Using Azelaic Acid and Tretinoin Together
Azelaic acid and tretinoin are two topical ingredients commonly used to treat various skin concerns like acne, rosacea, and signs of aging. Both options work well on their own, but can they be mixed together safely?
What is Azelaic Acid?
Azelaic acid is a naturally occurring acid found in wheat, rye, and barley. It is anti-inflammatory, antibacterial, and helps treat a number of skin issues including:
- Mild to moderate acne
- Post-acne marks and scars
- Rosacea (type 2)
- Pigmentation and melasma
It works by killing acne-causing bacteria, reducing inflammation, and blocking melanin production. Azelaic acid products are available over-the-counter in strengths up to 10%. Higher prescription-only 20% creams also exist.
What is Tretinoin?
Tretinoin, also known as retinoic acid, is a prescription derivative of Vitamin A. It is considered the gold standard retinoid treatment for:
- Acne
- Fine lines and wrinkles
- Skin texture and firmness
- Skin discoloration
Tretinoin speeds up cell turnover to unclog pores and boost collagen. It comes as a topical cream, gel, or liquid in strengths ranging from 0.025% up to 1%.
Benefits of Using Azelaic Acid and Tretinoin Together
Combining these ingredients leverages their complementary effects for enhanced outcomes.
Improved Acne Treatment
Using azelaic acid with tretinoin fights acne in multiple ways:
- Azelaic acid kills acne bacteria and reduces inflammation
- Tretinoin speeds up cell turnover and unclogs pores
- The combination targets all major acne causes
Those struggling to control breakouts with a single treatment may see better improvement using both actives.
Fading Post-Acne Marks and Scars
In tandem, these compounds address multiple factors behind post-acne marks including:
- Azelaic acid fades pigmentation and evens tone
- Tretinoin smoothes skin texture and builds collagen
- Together they decrease the appearance of marks
Dual therapy leads to better, longer lasting clearance of old acne scars and discoloration.
Enhanced Anti-Aging Effects
The ingredients also have complementary anti-aging perks:
- Azelaic acid neutralizes skin-aging free radicals
- Tretinoin promotes collagen synthesis and healthy cell turnover
- Using both enhances tone, firmness and elasticity better than either alone
The combination therapy delays and softens fine lines, wrinkles and sagging skin.
Using Azelaic Acid and Tretinoin Together
Alternate Nights
When starting out with azelaic acid and tretinoin, use one active each evening rather than combining them. Allow your skin to adjust to each ingredient before layering both at the same time.
Time Application Correctly
Apply azelaic acid first since it has a thicker, moisturizing texture. Allow it to fully absorb for 5-10 minutes before following with the thinner tretinoin product. Doing so prevents pilling or mixing on the skin.
Start Slowly
Using too much too soon increases irritation when combining actives. Begin by alternating azelaic acid and tretinoin 2-3 nights a week. Slowly work up to applying one right after the other once nightly.
Follow Proper Routine Order
In a full routine, use thinner serums first before topping with thicker creams. Finish with moisturizer to counter dryness and peeling from the strong actives. An example sequence would be:
- Gentle face wash
- Toner to balance pH
- Tretinoin
- 5-10 minute wait
- Azelaic acid
- Light moisturizer
Side Effects and Precautions
Increased Irritation and Dryness
Combining ingredients does ramp up risk for redness, flaking, stinging and sensitivity. Using less of each product and moisturizing diligently helps manage irritation.
Extra Sun Sensitivity
Both azelaic acid and tretinoin make skin more vulnerable to UV damage. Practicing safe sun protocols is critical when using these together - that means seeking shade, wearing protective hats/clothes outdoors and applying broad spectrum SPF 30+ sunscreen daily.
Safety During Pregnancy/Breastfeeding Unclear
The safety of using both actives during pregnancy or breastfeeding is uncertain. Check with your dermatologist first if you are expecting or nursing.
While these ingredients are very complementary, combining them does require some added precautions. Working with a dermatologist ensures you use thisadvanced regimen correctly and safely manage any potential side effects.
The Bottom Line
Azelaic acid and tretinoin are two of the most effective topical skin therapies available. Using them together leverages their combined ability to unclog pores, fade pigmentation, smooth texture and build collagen.
By layering azelaic acid over tretinoin at alternate times, patients see better outcomes treating acne, rosacea, melasma, fine lines, and post-inflammatory skin changes. Following best practices for application timing, order of products and managing irritation allows you to safely harness the Beauty benefits of this super-charged skincare duo.
