I switched to Drunk Elephant day and night serums some time ago and while they are quite expensive, they’re amazing.
The C-Firma day serum is like magic, I see an immediate glow on my skin. It firms the skin, improves elasticity and fixes uneven skin tone. It has 15% vitamin C (which boosts the skin collagen production).
The Framboos Glycolic night serum is AHA/BHA blend which includes glycolic, lactic, tartaric, citric, and salicylic acids which will exfoliate the skin for a clear complexion. A good way to maintain oily t-zone.
