Ingredient breakdown
INGREDIENTSNiacinamide (Vitamin B3) ~5-8%Proven
The star ingredient and second listed on the INCI, indicating a high concentration. Niacinamide is one of the most well-researched skincare actives, known for its multitasking abilities across multiple skin concerns.
- Pore Reduction: Studies show 5% niacinamide can visibly reduce pore size and improve skin texture after 12 weeks of use.
- Barrier Support: Boosts ceramide and fatty acid production in the skin, strengthening the natural moisture barrier.
- Anti-Aging: Stimulates collagen synthesis and inhibits glycation, helping reduce fine lines and improve skin elasticity.
- Brightening: Inhibits melanosome transfer to reduce dark spots and even out skin tone over time.
- Oil Regulation: At concentrations of 4-6%, niacinamide helps regulate sebum production and reduce acne breakouts.
Zinc PCA ~3-4%Promising
A zinc salt combined with PCA (pyrrolidone carboxylic acid), a natural humectant found in the skin. This compound delivers the antibacterial and sebum-regulating benefits of zinc along with hydration.
- Sebum Control: Zinc PCA has been shown to reduce excess oil production, helping keep shine under control throughout the day.
- Anti-Inflammatory: Zinc helps calm redness and irritation associated with acne and breakouts.
- Antibacterial: Can reduce the presence of acne-causing bacteria on the skin surface.
- Humectant: The PCA component attracts water to the skin, providing lightweight hydration.
Cannabis Sativa Seed Oil (Hemp Seed Oil) ~1-2%Promising
A plant-derived oil rich in linoleic acid, omega-3, and omega-6 fatty acids. Hemp seed oil is valued for its moisturizing and barrier-strengthening properties without the heavy feel of thicker oils.
- Linoleic Acid Rich: High in linoleic acid, which helps strengthen the skin barrier and soften the upper skin layer.
- Non-Comedogenic: Rated 0 on the comedogenic scale despite being an oil, making it suitable for most skin types.
- Anti-Inflammatory: Omega fatty acids help soothe irritation and reduce redness.
Aloe Barbadensis Leaf Juice ~3-5%Proven
Third ingredient on the list, providing soothing and hydrating benefits. Aloe vera is packed with vitamins A, C, and E, plus natural polysaccharides that bind moisture to the skin.
- Soothing: Known for its anti-inflammatory and wound-healing properties, making it ideal for calming irritated skin.
- Hydrating: Contains monosaccharides and polysaccharides that attract and retain moisture in the skin.
- Antioxidant: Vitamins A, C, and E provide antioxidant defense against free radical damage.
Glycerin ~1.5-2.5%Proven
One of the most effective and well-researched humectants in skincare. Glycerin is naturally present in the skin and draws water from the environment and deeper skin layers to keep the surface hydrated.
- Humectant: Attracts and retains moisture in the upper skin layer for lasting hydration.
- Barrier Support: Helps maintain the skin's natural protective barrier function.

How to use
HOW TO USECleanse Your Face
Start with a clean canvas. Wash your face with your preferred cleanser and pat dry gently with a clean towel.
Apply Toner (Optional)
If you use a toner or essence, apply it first and let it absorb for about 30 seconds before proceeding.
Dispense the Serum
Pump a small amount (2-3 drops) of serum onto your fingertips. A little goes a long way with this concentrated formula.
Apply to Face
Gently press and pat the serum onto your entire face, focusing on areas of concern such as enlarged pores, dark spots, and fine lines. Avoid pulling or rubbing the skin.
Follow with Moisturizer & SPF
Allow the serum to absorb for 1-2 minutes, then apply your moisturizer. In the morning, always finish with sunscreen (SPF 30+).

Skin type compatibility
SKIN TYPESOutstanding choice. Niacinamide and zinc PCA work together to regulate sebum and control shine. Lightweight gel absorbs instantly without adding greasiness.
Balances oily T-zone while providing enough hydration for drier areas. Non-greasy formula adapts well across different facial zones.
Niacinamide and zinc PCA help reduce breakouts and calm inflammation. Low comedogenic rating (1/5). Not suitable for fungal acne due to hemp seed oil.
Provides some hydration from glycerin and aloe, but may not be enough on its own. Best paired with a rich moisturizer or hydrating serum underneath.
Fragrance-free, no harsh alcohols, no silicones. Clean ingredient list reduces irritation risk. Patch test recommended as niacinamide can cause mild flushing in rare cases.
Niacinamide supports collagen production and brightens dull skin. For deeper wrinkles, consider pairing with a retinol or peptide treatment for enhanced anti-aging results.

Frequently asked questions
FAQYes. This serum contains no retinoids, salicylic acid, hydroquinone, benzoyl peroxide, or chemical sunscreens — all commonly flagged ingredients during pregnancy. Niacinamide, aloe vera, zinc PCA, glycerin, and hemp seed oil are all considered safe for topical use during pregnancy and breastfeeding. As always, consult your OB-GYN or dermatologist before introducing new skincare products during pregnancy.
No. This serum contains Cannabis Sativa Seed Oil (hemp seed oil), which is a fatty acid-rich plant oil. Fatty acids, particularly oleic acid and other long-chain fatty acids, can feed the malassezia yeast that causes fungal acne. If you are prone to fungal acne, consider a fungal acne-safe niacinamide alternative such as The Ordinary Niacinamide 10% + Zinc 1% or Good Molecules Niacinamide Serum.
Niacinamide is compatible with most active ingredients. It pairs well with retinol (can reduce retinol-related irritation), hyaluronic acid, peptides, and ceramides. For vitamin C (ascorbic acid), it is best to use them in separate routines (niacinamide in AM, vitamin C in PM or vice versa) as combining them can decrease the effectiveness of both. Niacinamide is safe to use alongside AHA and BHA exfoliants and can help soothe the skin after chemical exfoliation.
This serum is best suited for oily, combination, and normal skin types. The lightweight gel texture and oil-regulating ingredients (niacinamide + zinc PCA) make it especially effective for those with excess sebum production. It also works well for sensitive skin due to its fragrance-free, minimal formula. Dry skin types may find it too lightweight on its own and should pair it with a richer moisturizer. It is suitable for all skin tones and ages, particularly those concerned with aging, pores, and uneven skin tone.
Initial improvements in skin hydration and texture can be felt within the first 1-2 weeks of daily use. Oil-balancing effects typically become noticeable around weeks 3-4. For more significant results like pore minimization, reduced dark spots, and fine line improvement, allow 8-12 weeks of consistent daily use. Niacinamide is a gentle active that works gradually, so patience and consistency are key to seeing visible results.
Apply this serum after cleansing and toning, but before moisturizer and sunscreen. The general rule is to apply products from thinnest to thickest consistency. As a lightweight gel serum, it should go on before heavier creams and oils. Use it in your morning routine (as directed by ACURE) or in both AM and PM routines. Always follow with sunscreen during the day.
This serum has a low comedogenic rating of 1 out of 5, meaning it is very unlikely to clog pores for most people. Hemp seed oil, despite being an oil, has a comedogenic rating of 0 and is actually rich in linoleic acid, which can help keep pores clear. Niacinamide itself helps reduce pore size and regulate oil production. However, everyone's skin is different, so if you are extremely sensitive to oils, do a patch test first.
The Period After Opening (PAO) is 12 months. The serum should be used within 12 months of first opening the pump. Store in a cool, dry place away from direct sunlight to maintain the integrity of the niacinamide and other active ingredients. The glass bottle and pump packaging help protect the formula from air exposure and contamination. With daily use, the 30ml bottle typically lasts 6-8 weeks.
Verdict: The ACURE Radically Rejuvenating Niacinamide Serum is a solid, clean-formula niacinamide serum that punches above its weight for the price. Its standout feature is the exceptionally short ingredient list — just 14 ingredients with zero fillers, fragrances, or questionable additives. The proven combination of niacinamide and zinc PCA delivers real benefits for pore size, oil control, and skin tone. It earns points for being pregnancy-safe, vegan, cruelty-free, and widely accessible. The main drawbacks are the small 30ml size, the presence of hemp seed oil (which makes it unsuitable for fungal acne-prone skin), and a lower niacinamide concentration than some competitors. If you value clean ingredients and a minimal formula over maximum potency, this is an excellent choice at a fair price point.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
