Why Serum Pills Under Sunscreen and Makeup: Best Swaps

SKIN1004's Madagascar Centella Ampoule (100ml, checked 2026-10-06) is a serum built from seven ingredients, and not one of them is a film-forming polymer, which is the detail that decides whether a serum pills and rolls off once sunscreen and makeup go on top of it. Pilling, and the rolling off that often comes with it, is not random: across the ingredient lists and retailer reviews gathered for this comparison, it turns up most often where a water-based serum lists Carbomer, Ammonium Acryloyldimethyltaurate/VP Copolymer, or a silicone such as Dimethicone, sitting under a sunscreen film before the serum has fully absorbed. Check what is actually in the layer under your sunscreen before judging it by how heavy or light it feels on skin, because a thin-feeling serum can still list a gelling agent that balls up once foundation presses down on it, and that is the axis that decides which lightweight serum is a safe switch and which is not.

SKIN1004 Madagascar Centella Ampoule 100ml

SKIN1004 Madagascar Centella Ampoule 100ml is priced at USD 17.60 (checked 2026-10-06) on the brand's official product page, with 55ml and 30ml sizes sold alongside it. The formula runs to seven ingredients in total, led by Centella Asiatica Extract for soothing and Glycerin and Butylene Glycol for the humectant work, with no acrylate gel, no Carbomer, and no silicone anywhere on the list. The texture is thin and spreads like water, and the brand's own instruction is to pat a small amount onto skin until it absorbs instead of rubbing it in. Its pH sits at 5.5-7.5, close to skin's own surface pH, which keeps it positioned for daily use instead of an occasional treatment.

• Pats in without leaving a sticky film, which matters directly for the layer that sits right under sunscreen and makeup.
• Seven-ingredient formula has no Carbomer, no acrylate copolymer, and no silicone to build up under a later SPF film.
• An Epsilon E100 hydration reading on a 22-woman panel (ages 35-65) recorded a 142.28% improvement in immediate skin hydration after one use.
• A Sebumeter reading on a separate 22-woman panel (ages 30-67) recorded sebum falling from 131.82 to 71.55 µg/cm² after one use.
• Sold in 30ml, 55ml, and 100ml sizes, so a daily user and an occasional user can match the size to how often they reapply.

For readers whose serum layer balls up once sunscreen and makeup go on top, the Madagascar Centella Ampoule is the option here: its seven-ingredient formula skips Carbomer, acrylate copolymers, and silicones; it is used by patting a small amount onto skin until it absorbs, before the sunscreen and makeup steps follow.

SKIN1004 Hyalu-Cica Water-Fit Sun Serum UV 50ml

At USD 17.10 (checked 2026-10-06), SKIN1004 Hyalu-Cica Water-Fit Sun Serum UV 50ml sits in the same line as the Centella Ampoule but does a different job: it is the sunscreen step itself, applied between a hydrating serum and makeup. Its formula opens with four chemical filters, led by Avobenzone, calibrated for SPF50+ PA++++ coverage, and adds Centella Asiatica Extract alongside Hyaluronic Acid for the hydration side of the formula. The brand's own product page describes the texture as an ultra lightweight, non-sticky, serum-like formula that leaves a dewy finish with no white cast, and the brand's guide on switching serums under sunscreen and makeup walks through the same layering question this product is built to answer.

• SPF50+ PA++++ broad-spectrum chemical-filter coverage in a single step.
• Non-sticky, serum-like texture, per the brand's own product copy, with a dewy finish and no white cast.
• Combines Centella Asiatica Extract with Hyaluronic Acid and two additional hyaluronate forms for hydration alongside sun protection.
• Sold as a single 50ml bottle or as a twin pack of two 50ml bottles for anyone reapplying through the day.

The Hyalu-Cica Water-Fit Sun Serum UV removes one layer from a serum-sunscreen-foundation stack for anyone currently applying all three separately, since its SPF filters and hydrating actives sit in one watery film instead of two products competing for space under makeup.
