Cosrx Full Fit Propolis Synergy Toner and Cosrx BHA Blackhead Power Liquid Review

K-beauty brand COSRX has long been praised for affordable, effective skincare rooted in science and simplicity. Today, we’re diving deep into two of their bestselling products: the Full Fit Propolis Synergy Toner and the BHA Blackhead Power Liquid.

Price: Propolis toner (INR 835), BHA liquid (INR 900), prices vary as usual

🧴 COSRX Full Fit Propolis Synergy Toner (150 ml)

🌼 What It Is:

A nutrient-rich toner-essence hybrid formulated with propolis extract and honey to deeply hydrate, soothe, and promote radiant skin.

📦 Key Highlights:

• Propolis Extract (72.6%): Anti-inflammatory, antioxidant-rich, promotes wound healing; great for acne prone skin

• Honey Extract (10%): Hydrating and mildly antibacterial.

• Panthenol + Hyaluronic Acid: Calms and plumps the skin barrier.

• Minimal formulation: Just 11 ingredients — ideal for sensitive skin.

💧 Texture & Feel:

• Lightweight but with a viscous essence-like feel.

• Applies smoothly and absorbs quickly, though can feel tacky if over-applied.

✅ Pros:

• Deeply hydrating — great for dry, dehydrated, or sensitized skin.

• Reduces redness and irritation

• Gives skin a plump, glassy GLOW, for real

• Layers well with other products (serums, SPF, makeup)

❌ Cons:

• Can feel sticky if overused

• Not vegan (contains bee products)

• May feel too heavy for very oily skin, specially in summers

Rating: 3.9/5

An outstanding toner for dry, sensitive, or normal skin — especially in colder seasons or drier climates.

🧴 COSRX BHA Blackhead Power Liquid (100 ml)

🌼 What It Is:

A gentle but effective chemical exfoliant with 4% Betaine Salicylate (a milder form of BHA) that clears out pores, smooths texture, and targets blackheads and whiteheads.

📦 Key Highlights:

• Betaine Salicylate (4%): A gentler BHA derivative that exfoliates inside pores without excessive dryness.

• Willow Bark Water: Natural BHA source with soothing benefits.

• Niacinamide: Brightens skin and helps with post-acne marks.

• Sodium Hyaluronate: Offsets potential dryness.

💧 Texture & Feel:

• Lightweight, non-sticky, serum-like, but has a light oily consistency

• Absorbs quickly, fragrance-free, non-irritating for most users.

✅ Pros:

• Targets clogged pores, blackheads, and rough texture

• Gentler than salicylic acid

• Can improve acne scars and tone over time

• Well-suited to oily, combo, or acne-prone skin

❌ Cons:

• Can cause purging (temporary breakouts in the first 2–3 weeks), might be harsh on sensitive skin, specially in hot humid months

• Drying if overused — start 2–3x per week

• Requires sunscreen daily due to increased sun sensitivity

Rating: 3/5

One of the most accessible and well-balanced BHA products on the market. Best for oily, acne-prone, or textured skin looking for a gentle introduction to chemical exfoliation.

💬 Final Verdict: Worth It?

Both the toners are good in their own way, as they serve two different purposes. Personally speaking, for my sensitive skin, BHA liquid was a little hard to tolerate. I used this only once a week, at night. And avoided this on peak hot days. Propolis toner on the other hand was a tad heavy for my combi- leaning-towards-oily skin in the monsoons. But I am so looking forward to using this in Fall.

Used correctly, they balance hydration and exfoliation — two essentials for healthy, glowing skin.

• Choose the Propolis Toner for glow, hydration, and calming benefits.

• Use the BHA Power Liquid for deep pore-cleansing, blackhead reduction, and smoother texture.

Are these going to be a repurchase? I don't think so; not because they are not good, but because there are so many better products in the market.
