Can sun exposure of uv index 1 induce wrinkles after retinol and AHA use?

Question

Last month, I used retinol .05% and lactic acid 10% each once a week, on different days. On several occasions, I went out the next morning or day during a UV Index 1 day without sunscreen. Sometimes, I used an SPF 15 lotion, but I have read that these do not have coverage like sunscreen does. I have noticed new wrinkles under my eyes. Previously I only had very fine, and few, lines. Now there are many and my eyes look quite wrinkled. Can just these exposures induce these problems, so quickly?

No, it is not possible for that exposure to have that large of an impact so suddenly. It is very important to wear an spf of at least 30 on a daily basis, no matter the weather. Especially when using a retinol or any other exfoliating products. If these are new products you're using, you could be experiencing Transepidermal Water Loss, which is basically water loss in your skin. Make sure you're using a proper moisturizer. The wrinkles could also be caused by dehydration, diet, lack of sleep, crying, allergies, alcohol consumption or Botox wearing off.
