Sensitive/redness-prone skin needs
Many buyers specifically sought a sunscreen that wouldn't irritate reactive, rosacea-prone, or redness-prone skin, and purchased based on the product's 'soothing' branding.
Repurchase/brand loyalty
A large share of reviewers state this is their 3rd, 4th, or even 6th+ repurchase, and many say they trust the Dr.G brand from other product lines (cream, serum).
1+1 bundle value/promotions
Numerous reviews mention buying specifically because of the 1+1 special set or a sale price, viewing it as a great deal for two full-size tubes.
Acne-prone skin compatibility
Buyers with acne-prone or oily skin purchased after hearing that unlike other sunscreens, this one reportedly does not cause breakouts.
Word of mouth / community recommendation
Several reviewers mention purchasing after reading reviews or hearing recommendations from friends, family, or online communities before trying it themselves.
