An excellent product for ageing skin

This is an excellent product for ageing skin & i bought it for my mum who is loving it very much. As the percentage of retinol is not quite clear i was dreading to use it directly on my face so i just mixed it with my regular moisturiser & could see a bit of a difference in the slight pigmentation that I have around my mouth area. As my mum has mature & ageing skin i thought this product would more suitable for her than me so i just gave it to her & so far she has not faced any issues with this product. According to her, her skin feels firmer, tighter & plumper & these Retinol Drops are helping her in clearing out her hyperpigmentation as well. Giving it a 5 stars rating as per her experience.
