What the gurus are saying
This serum arrives already showing signs of vitamin C oxidizing, and the low 4% concentration means it may not tackle hyperpigmentation as effectively as higher-potency formulas. One expert found it left an oily residue that felt too heavy, especially in warmer months, and questioned whether the price matched the results; however, the gentler strength does lower irritation risk, which may appeal to those with sensitive skin or trouble tolerating other vitamin C serums. Another reviewer praised the formula for acne-prone skin, noting the witch hazel and salicylic acid focus.
