Cons	−0.05% retinol is mild — experienced retinoid users may want stronger −fragrance-free but the sodium ascorbyl phosphate has a slight scent −ampoule format with dropper can over-dispense −newer to the international market (limited reviews relative to bigger K-brands)	−Smaller brand recognition −Minimalist approach may not suit active-seekers −Subtle scent from plant extracts
Verdict	APLB's three-vitamin ampoule — retinol, vitamin C derivative, and vitamin E in a stable evening serum at the brand's signature 'A plus B' synergy positioning. The retinol is encapsulated for stability; the vitamin C is the gentler sodium ascorbyl phosphate form (compatible with retinol on the same night, which the L-ascorbic version isn't); the vitamin E provides antioxidant cushion. Excellent value for K-beauty starter retinol — 0.05% is mild enough for new users, the formulation is barrier-supportive, and the price point ($34) makes it easy to commit to consistent evening use.	iUNIK signature product and one of the best-kept secrets in sensitive-skin K-beauty. 70% beta-glucan — a powerhouse humectant and soothing agent — combined with a minimalist supporting cast. The result is a serum that hydrates like hyaluronic acid but also calms reactive skin the way centella does. Cult favorite for a reason.
