Does Retinol Absorb Into The Bloodstream?

When applied to the skin, a small amount of retinol is absorbed into the bloodstream, with the quantity varying based on the product's concentration, its ingredients, and skin condition. Two primary concerns include:

Birth Defects:

While oral retinoids are known to cause birth defects, the amount absorbed from topical retinol is significantly less. Nonetheless, due to its absorption into the bloodstream, it's advised to avoid its use during pregnancy or breastfeeding.

Vitamin A Toxicity:

Vitamin A toxicity primarily results from ingesting high amounts of vitamin A from food or supplements over time. However, the risk increases when using strong topical retinols. Therefore, I recommend to use a retinol with a low strength of 0.1-0.3% to achieve the same benefits with fewer side effects.
