Overview
Squalane and vitamin C anchor the Brenner SQAC1, a 1 fl oz facial oil serum aimed at brightening and firming skin while moisturizing.
Despite being labeled a serum, its item form is listed as oil, so it applies and absorbs like a facial oil rather than a watery or gel serum. Squalane is included for a moisturizing, non greasy feel while vitamin C is the named active for brightening. It's scented with rose, worth noting for anyone sensitive to fragrance in a leave on product.
- Squalane and vitamin C facial oil serum
- 1 fl oz size
- Rose scented
- Cruelty free, natural formula
Who it's for
Suits people wanting an oil based brightening and firming serum with a rose scent. Not ideal for anyone who prefers unscented actives or wants a lightweight water based vitamin C serum.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines squalane and vitamin C in one formula
- Cruelty free and made with natural ingredients
- Aimed at brightening and firming
- Rose scent may not suit fragrance sensitive users
- Oil format layers differently than typical water based serums
Performance notes
Squalane is typically used to mimic skin's natural oils and support a moisturizing, non greasy finish, while vitamin C is included for its role in brightening tone. Being an oil rather than a water based serum affects how it layers, generally best applied after lighter, water based products.
