πŸ”¬ Ingredient Breakdown

🧬 Niacinamide (Vitamin B3) 10% Proven

A multi-tasking skincare superstar that improves skin tone, reduces pore appearance, strengthens the moisture barrier, and fights early signs of aging. One of the most well-researched ingredients in skincare.

  • Brightening: Inhibits melanin transfer to reduce dark spots and even skin tone
  • Barrier Support: Increases ceramide production for stronger, healthier skin
  • Oil Control: Helps regulate sebum production without drying
  • Anti-Aging: Shown to reduce fine lines and improve skin elasticity at 4-5% concentration
βœ…
Safe for all skin types including sensitive and acne-prone. Rarely causes irritation even at 10% concentration.

πŸ’§ Sodium Hyaluronate (Hyaluronic Acid) Proven

The sodium salt form of hyaluronic acid, a powerful humectant naturally found in skin. Binds to water molecules to deliver intense hydration and plump the skin.

  • Hydration: Can hold up to 1000x its weight in water
  • Penetration: Smaller molecular size allows better skin absorption
  • Plumping: Temporarily fills fine lines for smoother-looking skin

🌿 Glycerin Proven

A time-tested humectant that draws moisture into the skin and helps maintain the lipid barrier. Non-comedogenic and suitable for all skin types.

  • Moisturizing: Effective from 3% concentration, with increasing benefits at higher levels
  • Barrier Repair: Keeps skin lipids in optimal state for healthy barrier function

πŸ”¬ Acetyl Glucosamine Promising

An amino sugar that serves as a precursor to hyaluronic acid production and works synergistically with niacinamide to improve hyperpigmentation.

  • Brightening: Combined with niacinamide, shown to fade brown spots after 8 weeks of use
  • Gentle Exfoliation: Promotes healthy cell turnover

❓ Frequently Asked Questions

Yes! Niacinamide (Vitamin B3) is one of the safest skincare ingredients for pregnancy and breastfeeding. It's FDA-approved and recommended by dermatologists for expecting and nursing mothers. This serum contains no retinoids, salicylic acid, hydroquinone, or other pregnancy-contraindicated ingredients. However, always consult your healthcare provider before starting any new skincare product during pregnancy.

Yes, this serum is fungal acne safe. The formula is free from common malassezia triggers like fatty acids, oils, esters, polysorbates, and fermented ingredients. It has been verified safe on fungal acne databases like SkinSort. The lightweight, oil-free formula won't feed the yeast that causes fungal acne.

Yes! Niacinamide is highly compatible with most active ingredients. It pairs well with retinol (can reduce irritation), AHAs/BHAs (supports skin barrier), and even vitamin C (though some prefer to use them at different times of day). For sensitive skin, introduce one new active at a time and monitor for any reactions.

This serum works well for all skin types but is particularly excellent for oily, combination, and acne-prone skin. The lightweight, non-greasy formula absorbs quickly without adding shine. It's also great for sensitive skin due to its fragrance-free, hypoallergenic formula. Those with very dry skin may want to layer a richer moisturizer on top.

You'll notice improved hydration immediately. Texture improvements typically appear within 2-4 weeks of consistent use. For visible brightening and dark spot reduction, expect 6-8 weeks of twice-daily application. Pore refinement and long-term benefits become more noticeable after 8-12 weeks. Consistency is key!

Apply after cleansing and toning, but before heavier serums, moisturizers, and sunscreen. The general rule is thinnest to thickest consistency. Use twice daily (morning and evening). In the AM, always follow with SPF 30+. At night, you can layer retinol or other treatments after this serum has absorbed.

No, this serum is non-comedogenic with a comedogenic rating of 0-1 out of 5. The oil-free, lightweight formula is designed specifically to not clog pores. In fact, niacinamide can help minimize pore appearance and regulate sebum production, making it beneficial for those prone to clogged pores and breakouts.

The serum has a PAO (Period After Opening) of 12 months. Niacinamide is a stable ingredient that doesn't oxidize or degrade quickly like vitamin C. Store in a cool, dry place away from direct sunlight. The glass bottle with dropper helps protect the formula from contamination and light exposure.

β˜…β˜…β˜…β˜…β˜†
4.5 out of 5

Verdict: Neutrogena Hydro Boost+ Niacinamide Serum is an excellent drugstore option for those seeking a straightforward, effective niacinamide treatment. With its clinically-proven 10% niacinamide concentration, hyaluronic acid, and gentle fragrance-free formula, it delivers real results for uneven skin tone, enlarged pores, and dull complexion. The pregnancy-safe and fungal acne-safe formulation makes it accessible to a wide range of users. While the 1 oz bottle may seem small for the price, the quality ingredients and dermatologist-recommended status justify the investment. Best suited for oily, combination, and acne-prone skin types looking for a reliable, no-fuss brightening serum.

lightbulb What are Notable Effects & Ingredients?

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 Β«promisesΒ» 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.

question
lightbulb What is the Ingredient Safety Breakdown?

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.

muscle Pro Tip Alert!

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.
