Picking your Niacinamide:

Choose products with at least four or five percent concentrations— which has been clinically proven to reduce pigmentation, fine lines and wrinkles, and acne and at five percent was found to improve redness and sallowness.

Things to know when mixing Niacinamide and Lactic Acids:

When you mix them together, the niacinamide will raise the pH of the acid; the higher the pH, the less the skin absorbs and the less effective the products.

Another problem with mixing niacinamide and acid is that it can cause redness and flushing. Not a welcoming outcome when you’re trying to beautify your skin

So how do you properly layer Niacinamide and Lactic acids?

  1. Apply them at different point of the day

Niacinamide is non acidic and can be used with other non acidic serums and lotions with little waiting/ absorption time. Include this water based treatment before oil based serums in the morning when you’re less likely to have time to wait.

When using lactic acids it is usually recommended that you wait 5-30 minutes for the product to absorb into the skin before applying other serums and lotions— maybe this routine will better suit for night time or when you have more time to unwind.

  1. Apply them 30 minutes apart

This way, each product have time to absorb into the skin, give your skin time to return to its normal pH and allow each product to work at its intended pH.

When layering products, start with products with the lower pH (acids), allow 30 minutes and follow with your higher pH serums like niacinamide.

The Ordinary – Niacinamide 10% + Zinc 1%

This is a great beginners Niacinamide that will give you great results for little to no cost. I personally use this twice a day and I find it significantly reduces an inflammation and really help with my breakouts.
