Wonderful Shampoo! Elastine Honey Avocado 2X Protein Shampoo

I'm so happy I found this in Michigan, USA and it's the best shampoo I ever used! Elastine Honey Avocado 2X Protein Shampoo. It lathers thick when washing and makes my long hair so nice. I love this product!

Love acacia

I have been searching for a true acacia perfume which is hard to come by in the states. This perfume smells the closest to acacia which is a nostalgic smell for me. Doesn’t last very long on me though.

This product is really nice! I've been worried about dryness and skin elasticity lately, but there's no stickiness, and I love how firm it feels after applying it.

Mucin Collagen Volumizing Cream Ampoule 4ml x 5

I like that I can see improvement in my skin. I've been using it for about a month and a half, and I can see subtle effects. I think using it continuously will add more glow! It helps improve the skin barrier and gives an amazing shine. I recommend using it with the Minari duo — it applies even better, haha.

Mucin Collagen Volumizing Cream Ampoule 4ml x 5

First of all, when you apply it, it gives a glow and doesn't feel dry. Also, it isn't greasy or sticky! I'm using it in my nighttime skincare routine. I use all of ClearDea's products, and they're definitely good — it seems to really help with barrier care, so I'll keep using it.
