Maya's read

The Ordinary Caffeine Solution 5% + EGCG Eye Serum is a serum built around Glycerin, Hyaluronic acid and Lactic acid. It leans strongest on hydration, barrier repair. Best suited to dry, dehydrated and normal skin. Go slow — the active is potent enough to irritate if overused.

Skip it if your barrier is already sensitised or compromised: the acids can sting broken or over-exfoliated skin.

What's in it that matters

The molecule doing the workGlycerinHumectant · strong evidence

Classic humectant with strong evidence for improving skin hydration and supporting barrier when combined with emollients.

  • Hyaluronic acidHumectantstrong evidence

    Water-binding molecule that increases hydration; works best under occlusive/emollient layers to reduce evaporation.

  • Lactic acidSupporting Activemoderate evidence

    AHA that provides gentle exfoliation and some humectant effect; generally milder than glycolic but still pH-dependent and potentially irritating.

  • CaffeineSupporting Activemoderate evidence

    Stimulant molecule that can mildly reduce puffiness and vascular dark circles by improving microcirculation and exerting antioxidant effects around the eye area.

  • EGCG glucosideSupporting Activelimited evidence

    A water-soluble, sugar-stabilised form of EGCG, the main green tea polyphenol. It is in a formula as antioxidant support, not as the ingredient doing the heavy lifting.

  • Pentylene GlycolHumectantmoderate evidence

    Short chain diol that works as a light humectant, co solvent and preservative booster. It keeps a formula less sticky and microbially stable while hydrating the outer layers.

Worth knowing: Lactic acid sits below that line. It is in there, and the label does not tell you how much. That is not the same as saying it is too little to matter.
