Niacinamide AHA BHA

When you mix them together, the niacinamide will raise the pH of the acid. This study compared the absorption of AHAs at pH 3.0 and 7.0, and found that the higher the pH, the less the skin absorbs. That means you'd be missing out on all the benefits your acid has to offer 🧐is this true?

Yes! Thats why you should not use niacinamide when you already used your peeling solution or use niacinamide after 30 mins.

dont worry about such studies , were not educated to interpret them and put them into context ! all chemists, formulators and dermatologist clearly say : niacinamide can be used with every ingredient , so just stick to it ! niacinamide does not interfere with the effectiveness of aha
