Celimax Double Retinal Shot Tightening Booster

Celimax Double Retinal Shot Tightening Booster is the stronger version of the brand's retinal booster — double the retinal, for skin that has already built tolerance and stopped seeing change at the lower strength.

Retinal (retinaldehyde) converts to the skin's active form in one step rather than two, which is why it acts faster than retinol. At double concentration it targets fine lines, loss of firmness and enlarged-looking pores more aggressively.

This is not a beginner product. If you have never used a retinoid, start with the standard retinol or retinal version first.

How to use: evening only, on dry skin after toner. Follow with moisturizer. Start twice a week at most. Sunscreen every morning is mandatory.

Frequently asked questions

How do I know if I am ready for the double strength?
If you have used a retinoid consistently for several months with no irritation and progress has plateaued, this is the next step.

What if my skin reacts?
Stop for a few days, repair with a simple moisturizer, then restart once a week and buffer it under cream.

Can I use it around the eyes?
Not at this strength. Use a dedicated eye product instead.
