OK to use Infadolan over Retin-A?

[nchantrez]

Hi Sarah,

I applied some Infadolan on my face 1 hour AFTER applying 0.05% rx Retin-A. I did that so my face would be moisturized because the Retin-A usually dries me too much.

So can I continue putting Infadolan OVER Retin-A or is there any conflicts with these 2 topicals?

You can use Tretinoin (it contains vit. A) and Infadolan (it contains vit. A and D) at the same time. No need to wait. First apply Tretinoin and then Infadolan.

Fat-soluble vitamins, (D, E, K and A) can be mixed with creams or oils. No need to wait.

  Water-soluble vitamins, (C and B) can't easily penetrate oily surfaces. That is why you should apply vit. C on clean, ointment/cream-free skin, let the skin absorb it and only then apply a cream.
