All Skin Types

It’s imperative to wear a high-SPF broad-spectrum sunscreen daily, as retinol can make the skin sensitive to the sun’s rays.


EPION Skin's 4.1 FORTIFY helps to speed up cell turnover and encourage collagen production, which makes it a go-to for those who want to get rid of acnehyperpigmentation, fine lines and wrinkles.

Usage Tips

Start using a pea-sized amount once weekly, slowly building up to every other night. After which, use the retinol serum for two nights on, one night off, alternating with an AHA like EPION Skin's 3.1 RENEW and nourishing serum.


Avoid direct contact with eyes. If eye contact occurs, flush thoroughly with water. Consult a physician if irritation persists. Keep out of children’s reach. For external use only.

Client Reviews

My favourite product till date

Started on the EPION Skin 𝟒.𝟏 𝐅𝐎𝐑𝐓𝐈𝐅𝐘 back in early 2020, and I haven't looked back since.

Staple Skincare Product

Part of my work requires me to try a lot of skincare products, but this serum has become a staple on my dresser — I'm already finishing up my third bottle!
Jilian Quek

My must-have night product

I use it every night and my skin has been reaping its benefits. It not only helps keep my acne at bay, but also makes my skin clearer, and keeps me looking a little younger too.

Great for reducing Acne

In fact, I notice that whenever I start to get tiny acne spots, using my Fortify serum at night gets rid of them the next morning.
