Description
Subderma Post-BTX Booster Serum is a concentrated, antioxidant-rich serum from Subderma's Post-BTX Series — a dermo-aesthetic range designed for skin following botulinum toxin (anti-wrinkle) treatments. It deeply hydrates, supports the appearance of smooth-looking skin, and helps protect against environmental stressors and signs of premature ageing.
Formulated with the patented Subderma-Complex (a balance of arginine and niacinamide developed to enhance the delivery of selected actives) and biomimetic peptides, with Ginkgo Biloba Extract and Vitamin C.
Who it's for: anyone who has anti-wrinkle injections and wants a home-care routine designed to support the look of their results between sessions.

Questions before you buy?
Buying with confidence
The things customers most want to know before ordering medical-grade skincare online.
Are your products genuine?
Yes — without exception. Celsia Skin sources every product directly through brand-approved channels, so what you receive is the authentic, sealed item — never grey-market, decanted or counterfeit. We stand behind this with a full-refund genuineness guarantee.
Are you an authorised stockist of Subderma?
We are an authorised UK stockist of ZO Skin Health and other professional, medical-grade brands. It's precisely because these are clinical-strength ranges that some products are consultation-only — authorised stockists are expected to provide suitable guidance, not just sell.
Why are some products consultation-only?
Medical-grade actives can be unsuitable for some skin types or conditions. Gating them behind a free, expert-reviewed assessment keeps you safe and helps you get results rather than irritation.
How will my order arrive?
Orders are dispatched in discreet, unbranded packaging via tracked UK delivery, with FREE next-working-day delivery on all orders. You'll receive tracking by email so you can follow it to your door.
Can I return it if it isn't right for me?
Unopened items can be returned within 14 days of delivery for a refund. For hygiene reasons, opened skincare can't always be resold — do reach out and we'll help find the right alternative.
Can I get advice before I commit?
Absolutely. Our free online consultation pairs you with a qualified professional who'll confirm whether this product suits your skin and goals before you spend a penny. You can also message our team directly with any question.
Still unsure? Message our team before you order.
