### ⭐⭐⭐⭐⭐ Allergy-prone & combination-skin holy grail!
*by D***. on August 3, 2021*

Very lightweight, no fragrance & gives a glass-skin look (without being overly greasy)! I have acne-prone, combination skin that is often dehydrated, in addition to numerous allergies. I mostly layer this product over moisturizer (applied over my serums/wet skin) as my last step prior to sunscreen. It gives a beautiful, dewy look while preventing transepidermal water loss, and has not caused any breakouts or irritation for me. :)
