Signal Firming Ampoule 30ml

I've been using the Signal ampoule for about ten or eleven months now. I scraped every last drop out of this one too. I wish they'd make a bigger size. (Reviewed in South Korea)

I use it after my toner. It's gentle on my skin, which I like. (Reviewed in South Korea)

A friend asked me whether my skin had got better, so now I'm using it even more diligently. (Reviewed in South Korea)

I've finally settled my base routine. No more wandering from ampoule to ampoule. (Reviewed in South Korea)

A month of using it and my skin's firmness is definitely changing. (Reviewed in South Korea)

I was given one as a gift, loved it and bought my own. It's a pore ampoule, and my pores do look more orderly. (Reviewed in South Korea)

Not one bit of dryness, and using it consistently I can feel my skin getting bouncier. (Reviewed in South Korea)

It packs firmness in right from under the skin! (Reviewed in South Korea)

A low-irritation formula that's comfortable even on sensitive skin, and a deeply hydrating ampoule that really handles dryness underneath. (Reviewed in South Korea)

No explanation needed. Toner, ampoule and cream — with those three my makeup goes on beautifully. (Reviewed in South Korea)

My mum and I both have this as our favourite brand. Applying plenty before bed, my skin has a glow the next day. (Reviewed in South Korea)

Deeply hydrating without feeling heavy or suffocating, so I'm using it morning and night. (Reviewed in South Korea)

I thought it might feel heavy given how nourishing it is, but it melted right into my skin. It isn't heavy, so it was good to use in summer, and my makeup doesn't pill either. (Reviewed in South Korea)

It's low-irritation so I use it without worry even when my skin isn't behaving, and the texture itself is light, which makes me reach for it more. (Reviewed in South Korea)

Skin type: oily but dehydrated. Use: morning and night. Review: the texture is a tinted ampoule with a slight viscosity. It absorbs lightly and quickly with absolutely zero stickiness. After applying, my skin feels hydrated and matte at the same time. Almost fragrance-free. Strongly recommended for anyone after an ampoule for pores and firmness. The firmness and hydration filling in from underneath is very satisfying. (Reviewed in South Korea)

It isn't heavy, so it's easy to use consistently morning and night. In summer, layering base products usually makes everything lift or pill, and there's none of that here. It's low-irritation, so I use it without worry even when my skin isn't in great shape. (Reviewed in South Korea)

It's like my pores have been firmly tidied up. I'm so happy with it! (Reviewed in South Korea)

Bouncy with no dryness underneath — I love it! I'm already through two bottles and have bought more. (Reviewed in South Korea)

I was given one as a gift and now I keep buying it for other people. I give the three-piece set with one of these ampoules added, so I've ordered again. I love this line — the set together gives such a dramatic result. (Reviewed in South Korea)

I bought another to balance out my set. The serum size is small so you do need to buy extra. This product really is the best. (Reviewed in South Korea)

Honestly amazing. My mum kept saying how bouncy and rich it is, so I told her to use it generously — and she really did, so I've ordered again. I added the Night Ampoule to the order too and honestly, that one is the real deal. She loves it so much she photographs the change every day and keeps recommending it to everyone she knows. She ordered six more of the Night Ampoule this time just to give to friends. This isn't an ad — I paid for it myself. Do try it. (Reviewed in South Korea)

I bought it with the essence and tried it for the first time — so incredibly hydrating. This is exactly the product I'd been looking for. I'll be using it from now on. (Reviewed in South Korea)

So good. The hydration is the best part, and it's given me a confidence boost too. Hope you sell loads. (Reviewed in South Korea)
