In this comprehensive review, we’ll explore everything you need to know about this serum, from its ingredients and benefits to real user experiences and application tips. If you’re considering incorporating niacinamide into your skincare routine, read on to determine whether this product is worth your investment.
What Is The Ordinary Niacinamide Serum?
The Ordinary Niacinamide Serum is a skincare treatment that contains 10% niacinamide and 1% zinc, designed to address blemishes, oiliness, and uneven skin tone. Niacinamide, a form of vitamin B3, is known for its multiple skin benefits, while zinc helps to regulate oil production and reduce inflammation. This lightweight, water-based formula is suitable for all skin types, particularly those with acne-prone or oily skin.
Key Ingredients and Their Benefits
1. Niacinamide (10%)
- Regulates oil production: Helps control sebum levels, reducing excess shine and minimizing breakouts.
- Brightens skin tone: Inhibits melanin transfer, helping to fade dark spots and hyperpigmentation.
- Strengthens the skin barrier: Enhances ceramide production to improve hydration and reduce sensitivity.
- Reduces fine lines and wrinkles: Stimulates collagen production for a youthful appearance.
- Calms redness and irritation: Soothes inflamed skin, making it ideal for those with rosacea or sensitivity.
2. Zinc PCA (1%)
- Regulates sebum: Controls oil production to prevent clogged pores and acne.
- Anti-inflammatory properties: Reduces redness and irritation associated with breakouts.
- Supports wound healing: Aids in repairing damaged skin and reducing scarring.
Who Should Use The Ordinary Niacinamide Serum?
This serum is suitable for a wide range of skin types, but it is particularly beneficial for:
- Oily and acne-prone skin: Helps regulate sebum and prevent breakouts.
- Combination skin: Balances oil production without over-drying.
- Dull or uneven skin tone: Improves brightness and reduces dark spots.
- Sensitive skin: Soothes irritation and reinforces the skin barrier.
- Aging skin: Reduces fine lines and supports collagen production.
However, individuals with very dry skin or those using strong exfoliants like retinoids and AHAs may need to introduce it slowly to avoid irritation.
How to Use The Ordinary Niacinamide Serum
To get the most out of this serum, follow these steps:
Step 1: Cleanse Your Skin
Start with a gentle cleanser to remove dirt, oil, and makeup. Pat your face dry before applying the serum.
Step 2: Apply a Few Drops of Serum
Dispense 2-3 drops onto your fingertips and gently press it into your skin. Focus on problem areas such as the T-zone or areas with pigmentation.
Step 3: Follow with a Moisturizer
Since niacinamide can be slightly drying for some people, using a hydrating moisturizer helps maintain moisture balance.
Step 4: Apply Sunscreen (Morning Routine)
If using in the morning, always finish with an SPF 30+ sunscreen to protect your skin from UV damage.
Best Practices:
- Use it once or twice daily. Most people can tolerate niacinamide both morning and night.
- Avoid mixing with vitamin C (ascorbic acid). While niacinamide is generally stable, using it simultaneously with highly acidic products may reduce efficacy.
- Introduce slowly if you have sensitive skin. Start with every other day before increasing to daily use.
