Aeon's C-Bomb Brightening Serum Is Back in Stock: What the Ingredient List Shows

Australian skincare brand Aeon has restocked C-Bomb, a brightening serum that, according to the brand, sold out within 24 hours of its first release. 7NEWS reported the restock on 16 October 2026, and the brand's own store lists it as a 60 ml bottle at 129 Australian dollars. At the time we checked, that page showed a 5.0 average from just nine reviews, which is far too few to say much about how people get on with it.

The more interesting part is the ingredient list. The vitamin C in C-Bomb is not L-ascorbic acid, the pure form used in many acidic water-based serums. It is ascorbyl tetraisopalmitate, a vitamin C molecule with four fatty-acid chains attached. That makes it oil-soluble and much more resistant to oxidation, so it is less likely to turn the bottle orange. The trade-off is that the skin has to convert it back to active vitamin C, and there is far less clinical research on this ester than on L-ascorbic acid. Aeon says the form gives its benefits with less irritation and that the serum was tested on people who struggled with traditional vitamin C, but the page does not publish that testing.

Vitamin C is one of four brightening ingredients named on the label. The others are alpha-arbutin and kojic acid, both of which slow down tyrosinase, the enzyme skin uses to make pigment, and bilberry fruit extract. No percentages are given for any of them. The base is a light emulsion that the brand describes as a cream that disappears into skin, and the directions are two to three pumps morning and night, followed by moisturiser and sunscreen in the day.

Two practical notes from the full ingredient list. It contains clove bud oil, a fragrant essential oil, so people who react to fragrance or essential oils may want to patch test first. And as the 7NEWS piece itself points out, a fast sell-out says nothing about how well a product works or whether it suits sensitive skin.

C-Bomb is sold on the brand's Australian store and is not listed by an official Indian retailer, so it does not appear in our India price comparison.
