Tretinoin (Retin-A) is usually prescribed as a skin cream to treat acne or reduce wrinkles and is not as concentrated as other retinoids. However, you may still want to avoid taking a vitamin A supplement while using Retin-A.

vitamin A tretinoin
Using vitamin A together with tretinoin is generally not recommended. Combining these medications may increase the risk of hypervitaminosis A, a condition that stems from excessive vitamin A-related effects.
Retinol is naturally derived from vitamin A, while tretinoin is a synthetic form. Tretinoin is significantly stronger than retinol. Tretinoin requires a prescription, while retinol compounds are typically over the counter. Typical skin shedding during early use of retinol is less pronounced than tretinoin.
Avoid other topical retinoids, and skin care products containing retinol, with tretinoin. You may also want to avoid salicylic acid, glycolic acid, and erythromycin gel (Erthygel), as these ingredients and products can cause dryness.
What cancels out tretinoin? The effectiveness of tretinoin can be reduced by sun exposure as tretinoin is photosensitive, which means it degrades in daylight.
Retinoids have been implicated in causing mild-to-moderate elevations in routine liver tests, but these elevations are usually asymptomatic and transient, resolving spontaneously even with continued therapy.
Using Tretinoin Correctly
The best time to use Tretinoin is at night. This is because light can degrade Tretinoin and make it less effective. Even more importantly, your skin regenerates the most at night and so your skills will get the maximum benefits from Tretinoin when it is applied during this period.
Retinol is actually just another word for vitamin A. It is an extremely effective cell-communicating ingredient, meaning the substance can literally attach itself to almost every skin cell and it 'tells' the cells that they should behave like healthy, younger skin cells. Retinol is an antioxidant.

In addition, vitamin A can regulate skin tone and reduce the red, purple and brown colouring that acne can leave on the skin. It can also reduce the size and productivity of your oil glands, meaning that your skin produces less acne-causing oil.
Tretinoin (a form of vitamin A) is usually absorbed between 1-2% from facial application on healthy skin. That means about 0.00025 - 0.0005% of your tretinoin could potentially be absorbed into the body. Tretinoin is a perfectly safe topical treatment, so just because it's absorbed doesn't mean it's bad!
Dr Kiran acknowledges some evidence that suggests tretinoin may aid in hair growth: Tretinoin promotes cell turnover, which can help rejuvenate hair follicles. It may enhance the absorption of other hair growth treatments, such as minoxidil.
Retinoid Toxicity
Do not administer tretinoin with vitamin A due to symptoms of syndrome of hypervitaminosis A. Pseudotumor cerebri/intracranial hypertension may also occur, especially if given in combination with other medications that increase intracranial hypertension.
Topical tretinoin can cause your skin to become dry, red, swollen, blistered, or flaky. It may also cause your skin to itch, be painful, or feel like it is burning. Stop using topical tretinoin and call your healthcare provider if these symptoms become worse or do not go away.

The tretinoin in Retin A cream is very prone to break down by exposure to light. UVA breaks down tretinoin the most but the peak wavelength that does this is 420nm, which is just into the visible light spectrum right outside of the UVA wavelength spectrum.
“The symptoms related to tretinoin purging typically involve acne breakouts, severe skin dryness and peeling, redness and irritation, but it is important to know that this phase is temporary and once it's over, the skin will generally begin to improve, and you will be able to see the positive effects.
Vitamin B3 or Niacinamide is a common choice for compounding with Tretinoin due to its skin brightening and pore tightening properties.
