A total metamorphosis of the skin. This gentle exfoliating and hydrating face serum takes lusterless skin and transforms it into a bright and glowing complexion. Lightweight and fast-absorbing, look of congestion quickly clears away as fresh, even and dewy skin emerges.


Dry-Normal-Oily Skin | Visible Pores | Dull Skin | Aging Skin

Suitable for all skin types.


Olga’s transformative acid blend helps decongest pores while smoothing away the appearance of fine lines and discoloration.

LACTIC ACID: Gently exfoliating to help lift away dead skin cells while boosting moisture and ceramides, Lactic Acid works to uncover brighter, clearer, fresh-looking skin.

 ALPHA-HYDROXY ACIDS: A synergistic combination of Purified Lactic Acid, Mandelic and Phytic together helps smooth out the appearance of fine lines, soften skin feel & texture, help protect from free radical damage and improve the appearance of hyperpigmentation.

SUPER HYDRATORS: Encapsulated Hyaluronic Acid and Tremella Mushroom delivered into the skin to help draw in moisture while fighting free radicals and improving skin elasticity, leaving skin feeling hydrated and plump.

SKIN SOOTHERS: Palmitoyl Tripeptide-8 soothes skin and reduces the appearance of redness.


After cleansing, smooth 2-3 pumps onto damp face and neck, avoiding the eye and lip area. 

Gentle enough for daily use, stop using if any irritation occurs.

Oily Skin: Wear alone for light hydration. 

Normal-Dry Skin: Follow with a layer of your favorite moisturizer.

Pairs perfectly with the use of retinol & Vitamin C. 

When pairing with retinol: Night time use is recommended, 5 minutes after applying your retinol follow up with Lactic Acid. For a plumper, dewier complexion, continue using Lactic Acid Hydrating Serum after retinol every other night. 

When pairing with Vitamin C: Morning use is recommended, 5 min after applying Vitamin C follow up with Lactic Acid. After products have been absorbed into the skin, follow with SPF. 

We only recommend using multiple active serums to those who have experience using multiple acids at a time. If this is your first time using an acid-based serum, we recommend sticking to just one for 6 months before adding a new one to your regimen.

Olga’s Cocktail: 

For dry skin, or combination skin that can’t make up its mind, mix Lactic Acid with Heal the Need.

For plumper skin faster, follow with the Red Carpet Facial Polishing Mask.

Best treatment for hyperpigmentation

I am in love with this serum. I like that it’s not dry at all and gives me instant glow. It’s has amazing texture that help skin to stay hydrated overnight that repairs the skin even while sleeping.

Transformative even for Sensitive Skin!

Had been introduced to Olga’s Replenishing Toner and moisturizers and was intrigued to try the Lactic Acid Serum but concerned it would be too aggressive for my sensitive skin. Purchased the previous version a few years ago but used sparingly just a few times. After many months of inexplicable breakouts on my T-Zone area - in my late 50’s - reached for the bottle and so pleased it was virtually an overnight remedy!! Have been hooked ever since. Glad the formula changed as the previous one was not compatible with makeup if want to use during the day. The new formula remove glycolic acid - which could be too aggressive but also the gentle aloe vera - which may have caused “pilling”. Already on my second bottle and use once or twice per day. Not only did my breakouts minimize - much more rate - but my skin glows! If my rosacea probed skin can handle should work for most skin types. My only regret is not using religiously sooner. Thank you, Olga!!!!
