🔵 Lightweight Moisturizer Well-Suited for Combination and Oily Skin

According to CreamScan analysis, Tarte Rainforest of the Sea Foundation is quite moisturizing, with a moisturizing rating of 4.6 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.3 out of 10 and a high humectancy of 6.9 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%).

This type of moisturizer is well-suited for people with combination and oily skin who want significant hydration in a relatively lightweight, non-greasy formula. It combines a substantial amount of humectants with a limited amount of occlusive to enhance moisturizing efficacy without feeling too heavy.

This product may also be an option for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

💧 A Humectant Enhancement for Any Skincare Routine

But it’s not limited to combination and oily skin - such a humectant enhancement will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.
