o'earth Triple Layer HyaluronCica 7sec Serum in Ampoule: What It Is, What's Inside, and Who It's For
A fast-absorbing, fragrance-free ampoule-serum that layers hyaluronic acid and Cica actives for quick, deep hydration on any skin type.
The o'earth Triple Layer HyaluronCica 7sec Serum in Ampoule is a low-pH hydrating serum that combines an 11-type hyaluronic acid complex with six Cica actives to deliver rapid moisture and calm reactive skin. It is fragrance-free, the brand describes it as vegan, and it can be used morning and night as the serum step.
Who This Is For
If your skin tends to feel tight, reactive, or perpetually thirsty — regardless of whether it runs dry, oily, or somewhere in between — the o'earth Triple Layer HyaluronCica 7sec Serum in Ampoule was built with you in mind. The formulation is designed to address dehydration and sensitivity at the same time, so it works across a wider range of skin types than most single-focus serums do.
Sensitive skin types may find it relevant: it is fragrance-free, and the brand describes it as vegan. If you are pregnant, breastfeeding, recovering from a procedure or using prescription skincare, check the brand's current guidance and ask your doctor.
Those with compromised or reactive skin barriers should still perform a patch test before applying it all over the face — that guidance comes directly from the brand, and it is worth taking seriously if your skin is going through an especially sensitive phase.
What It Is and How It Feels
This is an ampoule-serum, which sits between a lightweight essence and a concentrated serum in terms of delivery. The texture is a thin, serum-style liquid that the brand says absorbs within seven seconds — hence the name. In practice, that means it does not sit on top of the skin or leave a film; it disappears quickly and leaves the skin feeling plumped rather than coated.
The formulation is built on a low pH base, which helps active ingredients absorb efficiently and keeps the skin's acid mantle intact. For most people, it will feel like a cooling, slightly silky step that settles immediately and layers easily under moisturizer or SPF.
The Ingredients That Matter
The headline complex is an 11-type hyaluronic acid multi-layering system, combined with six Cica actives. Hyaluronic acid in its various molecular weights can draw moisture to different depths of the skin, and pairing multiple forms is a common approach in Korean hydration serums to address surface and deeper dehydration at once. The Cica component is there to soothe.
