What is Niacinamide?
Niacinamide is a form of vitamin B3 that is gaining popularity in skincare regimens. It's scientifically proven to address multiple signs of aging and damage for many different skin types.
Some key benefits of niacinamide include:
- Minimizing the appearance of enlarged pores
- Reducing uneven skin tone and hyperpigmentation
- Combating acne and breakouts
- Improving skin elasticity and firmness
- Protecting against environmental damage
- Softening fine lines and wrinkles
Niacinamide is gentle, non-irritating, and safe for all skin types. It's especially beneficial for oily, acne-prone skin. The optimal daily concentration is 2-5%. You can find it as an active ingredient in many serums, creams, and essences.
Other Key Facts
- Also known as nicotinamide
- Water-soluble, so plays nicely with other ingredients
- Research-backed with minimal side effects
- Can be used morning and/or night after cleansing
What is Glycolic Acid?
Glycolic acid is an alpha hydroxy acid (AHA) derived from sugar cane. It's arguably the most popular AHA in skincare for its powerful exfoliating effects.
Glycolic acid benefits include:
- Exfoliating dead skin cells
- Reducing acne breakouts
- Improving skin texture and tone
- Minimizing fine lines and wrinkles
- Brightening hyperpigmentation
- Unclogging pores and preventing blackheads
It's ideal for those struggling with lackluster, congested skin and signs of photodamage. Concentrations typically range from 5% to 20% in leave-on products.
Other Key Facts
- Derived from sugar cane
- Belongs to the AHA family
- Can cause irritation if overused
- Best for experienced acid users
Niacinamide vs. Glycolic Acid: How Are They Different?
While both ingredients offer skin-improving benefits, there are some key differences between niacinamide and glycolic acid:
Exfoliation
Glycolic acid is an AHA exfoliator that dissolves the bonds between dead skin cells to reveal fresh new skin. Niacinamide does not exfoliate the skin.
Skin Types
Glycolic acid may cause sensitivity and irritation, especially in those with dry or sensitive skin. Niacinamide is gentle enough for all skin types.
Usage
Glycolic acid is ideally used 2-3 times per week at most. Niacinamide can be used twice daily without adverse effects.
Side Effects
Overuse of glycolic acid can result in redness, peeling, burning, and skin damage. Niacinamide rarely causes side effects when used properly.
Photosensitivity
As an AHA, glycolic acid increases photosensitivity to UV rays. Niacinamide offers some protection against sun damage.
Benefits Comparison
Here is a closer look at how the benefits of niacinamide and glycolic acid stack up against each other:
Fine Lines and Wrinkles
Glycolic acid promotes faster cell turnover and collagen production to reduce fine lines. Niacinamide improves elasticity and supports the skin barrier for a plumping effect.
Uneven Skin Tone
Both ingredients excel at brightening discoloration and hyperpigmentation. Glycolic acid accelerates cell renewal while niacinamide blocks melanin production.
Enlarged Pores
Glycolic acid deeply cleanses pores but can be drying. Niacinamide tightens pores by improving elasticity and regulating oil production.
Acne
Glycolic acid cleans out congested pores and has antimicrobial effects. Niacinamide controls excess sebum, balances skin, and reduces inflammation.
Skin Texture
Glycolic acid deeply exfoliates rough, uneven texture. Niacinamide refines skin with continued use but is not an exfoliant.
How to Use Niacinamide and Glycolic Acid Together
When used properly, niacinamide and glycolic acid can complement each other nicely. Here are some tips for using them together:
- Use niacinamide twice daily and glycolic acid 1-2 times weekly at most.
- Apply niacinamide after water-based serums and before creams.
- Use glycolic acid at night and always follow with moisturizer.
- Opt for a lower glycolic acid percentage around 5%.
- Pay attention to any increased redness or irritation.
- Always wear sunscreen the morning after using glycolic acid.
Another option is to alternate nights using one ingredient vs the other if your skin can tolerate it. Introduce new actives slowly and build up frequency based on your skin's feedback.
The Verdict: Niacinamide vs Glycolic Acid
In the battle of niacinamide vs glycolic acid, there is no universally superior ingredient. The "winner" depends on your unique skin goals and concerns.
For most skin types, niacinamide is the gentler, more beginner-friendly option. Glycolic acid is best for experienced acid users targeting significant exfoliation.
Those with sensitive or dry skin may not tolerate daily glycolic acid use. Combination and oily skin sees excellent results from both actives.
Ultimately, the two ingredients pair exceptionally well for a balanced skincare regimen. Niacinamide strengthens and soothes skin daily, while glycolic acid provides a weekly exfoliating boost.
FAQs
Can I use niacinamide and glycolic acid together?
Yes, you can use both ingredients together safely by alternating nights or using niacinamide twice daily and glycolic acid 1-2 times weekly.
Which is better: niacinamide or glycolic acid?
There is no definitively "better" ingredient. Niacinamide is gentler and ideal for daily use, while glycolic provides stronger exfoliation 1-2 times weekly.
What percentage of glycolic acid should I start with?
Start with a 5% glycolic acid product 1-2 times per week if you are new to AHAs. Slowly increase to 8-10% based on your skin's tolerance.
Can people with sensitive skin use glycolic acid?
Glycolic acid may cause irritation, redness, and sensitivity in some. Test carefully and discontinue use if any discomfort occurs.
When should I apply niacinamide in my routine?
Apply niacinamide serum after water-based products and before heavier creams. It can be used morning and night.
