★★★★★

Bought it after reading the ingredient list twice. It is doing exactly what the list suggested it would.

Lightweight, calming and my skin genuinely looks better after two weeks. I stopped reaching for anything else in the morning.

★★★★★

Third bottle. I keep trying other things and I keep coming back to this one.

The first one I have worn every day without resenting it. No cast, no pilling under makeup.

Olha R. · Lviv Verified purchase30 ml

★★★★☆

Lovely on the skin. The pump sticks occasionally, which is a small annoyance at this price.

★★★★☆

Does what it says, though it takes a solid month before you notice. The bottle is smaller than I expected.

My dermatologist suggested something with this exact actives list. Six weeks in and the redness is gone.

Ordered on Tuesday, here on Wednesday, and someone actually answered when I asked what to pair it with.

The texture is the reason I repurchase. It disappears instead of sitting on top of everything else.

My skin was reacting to everything in August. Two weeks on this and it has calmed down completely.

Does the job quietly. I noticed it most when I ran out and went two weeks without.

Good texture, absorbs fast. I would prefer it without any scent at all, but it is very mild.

Honestly expected marketing. Got a product my skin has not reacted badly to once in three months.

Good formula, slow results. If you want something in a fortnight this is not the one.

Packed carefully, batch code matched, and the texture is identical to the one I bought abroad.

Diana F. · Kyiv Verified purchase30 ml

★★★★☆

Really pleasant to use morning and evening. Wish the bottle were bigger for the money.

Halyna O. · Poltava Verified purchase30 ml

★★★★★

The one product I have not swapped out all year. It behaves the same in June as it did in January.

Vita S. · Cherkasy Verified purchase30 ml

★★★★☆

Sensible formula, no fragrance, no drama. Exactly what I was looking for.
