Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Tretinoin is the best retinoid due to its proven skin benefits. It only available with a prescription in many countries.
All forms of OTC retinoids goes through a conversion line until it can become effective. The final step of conversion is retinoic acid; retinoic acid IS Tretinoin.
This is why tretinoin is so effective; it gets to work immediately on the skin.
Research on tretinoin has found it to be incredibly effective for reducing the signs of aging. It helps improve damage from the sun, even the skin tone, and smooth out wrinkles. It is also an effective acne treatment by reducing and balancing out sebum production in pores.
Tretinoin, like other forms of Vitamin A, increases the turnover cycle of skin cells. This helps the skin create newer and healthier skin cells faster.
It can cause irritation, redness, and dry skin because it is considered a "strong" ingredient. Those with sensitive skin should consult a professional about using tretinoin.
Using retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.

Azelaic acid is a naturally occurring acid that is derived from grains. However, the lab-created form is typically used within cosmetic products as it has better shelf-stability.
It has been shown to be effective in the treatment of acne, rosacea, and other skin conditions. Azelaic acid helps reduce the growth of bacteria that cause acne and helps to reduce inflammation.
It also helps to improve the appearance of skin by reducing the production of sebum and unclogging pores.
Azelaic Acid also has antioxidant properties. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.
One of the main benefits of azelaic acid is that it is gentle and well-tolerated by most people. It is also non-comedogenic, meaning that it will not clog pores.
