Walk down any skincare aisle and you'll find dozens of "actives" competing for your attention. Some have decades of research behind them. Others are mostly marketing.
This guide sorts them out: what each one does, how strong the evidence is and how to build a routine that doesn't overwhelm your skin.
First, what counts as an "active"?
An active is an ingredient that does a specific job beyond basic cleansing and moisturizing, like protecting against sun damage, smoothing the look of fine lines or evening out tone. The rest of the formula (oils, water, emulsifiers) helps deliver it and keeps skin comfortable.
The foundation: sunscreen and moisturizer
Before any exotic ingredient, start here. According to the American Academy of Dermatology, sunscreen and moisturizer are the most effective anti-aging products you can use.
- Sunscreen: broad-spectrum, SPF 30 or higher, every day.
- Moisturizer: traps water in the skin, which helps fine lines look softer.
Everything else on this list works better on top of these two habits.
The anti-aging actives, compared
| Active | Best for | Good to know |
|---|---|---|
| Retinoids | Fine lines, uneven tone, texture | Can irritate; use at night; avoid in pregnancy |
| Peptides | The look of firmness and fine lines | Gentle; studies are promising but small |
| Growth factors & conditioned media | Overall skin quality and radiance | Newer category; research still early |
| Hyaluronic acid | Hydration, plumper-looking skin | Works best on damp skin |
| Antioxidants | Everyday environmental stress, dullness | Pairs well with morning sunscreen |
| Exosomes & PDRN | Trending "regenerative" ingredients | Lots of hype; check the source and data |
Retinoids: the most studied option
Retinoids are vitamin A derivatives. The American Academy of Dermatology notes that retinol is routinely used to improve uneven tone, pigmentation and texture, and prescription tretinoin helps reduce the look of fine lines.
The trade-off is irritation. Dermatologists recommend starting with the lowest strength every other night, using them only at night and wearing sunscreen during the day. If your skin doesn't tolerate them, there are good retinol alternatives, like bakuchiol.
Peptides: gentle messengers
Peptides are short chains of amino acids that send signals to the skin or carry minerals to it. Signal peptides like Matrixyl and carrier peptides like copper peptides (GHK-Cu) have the most research. Read our full guide to peptides in skincare.
Growth factors, conditioned media and exosomes
These come from the world of stem cell skincare. Growth factors are signaling proteins; exosomes are tiny vesicles cells use to communicate; stem cell conditioned media contains both, plus peptides and antioxidants. A 2025 systematic review found these ingredients "appear to be safe and potentially effective" for the look of skin, while calling for more high-quality studies.

Several actives, one jar
This is the category our own formula comes from. Dr. Joy Kong built CharaOmni around stem cell conditioned media, then added peptides, hyaluronic acid and antioxidants, so four rows of the table above go on in a single step. If you'd like to see how your skin gets along with it before committing to a full jar, the 15 ml size is a good place to start.
The best active is the one your skin tolerates and you'll actually use every day.
Hydrators and antioxidants
Hyaluronic acid holds water in the skin, so it looks plumper and smoother right away. Antioxidants like vitamin C help defend against everyday environmental stress. Just note that some pairs need care, like copper peptides and vitamin C.
The newer names: PDRN, NAD+ and botanicals
PDRN, NAD skincare and botanical skincare are getting a lot of attention. Some have interesting early research; most need more. And if you're wondering what "clean" really means on a label, read our guide to clean skincare.
How to choose without overloading your skin
- Pick your main concern. The American Academy of Dermatology recommends targeting your number-one concern rather than everything at once. If yours is uneven tone or dark spots rather than lines, look for a formula built around that; it's why we make a separate Anti-Pigmentation version of our cream.
- Add one product at a time. Using several anti-aging products together can irritate skin, and irritation makes aging signs more visible.
- Give it time. Most products take at least six weeks to show results, and some up to three months.
- Don't judge by price. Effective products come in every price range.
For how all of this fits into the bigger picture, see our guide to aging skin.
The bottom line
Start with sunscreen and moisturizer. Then add one well-chosen active for your main concern and give it at least six weeks. Fewer, better products almost always beat a crowded shelf.
