I may be able to help as I have used her other lines like you did. I ordered the entire Botanical line when it came out. I need to say, however, that I also use Dr. Denese products, so Principal Secret is not my only skin care line. Her cleanser, however, has been the only one I've used for years.
Botanical Cleanser - love it. This line of products feels "heartier" than the Reclaim line. I doubt I can define it better, but it feels like a more powerful, yet GENTLE, cleanser than the Reclaim version.
Botanical Day Cream - love it. Same feeling as above. Seems a tad thicker than the Reclaim version, but not heavier and absorbs quickly. Again, I'd say heartier.
Botanical Night Cream - It was fine, but I use Dr. Denese at night.
Botanical Eye Serum - This was the only product that I could not use. It stung a little bit. If she offered an eye cream in this line, I would try it.
Botanical serums - Not as hydrating as Dr. Denese, BUT I tried these in fall & winter. Maybe they would be fine for summer, but I don't plan to purchase again.
I hope this helps.
