SkinCeuticals Phloretin CF Gel Review
The Verdict
Phloretin CF Gel is a well-formulated antioxidant serum for normal, combination and oily skin that wants the same 10% vitamin C, phloretin and ferulic acid combination as the fluid Phloretin CF, in a lighter, residue-free texture. It isn't a stronger or weaker option than the fluid version, just a different base for the same broad skin type — and if active breakouts are more of a concern than tone or texture preference, Silymarin CF is the closer fit.
SkinCeuticals Phloretin CF Gel | Vitamin C Antioxidant | 30ml
£169.00
SkinCeuticals Phloretin CF Gel is a gel-texture antioxidant serum built on the same 10% L-Ascorbic Acid, 2% phloretin and 0.5% ferulic acid formula as the original Phloretin CF, reworked into a lightweight gel base for normal, combination and oily skin. It's formulated to help improve the appearance of uneven tone and environmental damage, worn once daily under SPF.
What is SkinCeuticals Phloretin CF Gel?
Phloretin CF Gel is a 30ml morning antioxidant serum from SkinCeuticals, formulated under the brand's Duke Antioxidant Patent with the same three headline actives as the fluid Phloretin CF: 10% L-Ascorbic Acid (pure vitamin C), 2% phloretin and 0.5% ferulic acid. What sets it apart is the base it's formulated in — a lightweight gel rather than a fluid — designed to absorb without residue and suit normal, combination and oily skin that prefers a fresher, less rich finish. Once absorbed, SkinCeuticals states the serum remains active in skin for a minimum of 72 hours (three days), the same protection window given for the fluid Phloretin CF, which is why it's a once-daily rather than a reapply-through-the-day product.
It sits in SkinCeuticals' antioxidant serum range next to the fluid Phloretin CF, the blemish-focused Silymarin CF and the drier-skin-focused C E Ferulic.
Key ingredients & concentrations
| Ingredient | Concentration | Role |
|---|---|---|
| L-Ascorbic Acid (Vitamin C) | 10% | Primary antioxidant; helps improve the appearance of uneven tone and environmental damage |
| Phloretin | 2% | Plant-derived antioxidant carried over from the fluid Phloretin CF formula |
| Ferulic Acid | 0.5% | Supports the stability and antioxidant activity of the formula |
| Base | Gel | Lightweight, residue-free texture aimed at normal, combination and oily skin |
DATA GAP: the product's Shopify listing also describes general "clinical studies" showing progressive improvement in discolouration and tone, without attached percentages, sample sizes or study references. In line with the no-invented-clinical-claims rule, that language hasn't been repeated here — only the sourced concentrations, base and 72-hour efficacy claim above are used.
Gel vs fluid: Phloretin CF Gel vs Phloretin CF
Phloretin CF Gel shares its three headline actives and concentrations with the fluid Phloretin CF — the difference is texture, not strength. The fluid version suits normal-to-oily and combination skin that's comfortable with a traditional serum feel. The gel is formulated for the same broad skin type but with combination and oily skin specifically in mind, using a base designed to absorb quickly without leaving residue or tackiness behind, which is why SkinCeuticals frames it as the option for anyone who finds a standard vitamin C serum too rich or heavy. Neither formula is "stronger" than the other; picking between them comes down to which texture your skin, and your routine, gets on with better.
Who it's for
- Normal, combination or oily skin wanting a daily antioxidant serum with a light, residue-free finish
- Discolouration, hyperpigmentation, sun damage or uneven tone linked to environmental exposure
- Anyone who's found the fluid Phloretin CF, or other vitamin C serums, too rich for their skin
- People layering an antioxidant step under SPF as part of a daily morning routine
DATA GAP: the page brief for this product also flagged mature and acne-prone skin as suitability points. SkinCeuticals' own product description for this item names normal, combination and oily skin types and discolouration, sun damage and environmental-ageing concerns specifically — it doesn't separately call out mature or acne-prone skin, so those claims haven't been asserted as fact here. If active breakouts are the main concern, Silymarin CF is SkinCeuticals' own blemish-focused vitamin C serum and is worth asking our team about instead.
How to use it
Phloretin CF Gel is a once-daily AM step, applied to cleansed, dry skin before moisturiser and SPF — it's designed to sit alongside sunscreen, not replace it. The gel absorbs quickly and is built to layer cleanly under the rest of a morning routine without pilling. As with the fluid version, the concentration of L-Ascorbic Acid means some people notice mild tingling on first use; this is a normal response to the formula's acidic pH and typically settles with continued use. Patch test on a small area first if you've reacted to vitamin C or acid-based products before, and if irritation persists, space out applications or ask our team for advice rather than pushing through it.
Phloretin CF Gel vs Silymarin CF and C E Ferulic
Phloretin CF Gel is designed as a standalone AM antioxidant step, not one to layer with SkinCeuticals' other vitamin C serums on the same day. Silymarin CF pairs vitamin C with salicylic acid for oily, blemish-prone skin dealing with congestion as well as tone, while C E Ferulic pairs a higher, 15% vitamin C concentration with vitamin E for normal, dry and sensitive skin focused on visible ageing rather than oil control. Our C E Ferulic vs Phloretin CF comparison covers the fluid formulas' differences in more depth — the same skin-type logic carries across to the gel. If you're not sure which serum fits your skin, our team can help you choose one rather than combining them.
Safety, sensitivity and pregnancy
Mild tingling on first use is a normal response to the formula's acidic pH and usually settles with continued use; stop and seek advice if irritation is significant or doesn't ease off. DATA GAP: fragrance status and full allergen listing weren't pulled from Shopify metafields in this session, so aren't stated as fact here — check the product packaging or ask our team if you're fragrance-sensitive. If you're pregnant or breastfeeding, please contact our team for advice before use.
Phloretin CF Gel: the verdict
Phloretin CF Gel is a well-formulated antioxidant serum for normal, combination and oily skin that wants the same 10% vitamin C, phloretin and ferulic acid combination as the fluid Phloretin CF, in a lighter, residue-free base. It's not a stronger or weaker option than the fluid version — just a different texture for the same broad skin type.
