FAQ
Azelaic acid helps with:
- Acne treatment – Reduces bacterial growth and clears clogged pores.
- Rosacea management – Decreases redness and inflammation.
- Hyperpigmentation correction – Fades dark spots and post-inflammatory marks.
- Skin texture improvement – Exfoliates and unclogs pores for a smoother complexion.
- For acne – Both are effective, but Azelaic Acid is gentler and better for sensitive skin.
- For hyperpigmentation – Azelaic Acid reduces redness and dark spots, while retinol increases cell turnover.
- For anti-aging – Retinol is more effective for fine lines and wrinkles, while Azelaic Acid primarily targets redness and pigmentation.
- For sensitive skin – Azelaic Acid is less irritating than retinol, making it a safer option for those prone to redness or rosacea.
AZELASTINE (a ZEL as
Yes, Azelaic Acid is safe for daily use, and it can be applied once or twice a day, depending on skin tolerance. Those with sensitive skin may start with every other day before increasing frequency.
- Strong exfoliants (AHAs, BHAs) – May cause excessive irritation.
- Benzoyl Peroxide – Can increase dryness and irritation.
- Retinol – May lead to over-exfoliation and redness if not introduced gradually.
- Vitamin C (Ascorbic Acid) – Combining both may cause skin sensitivity; best used at different times of the day.
