Clarifying Facial Serum Base

No reviews yet

Clarifying Facial Serum Base is a fluid serum for blemish-prone face fills, with niacinamide and zinc PCA. It is a development reference, not a drug treatment. 50 kg MOQ.

How To Use Bases

These bases are formulated so you can customize them. You may add up to 15% purified water, oils, or other ingredients without disturbing the preservative system.

How to Fill Jars

Work in a clean, sanitary space. Use a manual filling machine, a piping bag, or a large squeeze bottle to fill bottles and jars.

How much Fragrance or Essential Oil to add

Stay within the maximum percentage recommended for that fragrance or essential oil, and do not go over it. Gels often thin out once they are scented. If that happens, a gel thickener can bring the body back.

Freeze–thaw / thermal cyclingConfirm no phase split, precipitation or irreversible darkening after cycling.
Preservation challengeValidate the preservative system against the selected formula and packaging before scale-up.
Light / packaging compatibilityPrefer opaque or UV-protective packs where actives need light protection; check leachables and pump/dropper fit.
pH window controlHold the finished chassis near pH 5.0–6.0 unless the approved brief states otherwise.
Document gateRelease only after TDS/SDS, specification and batch COA identity are approved for the confirmed formula.
