They always say that these products are known to "build collagen" but then you hear that it "thins the skin" so whats with that paradox  |

| retinoids thin the epidermis (outer layer of the skin), as the skin flakes a lot while using them, but they are supposed to thick the dermis, thus to build collagen there. |

| The collagen building comes from the epidermal layers (underneath) but the outer layer thins as Aiva mentioned. |

| So you ultimately end up with thicker skin overall, but more sensititive to sun since the epidermis is thinner. |

| The thinning of the epidermis (outermost layer) may be why some people think that their pigmentation has worsened when they are on retin A. But actually, it's the thinner epidermis making the pigment more obvious. As long as you're wearing an effective sunscreen during the day, the skin shouldn't actually get darker. The sunscreen is very very important. People shouldn't use retin A or retinols without a good sunscreen. |
