (ascorbic acid) brightens, with vitamin E and ferulic acid boosting stability.
Green tea, aloe, and sodium hyaluronate calm and hydrate, ideal for sensitive skin.
It’s vegan, cruelty-free, and free of parabens, but fragrance (limonene, linalool) may irritate some.
I had no reactions, but a patch test is wise.
You’ll feel safe using it, though sensitive skin should start with every-other-day application.
Ease of Use and Application
The pump bottle makes Truth Serum easy to dispense—one pump covers my face.
Its lightweight texture absorbs in seconds, perfect for layering under moisturizer.
The 0.5oz travel size lasted six weeks, but the pump clogged once, needing a quick wipe.
You’ll find it fuss-free for nightly use, but clean the pump regularly and store it properly to maintain potency.
Who Should Use Truth Serum
Truth Serum’s ideal for anyone with dull, sensitive skin or early signs of aging.
It suits those wanting brighter, firmer skin without heavy textures.
If you use strong actives like retinol, introduce it slowly to avoid irritation.
You’ll love it if you crave a glowy, even complexion, but test first if you’re prone to fragrance sensitivity.
Safety and Precautions
Patch test Truth Serum on your inner arm, as the fragrance caused mild tingling once for me.
Store it in a cool, dark place to prevent oxidation.
Avoid layering with acids to prevent stinging.
I skipped retinol on Truth Serum nights to stay irritation-free.
You’ll want to start with every-other-day use if your skin’s extra sensitive.
