Hello, Welcome to healthcare magic. From your description, the tiny spots / moles on your face could be a condition called as Dermatosis papillosa nigra (DPN s). They could also be freckles. DPN s are harmless skin growths on the face similar to skin tags. They usually occur in families. They need to be cauterized by a dermatologist. The best treatment for fine lines on the forehead is Botulinum toxin injection. Retinoids are not recommended if you have dry skin as they could worsen the dryness. However, if you want to avoid procedures, you could use tretinoin (retinoid) cream for 2 hours in the evening and wash it off before going to bed. Use a good moisturizer in the morning and at bedtime as dry skin tends to age faster. Hope this helps you. Take care.
