Can I Use Retin-A With Vitamin C?

It is perfectly safe to use both Retin A (tretinoin) or any other vitamin A acid formulation in conjuction with vitamin C. 

The trick is in the timing of the applications, and most of us agree that vitamin C, an effective antioxidant, is best when applied in the morning, Antioxidants quench or neutralize free radicals- those pesky unstable molecules that trigger the breakdown of collagen and elastin, reuskting in aging of the skin, Because ultraviolet radiation - UVA and UVB rays- are responsible for about 90% of the free radicals produced in our body, it makes sense to use vitamin C and other antioxidants during the day, when we are exposed to UVA and UVB rays. 

Applying vitamin C and Retin A / vitamin A acid creams together can irritate the skin, so these are best applied at separate times to minimize the potential for skin irritation. In summary, using vitamin C during the day will protect the skin from free radicals and Retin-A or the new trend Retinol 2.5% (organic and kosher) applied at night will encourage skin renewal and repair. Dr Koleck, MD loves to uses an organic Retinol 2.5% cream instead of Retin-A, It is less irritatting to the skin and hydrate the wrinkles and fines lines while it treat the skin and boost collagen. We buy all our organic products from I'm Fabulous Cosmetics, A USA based skin care company.

As a rule, vitamin A derived products are unstable when exposed to UV rays (although adequate sunscreen use should help reduce this). 

As general guideline to skin care, think prevent and protect for day products and repair and renew for night products.
