By the end of this post, you'll have a clear understanding of how to incorporate these ingredients effectively into your regimen.

Let’s embark on this journey together, illuminating the path to radiant skin!

Understanding Niacinamide and Lactic Acid

What is Niacinamide?

Niacinamide, also known as nicotinamide, is a form of Vitamin B3 that plays a crucial role in maintaining healthy skin. It has garnered attention for its multifaceted benefits, including:

  • Moisture Retention: Niacinamide helps enhance the skin's barrier function, allowing it to retain moisture more effectively.
  • Minimizing Pores: By regulating sebum production, niacinamide can help reduce the appearance of large pores.
  • Brightening Effects: This ingredient is renowned for its ability to improve skin tone and texture, effectively reducing the appearance of dark spots and hyperpigmentation.
  • Anti-Aging Benefits: Niacinamide has powerful antioxidant properties that combat oxidative stress, helping to reduce the appearance of fine lines and wrinkles.

At Moon and Skin, our Stem Cell C Serum incorporates niacinamide, offering your skin a multifaceted approach to brightness and hydration.

What is Lactic Acid?

Lactic acid, an alpha hydroxy acid (AHA), is derived from fermented dairy products and plays a vital role as a gentle exfoliant. It is particularly known for:

  • Exfoliation: Lactic acid effectively breaks down the bonds between dead skin cells, promoting their sloughing off and revealing fresher, healthier skin underneath.
  • Hydration: Unlike many exfoliants that can be drying, lactic acid is also a humectant, meaning it helps draw moisture into the skin.
  • Smoothing Texture: Regular use of lactic acid can help improve rough skin texture, leaving the skin feeling soft and supple.

Our Hyaluronic Brightening Moisturizer pairs beautifully with lactic acid, enhancing hydration and brightness for a healthy glow.

Why Combine Niacinamide and Lactic Acid?

Both niacinamide and lactic acid are celebrated for their skin-friendly properties. When used together, they can complement each other effectively to enhance overall skin health. Their shared benefits—like promoting a brighter complexion and improving skin texture—make them a dynamic duo in your skincare arsenal.

However, the order of application matters significantly. Understanding the correct timing and the pH levels of these ingredients is essential for maximizing their effectiveness.

The Science Behind Their Application Order

pH Levels and Absorption

The efficacy of skincare ingredients is often influenced by their pH levels. Niacinamide has a relatively higher pH (around 6.0), while lactic acid operates at a lower pH (between 3.5 and 4.0). When applied together without a proper time buffer, the higher pH of niacinamide can neutralize the exfoliating benefits of lactic acid, preventing both ingredients from working effectively.

Recommended Order of Application

To ensure that both ingredients perform optimally, we recommend using lactic acid first, followed by niacinamide:

  1. Cleanse: Start with a clean canvas using a gentle cleanser. Our Superfood Cleanser can be a great option here, as it nourishes while it cleanses.
  2. Apply Lactic Acid: Use a lactic acid product (like a toner or serum) and allow it to sit for about 15 minutes. This waiting period lets the acid work its magic by exfoliating the skin effectively.
  3. Apply Niacinamide: After the 15-minute wait, apply niacinamide. This allows it to penetrate without interference, ensuring its benefits are maximized.

Why This Order Works

Starting with lactic acid allows it to exfoliate the skin effectively, while niacinamide follows to restore hydration and balance. This sequence not only protects your skin’s natural barrier but also helps prevent irritation that might occur if the two were layered too closely together.

How to Incorporate Niacinamide and Lactic Acid into Your Routine

Morning Routine

  1. Cleanse: Use a gentle cleanser to prepare your skin.
  2. Lactic Acid: If you prefer using lactic acid in the morning, consider a lower concentration to avoid sensitivity to sunlight. Allow it to absorb for 15 minutes.
  3. Niacinamide: Apply your niacinamide serum or moisturizer next.
  4. Moisturize: Follow with our Hyaluronic Brightening Moisturizer for added hydration.
  5. Sunscreen: Finish with sunscreen to protect your fresh, exfoliated skin from UV damage.

Evening Routine

  1. Cleanse: Start with a thorough cleanse to remove the day's impurities.
  2. Lactic Acid: Apply your lactic acid product and let it sit for 15 minutes.
  3. Niacinamide: Follow up with niacinamide to soothe and hydrate the skin overnight.
  4. Moisturize: Apply a nourishing night cream or your choice of moisturizer to lock in hydration.

By following these steps, you can harness the full potential of both niacinamide and lactic acid, leading to healthier, more radiant skin.

Key Takeaways

  • Niacinamide and lactic acid can work effectively together when applied in the correct order.
  • Use lactic acid first due to its lower pH, allowing it to exfoliate and prepare the skin.
  • Follow with niacinamide to restore hydration and balance, enhancing skin health.
  • Allow a waiting period of at least 15 minutes between applying these ingredients for optimal results.

Common Questions

Can I use niacinamide every day?

Yes, niacinamide is gentle enough for daily use and can be applied both in the morning and evening. Its hydrating properties make it suitable for all skin types.

Is lactic acid safe for sensitive skin?

Lactic acid is one of the gentler AHAs and is generally well-tolerated, even by sensitive skin types. However, we always recommend patch testing any new product before full application.

Should I apply niacinamide before or after retinol?

It’s typically best to apply niacinamide after retinol. This can help mitigate any potential irritation caused by retinol, allowing your skin to benefit from both ingredients.

Can I combine niacinamide with vitamin C?

While niacinamide and vitamin C can be used together, they may counteract each other’s benefits if applied simultaneously. It’s best to use them at different times of the day—vitamin C in the morning and niacinamide in the evening.

What if I experience irritation?

If you notice any irritation when using these products, consider increasing the time between applications or reducing the frequency of use. Always listen to your skin, and consult with a dermatologist if concerns persist.

Conclusion

Incorporating niacinamide and lactic acid into your skincare routine can unlock a world of benefits, enhancing your skin’s health and appearance. Remember, the key lies in the order of application—start with lactic acid, wait a bit, then follow with niacinamide. This thoughtful layering not only optimizes their effectiveness but also ensures your skin remains balanced and hydrated.
